Product Information

Schools, universities and offices often are hotbeds for COVID-19 spread. This is no surprise since there are many people in closed environments like classrooms, so it can be a nightmare to ensure all safety precautions are met. The Centers for Disease Control and Prevention, WHO, NIAC and the HSE have warned that COVID-19 can spread via aerosols. These are small droplet particles containing the SARS-CoV-2 virus – a serious risk factor that has to be considered indoors. The best way to combat it is to ensure proper air exchange. How can you know if the air quality is good? This is where Aranet comes in!

The Aranet4 PRO sensor is an innovative battery-powered wireless plug-and-play device with on screen display showing the monitoring of CO2, temperature, relative humidity and atmospheric pressure at home, school, office or other indoor environments. The sensor is portable, simple to install, easy to operate and lets you know when CO2 levels have become unhealthy and a sound will alert the occupants to take action to increase the airflow. 

Furthermore Google play and Apple Store Apps allow the user to setup and use the product within minutes. Settings can be altered to suit your needs.

To stop thieves the Aranet4 has a anti-theft wall mount (sold separately). The wall mount uses a Security screw that needs a screwdriver with a Torx T15 insert bit to remove it.

The Aranet4 PRO sensor is compatible with Aranet Cloud. This service is an industrial grade solution for IoT ecosystems’ remote management. Personalise your data with custom dashboards, graphs and user management. It can be sold with or without a Aranet Base Station for centralised monitoring with models for 12 units, 50 units and 100 units
