Temperature and Humidity Sensor

Made by
AllIoT is a certified partner.

Description

Netvox’s wireless air temperature and humidity sensor collects and transmits readings to give accurate measurements allowing you to monitor any changes in environment. The wireless sensor sends the alert messages to a centralised monitoring system via the LoRaWAN protocol at pre-programmed intervals.
