The configurable NB-IoT/LTE-M/LoRaWAN environmental sensor samples, aggregates, reports temperature, humidity, CO₂ concentration, light intensity, barometric pressure and detects motion. Indication of CO₂ concentration by RGB led in the button, which can also be used to send data instantly.
CHESTER Clime IAQ has three built-in sensors. A thermometer is used to measure internal temperature, an accelerometer is used to measure device orientation, and an ADC is used to measure the battery. It also allows for setting optional temperature, humidity, CO₂ concentration low/high alerting.
The device transfers data over cellular networks (NB-IoT / LTE-M) or public / private LoRaWAN networks.
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).
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.
Use the HARDWARIO Manager iOS/Android app to set the device and integrate its data from HARDWARIO Cloud.
