New BGT-WSD2 Atmospheric Temperature&Humidity Sensor is a professional measurement of ambient temperature and relative humidity. Sensors are built-in the water-proof and anti-UV shelter. 7 plates radiation shield is used to protect weather sensors and provides more accurate measurement results. The shield minimizes radiation reaching the sensor, minimizes radiation absorbed by the shield and max imizes ambient air flow around the sensor. It is widely used in agriculture, forestry, meteorology as well as a climate chamber, warehous ing and other places.
1. If you are using a single sensor connected to the computer to read data directly, it is recommended to use the ASCII private protocol,you can visual display in ASCII (hex send, non-hex receive);
2. If you are multi-sensor connected to the PLC,con figuration or access programmable collector, it is recommended to use the Standard ModBus-RTU protocol (see below, hex send and receive)
Standard ModBus-RTU protocol
1.The serial format 8 data bits, 1 stop bit, no parity bit. Baud rate 9600 bps, serial debugging software set to send and receive hex, the two communication intervals of at least 1000ms, the instructions in the CRC for the parity bit, two bytes. Default address 1
