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. )
