Rebar Detector TEM 620-HX Detector Rebar TEM 620

Power: 7-24VDC

Standard MODBUS communication format, on-board 8-bit DIP switch to set the communication address and baud rate, MODBUS function code 04 to read data, read up to two channels of total temperature and humidity a total of four data.
Example Send: (01) + (04) + (00 00) + (00 04) + (F1 C9)
Sensor Address + Function Code + Register First Address + Number of Read Bytes + CRC16 Checksum
(01) + (04) + (08) + (02 46) + (00 FD) + (00 00) + (00 00) + (EF C4)
Sensor Address + Function Code + Number of Return Bytes + Humidity 1+ Temperature 1+ Humidity 2+ Temperature 2 + CRC16 Calibration
Humidity 1 (0246) Hexadecimal data is converted into 582 decimal system, the actual humidity of 58.2%;
Temperature 1 (00FD) 16 hexadecimal data converted to 253 decimal system, the actual temperature of 25.3 degrees Celsius;

Sensor 2 is not connected, so the data read is 0;
