4-20mA RS485 Modbus wall-mounted temperature and humidity transmitter Sensor with display track installation

Basic parameters 



Size

Mounting method: Wall mounting or DIN

Open encloser to Wire

RS485 communication Default parameters: 9600,n,8,1
Default device address is 1
Modbus RTU protocol


E.g. master read temperature humidity:

Sensor responds:

Temperature calculates:
00F8 (HEX)= 248 (DEC)
Output value 0~1650 corresponds to -40~125℃
Temperature=125-(-40)*248/1650-40=-15.2℃

Humidity calculates:
00177 (HEX)= 375 (DEC)
Output value 0~1000 corresponds to 0~100%RH
humidity=374*100/1000=37.5%RH
