Aranet4 HOME CO₂ sensor

Aranet4 HOME CO₂ sensor

SKU: 4752213000037

Aranet4 is an innovative battery-powered stand-alone wireless sensor for monitoring CO2, temperature, relative humidity and atmospheric pressure at home, school, office or another indoor environment. The device is portable, simple to install, easy to operate and lets you know when the monitored levels have become unhealthy.

* For best accuracy, recommended operating range is 10°C to 40°C (50°F to 104°F) and 20% to 60% RH (non-condensing).
Prolonged operation beyond these ranges may result in a shift of sensor reading, with slow recovery time.
** Bluetooth pairing disabled, LoRa radio disabled, data transmission at a 10 minute interval.

Aranet4 is not impact resistant!
