Capacitive Touch Evaluation System for RX130
The RX130 capacitive touch evaluation system makes it easy for users to evaluate touch solutions offered by Renesas. You can start evaluating immediately out of the box...
Overview
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
