정전식 터치 센서를 가지고 있는 제품으로 손가락을 터치하여 LED 조명의 디밍(밝기 조절)이 가능한 제품입니다.
3.3V 시스템과 사용이 가능합니다.
특징
Touch dimming module can achieve LED lighting touch switch control and brightness adjustment. Has the following features and advantages:
⒈ light brightness can be adjusted according to need, choose a wide range, easy to operate.
⒉ can have a medium (such as glass, acrylic, plastic, ceramics, etc.) isolation protection to achieve the case of touch, high security.
⒊ application voltage range, can be between 2.4 ~ 4.5V arbitrary choice.
⒋ application circuit is simple, less peripheral devices, processing convenience, low cost.
⒌ anti-power interference and mobile phone interference characteristics. EFT can reach ± 2KV or more; close, multi-angle mobile phone interference,
Touch response sensitivity and reliability are not affected.
6. Installation: no direct contact with copper foil, you can across more than 3mm acrylic glass or plastic dimming.
7. Uses: control of LED modules, lights and other products. Applicable to indoor table lamp, LED lighting dimming, DIY lights dimming the best accessories.
8. Function: single-line touch, the use of capacitive touch principle, sensitive sensor tentacles that can be. The default is a switch function, dimming function, with brightness memory gradually darken the LED touch stepless dimming function. Turn on the lights slowly turn on, turn off the lights slowly dim, effectively avoid the eye irritation.
9. Dimming mode: stepless PWM dimming
10. Wiring: PCB (VCC, GND) for the power input, (LED +, LED-) for the LED lights are positive and negative (fingerprint) for the touch area, but also wiring leads (Note that wiring is not too long, outlet After the referral with a small copper to do induction area), copper area recommended 2x3cm or so. The copper foil module comes with a copper foil on the side of the housing.

11. How to use
A) Click to touch (touch duration less than 550ms), you can achieve the light off control. One click touch, light; once again click touch, light off. The initial brightness of the light is fixed to 90% of full brightness. B) Long press touch (touch duration greater than 550ms), can achieve light stepless brightness adjustment. A long press the light, the brightness of the light gradually increased, the brightness of the light when the release of the corresponding time to release the brightness, if the long press time of more than 3 seconds, then the brightness of light to reach the maximum brightness no longer change; The brightness of the light gradually decreases, the brightness of the light when the release of the corresponding time to release the brightness, if the long press time of more than 3 seconds, then the brightness of light to no longer change the brightness
The So loop. 12. Tips for debugging
If there is a false trigger during debugging, or if it does not trigger, it may cause the following:
A) the touch line is too thick b) the touch line is too long c) copper is not big enough d) close to the switching power supply side of the interference e) touch parameter C1 unreasonable
Technical features:
TI Touch input corresponds to LED lighting control output. There are four kinds of functions that can be selected by the T1 and T2 pins before power is applied
State to decide. details as follows:
⒈ T1 = 1, T2 = 1 corresponds to: no brightness memory suddenly burst dark LED touch stepless dimming function
