SPECIFICATIONS

product description:

        the product adopts industrial chip, imported with high precision SHT20 the temperature and humidity sensor ensures the excellent reliability, high precision and interchangeability of the product. Using RS485 the hardware interface (with lightning protection design ), the protocol layer is compatible with the standard industry Modbus-Rtu protocol. The present set of products MODBUS the protocol is integrated with the common protocol. Users can choose the communication protocol by themselves. The common protocol has the automatic upload function ( connection RS485 the temperature and humidity will be automatically output through the serial port adjustment tool).
