Capacitive touch dimmer PWM

Description:
⒈ light levels can be adjusted according to need, a wide range of options, easy operation.
⒉ available under medium (such as glass, acrylic, plastic, ceramic, etc.) to achieve isolation protection case touch functionality and high security.
⒊ application voltage range, can arbitrarily choose between 2.4 ~ 4.5V.
⒋ application circuit is simple, less peripheral devices, easy processing and low cost.
⒌ anti-power interference and interference characteristics of a good phone. EFT can reach ± 2KV above; close, multi-angle cell phone interference,
Touch response sensitivity and reliability is not affected.
6. Installation: No direct contact copper, may across more than 3mm acrylic glass or plastic dimming.

7. Uses: LED modules can be controlled, with lights and other products. Suitable for indoor lamp, LED lighting dimmer, DIY lights dimming refit the best accessories.

8. Function: singlet touch, use capacitive touch principle, namely the induction sensitive fingertips. The default is a switching function, dimming function with brightness memory slowly fades the LED touch stepless dimming function. When the lights brighten slowly, slowly dimmed lights, effectively avoiding eye irritation.

9. dimming mode: PWM stepless dimming

10. Wiring: PCB board (VCC, GND) for power input, (LED +, LED-) to connect the LED sign level (fingerprint) to access the touch area, but also the wiring leads (note the wiring is not too long, outlet Available with a small piece of copper after doing the sensing area), copper area suggestions about 2x3cm. Board carrying a copper foil side of the copper foil attached to the module shell side.

11. Use

    lit a) tap the touch (touch duration is less than 550ms), you can achieve control lights off. One-click touch, lights; again tap the touch, the lamp is off. Illumination lighting of the initial luminance is fixed at 90% full brightness.
