There are 1 incomplete or pending task to finish installation of Semantic MediaWiki. An administrator or user with sufficient rights can complete it. This should be done before adding new data to avoid inconsistencies.1. How does it work
Touch Sensor is use in a one of HMI (Human Machine Interface)
- Instead of using mechanical switch, using the finger touch on the surface
Three different methods
- Capacitance switch
- The electrode can be placed behind a non-conducted panel
- Detect the capacitance change
- Resistive touch switch
- Two electrodes can be shorted by finger touch
- Detect the short circuit
- Piezo touch switch
- By pushing/bending Piezo material, it generates the voltage
- Detect the voltage change
TSC or Touch Sense Controller peripheral is based on the Capacitance switch
- When human touch the surface of the sensor area, the capacitance changes
