Temperature &humidity sensors

SE72x-LoRaWAN Temperature and humidity sensors 

     The SE72x is a wireless temperature and humidity sensor that measures environmental temperature and humidity using a digital sensor, periodically transmitting the readings to an application platform via LoRa. Users can configure the sampling and reporting intervals using a handheld device or management platform, with a default setting of 0.5 hours. It supports both LoRaWAN and LinkWAN protocols and boasts an IP65 protection rating.
