Wiring the FunHouse to the water sensor is pretty straight forward. The only tricky bit we are doing here is we are using 2 JST ports to read the sensor. One of the JST ports is used for reading the sensor and the other port is powering the sensor with its signal wire. This is so the sensor isn't on all the time, which can lead to electrolyzing the traces fairly quickly.
Since this is a water sensor and we're dealing with electronics, we recommend connecting a servo extension cable between the JST cables and the sensor.
- Connect the white wire from the JST connector of A0 to the positive or + pin on the water sensor.
- Connect the black wire from the JST connector of A1 to the ground or - pin on the water sensor.
- Connect the white wire from the JST connector of A1 to the signal or S pin on the water sensor.
- Leave any remaining wires unconnected.
Attach the sensor to the side of the bowl. If it has trouble sticking due to the curve in the bowl, you can add more adhesive.
You'll want to align the bottom edge around where you would want to be alerted, so if your pet likes it changed more frequently and doesn't drink much, you may want to mount it a bit higher.
