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.
- The sensor is compatible only with Aranet PRO base station
- Measures: CO2 (carbon dioxide), temperature, relative humidity, atmospheric pressure
- Line-of-Sight range: up to 3 km/ 1.9mi
- Operating environment: indoor use
- Transmitter power: 14 dBm
- Data Transmission: 1,2, 5, 10 minutes
- Battery life: Up to 2 years
- Protection class: IP20
- Dimensions: 70x70x24 mm/2.76×2.76×0.94″

* 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!
Do not use the device in high humidity environments (greater than 85%)!
Do not leave the device in direct sunlight!
