The wiring instructions are as follows:   Applications Widely used in building automation, telecommunications room, papermaking, warehousing and logistics, shopping malls, hotels, cinemas, railway stations, museums, theaters, agricultural greenhouses, hospitals, meteorology, clean workshops and other fields that need to measure air temperature and humidity. Data Conversion Method T: Temperature, unit: ℃ H: Humidity, unit: %RH V: Voltage value collected by collector, unit: V A: Current value collected by collector, unit: mA   Output Signal Temperature Conversion  (at -30~70℃) Humidity Conversion 0～2V DC T=50*V-30 H=50*V 0～5V DC T=20*V-30 H=20*V 0～10V DC T=10*V-30 H=10*V 4～20mA T=6.25*A-55 H=6.25*A-25 RS485 signal (default address 01): Standard Modbus RTU Protocol, Baud Rate: 4800; Parity bit: None; Data Bits: 8; Stop Bits: 1 ① Modify Address For example: Change the address of the sensor with address 1 to 2, Host → Slave Original address Function Code Initial Register high   Initial Register low   Initial Address high Initial Address low CRC16 low CRC16 high 0X01 0X06 0X07 0XD0 0X00 0X02 0X08 0X86   If the sensor is received correctly, the data will be returned in the same way. Remarks: If you forget the original address of the sensor, you can use the broadcast address 0XFF instead. When using 0XFF, the host can only connect to one slave, and the return address is still the original address, which can be used as an address query method ② Query data Query the data(temperature, humidity) of sensor (address 1), Host → Slave Address Function Code Initial Register high Initial Register low Register Length high Register Length low CRC16 low CRC16 high 0X01 0X03 0X00 0X00 0X00 0X02 0XC4 0X0B   If the sensor receives correctly, the following data is returned, Slave→Host   Address Function Code Data length Register 0 data high Register 0 data low Register 1 data high Register 1 data low CRC16 low CRC16 high 0X01 0X03 0X04 0XFF 0XDD 0X01 0X64 0X5A 0X66 　 　 　 Temp.:-3.5℃ (Minus is complement representation) Humidity:35.6%RH 　 　   Attentions (1) When you receive the product, please check whether the packaging is in good condition, and check whether the sensor model and specification are consistent with the product you purchased. (2) The installation place should be far away from chemical corrosion environment. (3) Sensors and wires should be kept away from high-voltage electricity, heat sources, etc. (4) The sensor is a precision instrument and should be stored in a dry, ventilated, room temperature indoor environment. (5) The sensor is a precision device, please do not disassemble it by yourself when using it, so as not to cause product damage. Warranty The instruments are guaranteed by the user for one year from the date of delivery, provided that the rules of use and protection are observed. After one year, maintenance will be carried out in our company. The company welcomes letters and calls from users at any time for consultation and suggestions.
