TheHS-S43A, Touch Sensing Sensor is a touch switch module based on the principle of capacitive sensing. The human body or metal touching the gold-plated contact surface of the sensor will be sensed. In addition to direct touch with the metal surface, contact with a certain thickness of plastic, glass and other materials can also be sensed. The sensitivity of the induction varies with the size of the contact surface and the thickness of the covering material. The module has two output modes, which can be switched by changing the welding jumper.
Touch Sensing Sensor is a short-circuit point on the module for changing the mode. Solder the two short-circuit points above, and the module mode will switch to switch mode. At this time, it can be used to make a desk lamp with less complicated touch control. Short-circuit the two short-circuit points below, and the module mode will switch to button mode. At this time, it can be used to replace the physical button. Note: When using, the module needs to be at a certain height from the fixed surface to avoid signal errors caused by contact. Do not hold the touch sensor directly, which will cause the back capacitor to heat up to avoid burns.
Features:
- Capacitive sensing technology for high responsiveness
- Gold-plated contact surface for reliable touch detection
- Mode switch via solderable jumper (switch or button)
- Detects touch even through non-metallic covers
- Compact and easy to integrate into projects
- Ideal for replacing mechanical buttons or touch-controlled devices
