Hukseflux SR30-D1 (Modbus RTU)
Last modified:
Set the bus address on the sensor (see sensor documentation).
If the device is the last one on the RS485 bus, terminate the bus with a 120 Ω terminating resistor.
Various Modbus devices can only be queried together if the serial communication parameters are identical (baud rate, number of data bits, parity, stop bits).
Pyranometers can be used to measure irradiance either in horizontal or module plane.
