there are sensor's pin define:
Red: DC5V
Black:GND
Yellow:humidity
White:temperature
KC868-A128: A1 and A2 is 0-5v dc analog input ports. A3 and A4 is 4-20mA analog input ports.
your sensor output signal is 0-5v dc. so your sensor RED and Black connect with 5V power supply. Yellow and White cable connect to A1 or A2 of A128 board.
