How it works

The ZED-THI-M is a battery powered device which perform temperature and humidity measurements at the same time and send them at regular intervals to a Gateway of the 4-noks products family. This device may be configured to manage alarm thresholds for exceeding maximum or minimum levels of measures. It is also possible to adjust the sampling and data transmission rate to improve battery life.
