With the enforcement of Article 560 of the Rules on Occupational Safety and Health Standards from 2025, the importance of managing perceived temperature in the workplace has greatly increased. Accordingly, the need for smart thermometers that can measure and manage perceived temperature in real time, rather than devices that simply display temperature, is increasing.
Ace Development Co., Ltd. is registered as a meteorological company and directly develops and manufactures the Senso T series smart sensory thermometer that meets the standards of the Korea Occupational Safety and Health Agency.
Today, we will take a closer look at the differences between T1 and T5 through comparison of the smart sensory thermometer T series.
What is the smart sensory thermometer T series?
Senso T Series is a smart sensory thermometer product line that can be selected depending on the size and management purpose of the site.
All models basically measure perceived temperature, and as higher models go up, various functions are added, such as electronic display function, linkage with the Korea Meteorological Administration, weather forecast, and external electronic display output.
In addition, it is designed to allow managers to check the status even outside the field by utilizing LTE wireless communication and web and mobile platforms.
What kind of field is the T1 model suitable for?
Senso T1 is the most basic model.
This product uses a small numeric keypad and provides a basic perceived temperature display function.
The recommended installation location is a break room or small workshop.
Suitable for the following sites.
- small construction site
- temporary workspace
- break room
- Places where basic perceived temperature management is required
It is also possible to link an anemometer with a warning light, so it provides sufficient basic functions.
What are the characteristics of the T2 model?
Senso T2 is a practical model with a single-bulb electronic display board.
In conjunction with the Korea Meteorological Administration data, more accurate perceived temperature is provided and visibility has been greatly improved.
The recommended installation location is a local workshop.
Features are as follows.
- District 1 electronic display board
- Meteorological Administration linkage
- LTE communication
- Web and app platform support
- Anemometer linkage
- Warning light interlocking
It has a good balance between price and performance, making it suitable for use at various construction sites.
What is the difference between the most selected T3 models?
Senso T3 is a model with high cost-effectiveness among the T series.
By applying a two-prong electronic display board, not only the perceived temperature but also on-site guidance information can be displayed.
Recommended installation location is the main workplace.
Main features include:
- 2-district electronic display board
- Display perceived temperature
- Meteorological Administration linkage
- LTE wireless communication
- Web/Mobile Management
- Smart signboard function
- Anemometer linkage
- Warning light interlocking
This model is highly useful when information needs to be conveyed in a field with many workers.
Why is T4 suitable for large sites?
Senso T4 is a model for linking with external electronic signs.
By connecting to an existing large LED signboard, perceived temperature and safety information can be displayed in a wide range.
The recommended installation location is as follows.
- large construction site
- main passage
- Worker movement area
- industrial complex
This is a model that can increase management efficiency in sites using large electronic signs.
What features does the highest specification T5 provide?
Senso T5is a comprehensive guided smart temperature sensor.
It has a wireless electronic signboard function that provides weather forecasts and various guidance information.
The recommended installation location is the entrance to a business or large industrial facility.
Main features include:
- Provide weather forecast
- Comprehensive wireless electronic signboard
- LTE communication
- Meteorological Administration linkage
- Web/App Platform
- Output various information contents
- Anemometer linkage
- Warning light interlocking
This is a model that can also serve as a representative guidance system in the field.
What features are commonly provided in all models?
The T series varies from model to model, but is based on the following core functions.
- Measurement of perceived temperature
- Meteorological Administration data linkage
- LTE wireless communication
- Web/mobile platform
- Anemometer linkage
- Warning light interlocking
The higher the model, the more expanded the electronic display and guidance functions are.
How do I select a recommended model for each site size?
Depending on the scale of the site, recommendation models can be classified as follows.
Small-scale field
- T1
- T2
Medium site
- T3
Large site
- T4
- T5
If you only need to display the perceived temperature, T1 or T2 is suitable. If you need to provide worker guidance and safety information, it is more efficient to select a T3 or higher model.
Comparison of smart thermometer T series, which model is best?
The smart temperature sensor T series is not a device that simply displays numbers, but a system designed to manage perceived temperature and weather information in real time using IoT technology.
Each model from T1 to T5 can be selected according to the site size and management purpose, and supports efficient site safety management based on the Korea Meteorological Administration linkage, LTE communication, and web and mobile platforms.
The biggest feature of the T series is that you can choose products to suit a variety of environments, from small sites to large industrial sites.
