CO2 sensor, LoRa communication, no external power required.

CO2 sensor, LoRa communication, no external power required.

World-class ultra-low power consumption! Contributing to a decarbonized society and the SDGs by utilizing solar and lighting energy.

The "CO2 sensor" is a device used to measure the concentration of carbon dioxide (CO2) in the air and various environmental factors. It is important for managing indoor air quality and does not require battery replacement or wiring. It can significantly reduce the effort of data collection, recording, and management. Additionally, it utilizes LoRa (Long Range) technology, which allows for low power consumption and long-distance communication, with measurement data transmitted via LoRa. 【Specifications (partial)】 ■Dimensions/Weight: W74mm×D122mm×H20mm/87g ■Operating Environment: 0–50℃/indoor use only (illuminance below 1500lx) ■Measurement Targets: CO2 concentration/temperature/humidity/illuminance/atmospheric pressure/voltage value of the built-in lithium-ion battery ■Measurement Interval: Default 300 seconds/setting range 10–600 seconds ■Continuous Operation Conditions: Continuous operation for 24 hours is possible by exposing to 300lx of daylight LED light for 8 hours a day (when the measurement interval is 300 seconds) *For more details, please download the PDF or feel free to contact us.

High-precision CO2 sensor "eAir" that visualizes "secrecy"

High-precision CO2 sensor "eAir" that visualizes "secrecy"

Visualizing air quality in various locations. Making density visible to create a safe space. A trending CO2 sensor introduced on NHK and TV Asahi news programs.

● Preventing the "three Cs" (closed spaces, crowded places, close-contact settings) in conference rooms and stores to implement infection prevention measures. By accurately measuring and visualizing the CO2 concentration in the space, efficient ventilation can be achieved. It can also measure room temperature and humidity, providing reliable ventilation guidelines and air conditioning management—benefits unique to "eAir." ● No setup required. Ready to use right out of the box. eAir can be used immediately after being taken out of the box without the need for additional devices or settings. The CO2 concentration is clearly displayed with a dual indication of four-color LEDs and real-time numerical values. ● Even more convenient! Check CO2 concentration from a distance with app integration. By linking the app, you can monitor CO2 concentration on your iPhone or Android smartphone even when you are not on-site. By monitoring air quality from various locations, such as building management centers or while out, you can gain greater peace of mind. High-precision measurement with NDIR technology specialized for CO2 concentration. It allows for more accurate and quicker visualization of the three Cs with the CO2 monitor, enabling immediate actions such as starting ventilation.
