5 Step 5: Detect Liquid

Now, the MTCH9010 is fully configured and actively reporting its detection status.

Whether using basic digital outputs or extended UART data, the board is ready for evaluation or integration into a bigger system.

Tip:
  • For capacitive sensors, touch the sensor with a fingertip or make direct contact using a water-filled object to trigger detection
  • For conductive sensors, apply a small drop of water to bridge the two sensing pads, completing the circuit and activating the sensor
  • When liquid is detected, the output LED indicates detection. The device continues its regular sleep cycle during this time
