Abstract :
In this paper the simple microcontroller capacitive sensor is proposed. The sense oscillator is build around internal comparator with few external resistors. The output overload protection is achieved with collector voltage detection. By adding one transistor and screen behind sensing surface, increasing sensitivity and wider usage area are achieved.
