What is a capacitive touch sensor?


A capacitive touch sensor is an upgrade from the commonly used resistive sensors that relied on a change in resistance due to a change in resistor geometry due to the applied pressure. A capacitive sensor works on the principle that your finger acts as an external capacitor that changes the total capacitance of the system, which is then measured by onboard chips and converted into readable data.
