LoRaWAN Temperature and humidity sensor

Made by
Dingtek is a certified partner.

Description

The DT300 is integrated air temperature & humidity sensor. The sensor use sensorion® SHT31 temperature/humidity ic. It is compact design with small dimension and easy for installation. It is applicable for home, industrial room, greenhouse, cabinet and other cases..

Wth LoRaWAN wireless module, the sensor data is sent to the network server via gateway. Finally user can monitor the status remotely. It is optional for frequency 470Mhz(CN), 868Mhz (Europe), 915Mhz(USA), 923Mhz(Australia).

As it is with algorithm of low power consumption, the internal battery work for more than 1 year.

Humidity sensor are generally hygroscopic substance impregnated in the insulating material, or by evaporation of the coating layer made of metal and other technology, a semiconductor, a polymer film, and the production of the powdery particles, the moisture in the moisture sensitive element and desorption process, the water molecules into H + ions out of the conducting state is changed, so that the resistance value of the element with the humidity.
