The circuit was specially designed for shop windows animation as it makes use of a capacitive sensor that is triggered by touch control system. BC337 – a small signal NPN Silicon AF medium power ...

We’re excited to share that we build a smart touch sensor switch module, made to bring modern features to your products or devices without the hefty price tag. This project is covered by the following ...

How to connect the TTP223 touch sensor with ESP32 to control relays. explained the circuit and source code in detail. How to connect the TTP223 touch sensor with ESP32 to control relays. explained the ...

This is a very simple touch sensor switch that is build with the 555 timer IC. You just need to touch the metal plate and the relay gets energised and is kept in this state for about 100 seconds, then ...

This is a touch sensing circuit based on the principle of capacitive voltage division. It employs differential measurement techniques, which effectively reduce interference from environmental noise, ...

The KY-038 sound sensor pinout has 4 pins: VCC, GND, Digital Out, and Analog Out. We can either use the AO pin as an output for analog reading or the DO pin as an output for digital readout. The Sound ...

The DHT22 temperature and humidity sensor is a versatile and cost-effective sensor used to measure ambient temperature and humidity for a wide range of applications. It is based on a digital signal ...
