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.
Description Aranet Sensor Aranet4 HOME CO2
The Aranet4 sensor is a battery powered CO2 meter with additional measurements of temperature, relative humidity and atmospheric pressure.* The device is suitable for monitoring the CO2 level in indoor environments such as at home, in office or at school.

* 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!
Measurement data are displayed on power-efficient e-ink screen allowing for long battery life. Additionally the device can provide a visual and sound notifications in case the CO2 level surpasses the high concentration level of 1400 ppm (parts per million) – level typically associated with complaints of drowsiness and poor air quality. Aranet4 uses the most precise Nondispersive infrared (NDIR) sensor technology for accurate CO₂ measurements. It has a super-efficient e-ink display that extends it’s battery life up to 2 years (2xAA).
