Water leaks in appliances like dishwashers, washing machines, and water heaters can cause costly failures and safety hazards. Yet liquid detection is often an afterthought, relying on discrete sensors, analog parts, and complex firmware.
The MTCH9010 offers a better approach.
A single-chip liquid detection device with no firmware required, minimal BOM, and faster development cycles. Its compact 3×3 mm package fits tight spaces, and ultra-low power operation (<1 µA in sleep) suits always-on or battery-powered systems.
Versatile Sensing
The MTCH9010 supports both capacitive and conductive sensing modes in a single package
Capacitive: Detects water through non-conductive surfaces, ideal for level monitoring.
Conductive: Direct-contact detection for leak monitoring.
Whether you’re detecting condensation in HVAC systems, tracking fluid levels in reservoirs, or integrating early leak warnings into smart home appliances, the MTCH9010 adapts to your design.
Configurable Behavior. Reliable Operation.
-
Adjustable detection thresholds for different fluid
-
Selectable sleep intervals for power balance
-
Heartbeat output for diagnostics
For example, a smart dishwasher can use the MTCH9010’s capacitive sensing to detect unexpected water rises in standby and trigger automatic preventive actions, no firmware or tuning needed.
From Concept to Prototype in Minutes
Liquid detection doesn’t have to start with a custom PCB. The MTCH9010 Evaluation Kit includes
- Slide switches: Configure detection behaviors on the board, no programming needed.
- UART interface: Access advanced customization options.
- Capacitive pads & probe connectors: Test proximity and direct-contact sensing immediately.
- Compact layout: Self-contained design for easy bench or field testing
Evaluation Kit in Action:
A single droplet on the probe instantly lights the DETECT LED, showing fast, reliable sensing.
