Microchip MTCH9010 Liquid Detection Turnkey Device

A complete liquid detection solution for modern designs

Microchip’s MTCH9010 Liquid Detection Turnkey Device delivers a compact, low-power solution for accurate liquid detection across multiple applications. The device integrates capacitive and conductive sensing in a single package, allowing it to detect oils, fuels, water, and ionic liquids without extra components or custom firmware.

It provides digital output for basic detection and UART output for advanced real-time monitoring, supporting plug-and-play deployment or integration into complex systems.

It now supports Zephyr® RTOS and is part of the Zephyr mainline offering developers greater flexibility and faster integration. Whether you prefer working within Microchip’s MPLAB® development environment or an open-source framework like Zephyr, the MTCH9010 gives you the freedom to choose the toolchain that best fits your workflow.

Features

  • Dual sensing modes: capacitive for oils and fuels, conductive for water and ionic liquids
  • Digital output and enhanced UART output for flexible monitoring
  • Heartbeat pin for system status verification
  • Pin-configurable setup for threshold, sleep period, sensing mode, and system lock
  • Ultra-low-power operation with configurable sleep cycles down to 1µA
  • Wake-on-request mode for power efficiency

Applications

  • Home appliances and leak detection, such as washing machines and water heaters
  • Industrial liquid monitoring, pipelines, and spill detection
  • Battery-powered remote sensors for IoT and smart agriculture
  • Medical fluid monitoring in IV lines, catheters, and dialysis systems
