Webb14 apr. 2024 · The capacitive proximity sensor alarm circuit is a simple circuit that uses a transistor as an oscillator to operate a relay. The circuit works by using the transistor as an HF oscillator, whose frequency is determined by the JAF1 choke and the parasitic capacitance of a metal dish connected to its collector. WebbCapacitive sensing technology is not sensitive to sunlight or artificial light effects. The STM8T143 offers a much lower consumption (12 μA range versus 100 μA range) and a small form factor (DFN8 2*3*0.65 mm). Lastly, there is no need for a clear opening on the bezel to let light pass through. WebbIf you need to sense proximity, a light sensor might work. If you want to measure pressure, a pressure sensor could do the trick. Capacitive sensors are wildly unstable, and require constant calibration, unless they are in a perfectly controlled environment. toilet duck data sheet uk
