CHESTER
Clime IAQ

CHESTER Clime IAQ is a configurable indoor air quality sensor with wireless connectivity (NB-IoT/LTE-M/LoRaWAN). It measures temperature, humidity, and CO₂ concentration, enabling effective monitoring and control of indoor air quality.

Applications: air quality monitoring in offices, environmental monitoring in schools, air control in hospitals, etc.

Battery-friendly wireless connectivity

The device transfers data over cellular networks (NB-IoT/LTE-M) or public/private LoRaWAN networks.

Buzzer and LED button

The buzzer acts as an acoustic response to the LED button press. It can also serve as an alarm if measured variables exceed set limits (temperature or CO2).

Reliable power supply with backup battery

CHESTER Clime IAQ is powered from external power supply from 6 to 28 VDC and includes backup Li-pol battery with lifespan up to 1 year.

Fast deployment and seamless integration

Use the HARDWARIO Manager iOS/Android app to set the device and integrate its data from HARDWARIO Cloud.
