A CO₂ sensor unit that measures temperature, humidity, and carbon dioxide concentration. It complies with the « Guidelines for the Selection of Carbon Dioxide Concentration Measuring Devices » established by the Ministry of Economy, Trade and Industry.
The main power source is generated and stored by solar cells, and it is equipped with a backup battery. The backup battery can be used for about 10 years without replacement.
*Only when used with a measurement interval of 15 minutes. Varies depending on installation location/usage environment.
The measurement interval can be selected from 1 minute, 5 minutes, 10 minutes, 15 minutes, or variable mode based on CO₂ concentration. In variable mode, the measurement interval is automatically adjusted according to the CO₂ concentration. In environments where there are no people, such as at night, the measurement interval is extended, which is expected to reduce power consumption.
