Solenoid vae water pump motor automatic control Interface descrtion: VCC :Power of positive(DC 5V +) GND :Power of negative(DC 5V -) O1 O2 O3...O8 : water level output interfaces (2.54MM Pin;low level 0V, high level 3.7V) Leve1Leve2...Leve8 : water level r interfaces (2P XH2.54) Wiring diagram : Make the probe(Need to be purchased separately): 1 Prepare 2PCS(or more) XH2.54MM wires (You can prepare this kind of wire by yourself, or buy it from our shop) 2 Multle wires can be spliced to lengthen the probe length. (Please do waterproof treatment at the splicing.) 3 Please cut the female interface short and keep a distance of 5-10MM (This prevents water droplets from sticking to the probe. )
