Touch Sensor Kit Golden Digital Capacitive Switch Module for Arduino

Touch Sensor:Based on the touch sensor chip TTP223B, the module is capacitive touch switch module.Normally it outputs low and it is at low power state.When you touch the appropriate location, it will output high and switch to the quick response state.When not touched for 12 seconds, it switches to low power state again.Touch Sensor (T):Based on a touch detection IC (TTP223-BA6), and the IC is in toggle mode;Power on, the module output low level and the mode is low power mode;Touch related position with finger, module will output contrast level ( ie, the original output is high, and then output is low after touch), and the mode is switched to fast mode and back to low-power mode if not touch for 12s.If the module is mounted in the surfaces of non-metallic materials such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks.Features:1. Funny and easy to use, can replace the traditional self-locking switch;2. Increase the filter circuit, the signal output stable;3. Low power consumption;4. Power supply can be 2~5.2V DC;5. Immersion gold process, long service life;6. 4 x M2 screw mounting holes.GeneralModelN/AQuantity1 setForm ColorBlue + GoldenMaterialPCB + alloySpecificationApplicationtouch switchWorking Voltage 2~5.5VEnglish Manual / SpecYesDownload Link http://pan.baidu.com/s/1o6uu5qa?qq-pf-to=pcqq.c2cPacking List1 x Touch Sensor V2.01 x Touch Sensor (T) V2.0Package Weight:0.014kg (0.031lb)Package Size:9cm x 4cm x 3cm (3.54in x 1.57in x 1.18in)
