XY-MD02 - SHT20 Sensor based Temperature and Humidity Transmitter Module with RS485 Modbus Interface
XY-MD02 Temperature and Humidity Sensor Module adopts an industrial-grade chip and high-precision Sensiron SHT20  sensor to ensure excellent reliability & high precision.
RS485 hardware interface (with lightning protection design), the protocol layer is compatible with the standard industrial Modbus-RTU protocol.
XY-MD02 Temperature and Humidity sensor integrates MODBUS protocol with a common protocol. Users can choose communication protocol by themselves. The common protocol has an automatic upload function ( connecting RS485 will automatically output temperature and humidity through the serial port adjustment tool ).
 
RS485 supports 1000 meters of communication
Standard DIN35 mounting rails
Support MODBUS RTU protocol
