capacitive sensor circuit diagram

The purpose of this circuit is to animate shop windows using a capacitive sensor positioned behind a postcard-like banner. The card is placed against the glass inside the shop window, allowing visitors to activate the relay by placing their hand on the card from the outside. This circuit is particularly suited for toy shops, as it can activate model trains, small electric racing cars, lights, and more. Additional applications are left to the user's imagination. It can be adopted to enhance the impact of shop windows during the upcoming Christmas season.

This circuit utilizes a capacitive sensor, which detects changes in capacitance caused by the presence of a human hand. When a visitor places their hand on the card, the sensor is triggered, sending a signal to activate a relay. The relay acts as a switch, enabling the control of various devices such as lights, motors, or other electronic components, depending on the desired effect.

The design typically includes a capacitive sensing module, which can be configured to adjust sensitivity levels to avoid false triggers from environmental factors. A microcontroller may be incorporated to process the sensor input and control the relay output, allowing for more complex animations or sequences.

Power supply requirements for this circuit can vary based on the components used, but it is essential to ensure that the relay is rated for the load it will control. The circuit may also include additional features such as LED indicators to show when the system is active or in standby mode.

This setup is ideal for seasonal promotions or events, as it draws attention to the shop window and engages potential customers. By customizing the animations or effects triggered by the circuit, shop owners can create a memorable shopping experience that encourages foot traffic and increases sales during peak seasons.The purpose of this circuit is to animate shop-windows by means of a capacitive sensor placed behind a post-card-like banner.
