Wireless CO2 and Air Quality Data Logger


Our wireless CO2 and Air Quality data logger is the perfect device for monitoring and recording air quality and carbon dioxide levels at home, at work, in schools and in a whole range of other applications including horticulture.

Measuring carbon dioxide, temperature and humidity, the EL-IOT-CO2 continuously records these parameters, providing you with current, minimum and maximum readings in the bright and clear display for at a glance indication of the air quality.

Set your own high and low alarms for each parameter, when your limits are reached, instant notification of critical changes can be sent to you via email and/or SMS.

The EL-IOT-CO2 is powered via USB power supply and can also use AA batteries for short-term backup if the power supply is interrupted.
