Milesight EM300-TH-868M, IP67 LoRaWAN Temperature and Humidity Sensor

Many businesses lose money because they cannot see temperature or humidity changes in time. In a cold chain, a few degrees above the limit can spoil products, while excess moisture can cause mold in warehouses. The EM300-TH-868M removes that uncertainty. It measures temperature from -30 C to 60 C and humidity from 0 % to 100 % RH with high accuracy, then sends the data over LoRaWAN to your monitoring platform. You get instant alerts and can correct conditions before loss happens.
