This little module adopts a flexible nano pressure-sensitive material with an ultra-thin film pad to sense the exerted pressure. When pressure is applied to the measuring disc, the resistance of the sensor will change. This change in resistance is converted to a varying output voltage using an additional resistor mounted on the module to form a voltage divider. Compatible with Arduino and Arduino compatibles!
