3.1 Operation Mode
The MTCH9010 liquid detector offers flexibility in liquid detection by offering both capacitive and conductive detection methods.
MTCH9010 can be configured to operate with capacitive or conductive detection methods. The operation mode can be set through the digital input OP_MODE or the Enhanced Configuration.
The MODE pin must have a 0V or VDD voltage level. The following table shows
the correspondence between the pin voltage and the operation mode for the device:
| Voltage on MODE Pin | Operation Mode Selection |
|---|---|
| 0V | Conductive |
| VDD | Capacitive |
