5pcs Capacitive Touch Dimmer Stepless Dimming PWM Contr

Feature:

1. The brightness of the light can be adjusted as needed, the selection range is wide, and the operation is simple and convenient.
2. The touch function can be realized in the case of isolation protection of media (such as glass, acrylic, plastic, ceramics, etc.), and the safety is high.
3. The application voltage range is wide and can be arbitrarily selected between 2.4 and 4.5V.
4. The application circuit is simple, the peripheral components are few, the processing is convenient, and the cost is low.
5. Anti-power interference and mobile phone interference characteristics are good. EFT can reach ±2KV or more; in the case of close-range and multi-angle mobile phone interference, the sensitivity and reliability of touch response are not affected.

Specification:

Item Type: Dimmer Module
Installation: No direct contact with copper foil, dimming through acrylic glass or plastic over 3mm.
Uses: Can control LED modules, light strips and other products. Suitable for indoor table lamp, LED lighting dimming, DIY lamp dimming to modify the best accessories.
Function: Single-line touch, using the principle of capacitive touch, sensitive touch tentacles. The default is the LED touch-infinite dimming function with switch function, dimming function and brightness memory fade-out. It lights up slowly when the light is turned on, and slowly darkens when the light is turned off, effectively avoiding eye irritation.

Mode Adjustment Matters:
1. Dimming Mode: Stepless PWM dimming
2. Wiring Method: PCB board (VCC, GND) is the power input, (LED+, LED-) is connected to the LED light positive and negative (fingerprint) for the touch area, but also for wiring (note that the wiring is not too long, the outlet After the introduction, use a small piece of copper to make the sensing area), the copper area is recommended to be about 2x3cm. The copper foil module on the board attaches one side of the copper foil to the side of the outer casing.

Instructions:
a) When the touch is touched (touch duration is less than 550ms), the lighting can be controlled. One click touch, the light is on; once click touch, the light is off. The initial brightness of the light is fixed at 90% of full brightness.
b) When the touch is long pressed (touch duration is greater than 550ms), the stepless brightness adjustment of the light can be realized. When the touch is long pressed, the brightness of the light gradually increases. When the light is released, the brightness of the light stops at the brightness corresponding to the release time. If the long press time exceeds 3 seconds, the brightness of the light does not change after reaching the maximum brightness; once again, press and hold the touch. The brightness of the light gradually decreases. When the light is released, the brightness of the light stops at the brightness corresponding to the release time. If the long time exceeds 3 seconds, the brightness of the light does not change after reaching the minimum brightness. This cycle.

Note:

Debugging Tips:If a false trigger occurs during debugging, or does not trigger, it may be caused by the following reasons:a) The touch line is too thick;b) The touch line is too long;c) copper is not big enough;d) disturbed near the power supply end of the switch;e) Touch parameter C1 is unreasonable.
