This combined true CO2, ambient temperature, and humidity device from Lansen is a plug-and-play transmitter. Great care has been taken to design a device with high security, performance, long battery lifetime (10 years), and maximum range in all directions thanks to two internal antennas. The design allows for discrete integration when mounted in home environment. Furthermore, the device has a quick and easy installation using just a magnet.

This device has both visual and acoustic indications to indicate potential harmful indoor air. The device can be pre-configured to use either visual or acoustic indications. Temperature, humidity, and CO2 is sampled and transmitted at regular intervals which makes the device ideal for integration in data collecting systems which can be preconfigured to directly indicate potential harmful indoor air.
