When passing by a construction site or industrial facility, you can easily see electronic signs displaying fine dust and noise levels.
At first, I thought it was a device that simply shows the surrounding air condition and noise level. After looking into the details, I found out that it is an integrated environmental management system that wirelessly transmits data measured by sensors, stores it on a server, and checks it on PC and mobile.
The place we will look at today is , which develops IoT solutions in the fields of construction safety, environment, and weather, and from Ace Development.
Among them, today we will summarize from a third party's perspective what items are measured and how they are used in the field, focusing on the sensor unit of the environmental monitoring system.
What kind of company is Ace Development?
Ace Development is an IoT specialized company in the fields of construction safety, environment, and weather, established in 2016.
We are directly developing sensors, communication modules, electronic signs, and monitoring platforms based on wireless communication and device control technology.
When I looked into it, I found that it was not simply a combination of external equipment and had a consistent technical system from PCB design to communication, server, and platform services.
It has been confirmed that it has accumulated related technologies for more than 10 years and has secured 6 patents, 4 KC certifications, and 1st grade performance certification from the Ministry of Environment.
It was also noticed that the company was expanding its scope to include not only construction site environmental management but also weather monitoring, smart safety, and wireless IoT business.
How is the environmental monitoring system structured?
Ace Development's environmental monitoring system consists of four major steps.
It consists of a sensor unit that measures on-site environmental data, a wireless communication unit that sends the measured data to the server, a display unit that displays the numbers on site, and a monitoring unit that checks on PC and mobile. Data measured by the
sensor is transmitted to the server through a self-developed LTE communication module. The collected information can then be checked on the PC web and Android app SENSO-LINK, and is also displayed in real time on the on-site electronic signboard.
When I looked into it, it was not a simple installation of a single measuring device, but rather an integrated solution that connects everything from measurement to transmission, storage, analysis, and display.
In particular, those in charge of managing multiple sites at the same time will likely find map-based real-time monitoring and data storage in Excel practical useful.
Why is the sensor part important? In the
environmental monitoring system, the sensor unit is located at the very front.
No matter how fast the communication speed is and how good the monitoring screen is, if the initial measurement value is inaccurate, the reliability of the entire system will inevitably be lowered.
Ace Development's sensor unit is configured to measure fine dust, noise, vibration, and nitrogen dioxide. Depending on site conditions, only one type can be installed alone or multiple sensors can be integrated and operated.
At construction sites, it is often necessary to manage flying dust, heavy equipment noise, and blasting vibration together. I found it satisfying to be able to check multiple items in one system.
Since you can select only the sensors you need, it seemed convenient to adjust the configuration to suit the site scale and management purpose. What does the
fine dust sensor measure?
Ace Development's fine dust sensor is a product that has received Ministry of Environment performance certification No. 2025-p-2, grade 1 performance certification.
measurement range is from 0 to 1,000㎍/㎥ and can measure not only PM2.5 and PM10, but also temperature, humidity, carbon dioxide, and VOC.
The measurement method is laser scattering and the warm-up time is less than 8 seconds. Operating conditions are also indicated as -20 degrees Celsius to +60 degrees Celsius, so it appears to be a good configuration for use even in outdoor sites with large seasonal changes.
Measurement values are transmitted every 2 minutes via LTE Cat.1 communication. When I looked into the
, it turned out to be closer to a complex environmental sensor that broadly captures the on-site air environment rather than a single sensor that only checks fine dust.
However, the Ministry of Environment's performance certification items are fine dust and carbon dioxide, and other temperature, humidity, and VOC values are instructed to be used for reference.
The fact that the certification scope and reference items were separated and disclosed also gave a sense of trust when looking at product information. How is the
noise sensor used in the field?
noise sensor is a product that has obtained environmental measurement device type approval NESM-201.
measurement range is 30 to 130 dB, resolution is 0.1 dB, and accuracy is ±1.5 dB. You can measure various types of noise data such as SPL, SEL, Leq, maximum value, minimum value, and peak hold.
Supports both A-weighting and C-weighting and allows selection of Fast, Slow, and Impulse response speeds, enabling detailed measurements depending on field conditions.
At construction sites, both momentary and continuous noise occurs due to the operation of heavy equipment, cutting materials, and demolition work.
This sensor not only shows the current decibel, but also can check the average noise, maximum noise, and instantaneous peak value, so it seems to be very useful for responding to civil complaints or managing the work environment.
The data transmission cycle is also set to 30 seconds, so I was satisfied with being able to check frequently changing field noise relatively quickly.
In what situations is a vibration sensor needed? The
vibration sensor is a device that measures vibrations generated during blasting work or the operation of heavy equipment.
