The Wireless Temperature and Humidity IoT Sensor are low power comsuption design,it is a wireless Internet of things gateway, designed for converting AM2301 Temperature and Humidity sensor signal to Wireless communcation over SMS/GPRS/3G/4G/NB-IoT Cellular Network, and connect to the IoT Cloud Platform.
The Wireless Temperature and Humidity IoT Sensor is widely used to real time remotely monitoring temperature and humidity of Refrigerator freezer, chicken factory, chemical plant, food production and storage, warehouse, hospital etc.
The wireless temperature IoT Sensor supports Modbus TCP Protocol and MQTT Protocol, compatiable KPIIOT cloud platform and other cloud platform or SCADA or OPC Server.
