SECURUS/Hardware/Air quality sensor

CO₂ sensors for air quality and indoor climate

CO₂ sensors show concentrations at the measurement point and support ventilation assessment. Depending on the device, temperature, humidity and further air parameters are available. SECURUS brings histories together by room and site.

Technical data according to the manufacturer's datasheet, battery life under the stated conditions. All devices shown transmit via LoRaWAN. In addition to these examples, we also use LoRaWAN devices from other manufacturers depending on requirements.

Choose CO₂ measurement and additional air parameters

For classrooms and meeting rooms, decide which readings are needed and whether a local display is useful. Avoid placing the sensor directly beside windows or people. Indoor climate monitoring links readings with agreed alert rules.

FAQ

Sensor selection questions

Does CO₂ fully establish air quality?

No. CO₂ is one measurement. Other pollutants require suitable additional methods.
