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.

Connect via Bluetooth to APP on phone or tablet

Connect to base station with up to 100 units

Connect to Cloud via base station

Office Environment : air conditioned spaces need regular reviews to ensure the air conditioning system is working not only effectively but also with a positive health outcome for the users.

Keeping CO2 levels in the 600 to 1000 ppm range ensures a healthy working environment.

Managers need to be proactive and monitor CO2 along with temperature and relative humidity to ensure a safe environment, and where necessary improve fresh air input and cross flows. This could be as simple as opening a back door or repositioning a fan.

The importance of having the data to make the decisions rests with management of the business. The Aranet4 PRO will allow you to monitor any office environment, recording the data on the sensor, or to a base station and /or to the Aranet cloud for review or reporting via email against preset parameters.


Your local gym is an environment where you can expect higher levels of CO2 within the space, is the gym management monitoring IAQ levels to ensure a safe environment?



Is your favourite shopping centre just relying on their contracted Air Conditioning company to monitor the IAQ in the space – maybe once a month? or is Shopping Centre Management taking a proactive roll in reviewing the air quality for the benefit of all customers?


Is the school that your children attend monitoring IAQ? Air conditioned class rooms are now the norm, what fresh air input levels are used? Does your child suffer from tiredness, fatigue after a day at school? Managing the air quality of the class room is an important factor for today’s educators.

* 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!
