The MCU communicates wirelessly with some RHT-1 (NA) humidity sensors and with the CCU-2 (NA) gateway via its 918.9 MHz LoRa radio. The interface with the electronically controlled fan motor consists of a 10 V DC supply from the motor to the MCU with a limited current (1 or 10 mA), tachometer pulses from the motor, and a 0-10 V control signal from the MCU to the motor.