This product has received environmental measurement equipment type approval NEVE-19. The measurement range is 45~120dB[V] and the frequency range is 1~90kHz.
The measurement axis is Z-axis and supports Fast and Slow time characteristics. Measured values are provided in the form of Lmax, which is the maximum vibration value, and L10, which checks the vibration level in a certain range.
As I found out, vibration is difficult to directly check with the naked eye, so if you try to check the cause after a complaint occurs, it is not easy to accurately determine the situation at the time. By continuously recording vibration data through the
sensor, you can compare changes before and after construction or vibration levels during specific work times.
It seemed to be particularly useful in sites where demolition, excavation, driving, and blasting work is taking place, or in construction sites close to residential areas.
Why is a NO₂ sensor needed?
NO₂ sensor is a sensor that measures nitrogen dioxide concentration.
measurement range is 0.05~10ppm, operating voltage is 3.3~5V DC, and current consumption is less than 5mA. It supports analog, I²C, and UART output methods and can use up to 32 I²C addresses.
Nitrogen dioxide is an air pollutant that can be emitted from vehicles, heavy equipment, and combustion facilities.
At sites where a lot of construction equipment moves or in sections with high vehicle traffic, it is necessary to check not only fine dust but also gas concentration. By adding the
NO₂ sensor, you can expand the scope from existing environmental management focused on dust and noise to air pollutant gas management.
has low power consumption and can connect multiple sensors, making it suitable for sites that want to operate various measurement points.
What role does the wireless communication department play? The information measured by the
sensor unit is transmitted to the server through a self-developed gateway board and LTE modem.
communication method is LTE FDD Cat.1 and data is exchanged using TCP/IP method. Interconnection with external devices using UART and TTL methods is also supported.
KC certification number is indicated as R-R-jbq-SENSO-MCH.
After research, I found out that the role of the communication department in stably transmitting measurement data was more important than installing only sensors.
Even if an administrator is not present on site, once the data is sent to the server, the current situation can be checked from the office or outside.Since the
sensor and communication module were developed together, it was felt that there would be advantages in terms of compatibility between devices and response to failures. Where can I check the
measurement data?
Collected environmental data can be viewed on the PC web and mobile app SENSO-LINK.
You can view measurement values for each site in real time on a map-based screen, and receive automatic notifications when the standard value is exceeded.
Recorded data can be saved as an Excel file, making it ideal for daily reports, monthly reports, civil complaint response data, and ordering company submission data.
Additionally, workers and nearby residents can immediately check the current measurement values through the electronic display board installed at the site.
I also felt positive about being able to share numbers with field members rather than a closed system where only managers see the data.
What kind of field should it be applied to?
Ace Development's environmental monitoring system sensor unit can be applied to various places such as construction sites, demolition sites, blasting sites, factories, logistics centers, and road construction sections.
Urban construction sites where fine dust complaints are frequent can be configured with fine dust and noise sensors.
Vibration sensors can be added at sites with a lot of digging or driving work, and NO₂ sensors can be linked to manage exhaust gases from heavy equipment and vehicles together.
Another advantage is that each sensor can be configured individually or integrated, so there is no need to apply the same equipment to all sites.
I thought it was a practical system because you can select the necessary equipment according to the risk factors, budget, and management items of the site.
What are the advantages of the Ace Development sensor unit that we have seen in person?
While looking at the Ace Development sensor department, the most impressive part was that the sensors, communication, and platform were developed directly by one company.
The fact that it has a grade 1 fine dust sensor certified by the Ministry of Environment and a noise and vibration sensor that has received environmental measurement device type approval also increases reliability.
also seemed to have a wide range of use as only the necessary sensors could be selected depending on the field situation and measurement values could be shared through PC, mobile, and electronic signboard.
It seems to be helpful for long-term environmental management as it not only measures numbers but also stores and analyzes data.
The more I looked into it, the more I felt that it was not just a device for managing fine dust and noise complaints at construction sites, but an IoT platform that systematically accumulated field environmental data.
Is Ace Development’s environmental monitoring system satisfactory?
When it comes to environmental monitoring equipment, the accuracy of measurement values and data management method are more important than the installation itself.
In that respect, Ace Development seemed to have a strength in integrated management as it was equipped with certified sensors, its own wireless communication module, and a PC/mobile monitoring platform.
In particular, I was satisfied with the fact that fine dust, noise, vibration, and NO₂ could be combined to suit the site, and that data transmission and electronic display display were all connected at once.
It felt like an environmental monitoring system worth considering at least once for companies that need to prevent environmental complaints at construction sites or systematically manage measurement data.
