Description

Water Level Measurement

This demonstration kit measures the water level with a one-channel self-capacitance electrode and a one-channel shield electrode using a Renesas capacitive touch key solution. Electrodes and liquid tanks need to be GND shielded with conductors, but the linear values can be measured with one channel of self-capacitance electrodes.

Features

  • Capacitive touch key solution with high sensitivity and high noise immunity
  • High-performance, low-power microcontroller and touch IP achieve product system control and capacitive sensor detection
  • This can also be mixed with conventional touch keys (water level measurement + touch button)

Problems with Conventional Technology (Float Type, Weight Sensor) are Solved by the Renesas Capacitive Sensor Application Demonstration Kit
