D1 D2 D3 D4: water level output interfaces (low level 0V, high level 3.7V)
I1 I2 I3 I4 : water level sensor 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 Multiple 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. )
