The module is a capacitive touch -type touch switch module based on the touch detection IC (TTP223B) . In the normal state, the module output is low, the mode is low power mode; when touching the corresponding position with the finger, the module will output high level, the mode switch to fast mode; when 12 seconds without touch, the mode and switch to low Power mode. You can install the module in the non-metallic materials such as plastic, glass surface, and the other thin paper (non-metallic) covered in the module surface, as long as the correct location of the touch, you can make hidden in the walls, button. The module allows you to avoid the annoyance of conventional push buttons. The module features are as follows: Jog type: the initial state is low, a touch of high -level , without touching a low level (similar to the touch of a button function) Low power consumption Power supply can be 2 ~ 5.5V DC Positive and negative can be used as a touch surface , can replace the traditional touch button 4 M2 screw positioning holes for easy installation Application display:
Action Note: first touch the touch-type touch sensor, and then a little longer hold the touch-type touch sensor , you can achieve the lamp flashing and long bright; project Minimum value Typical value The maximum value unit Power supply voltage VCC 2.0 3 5.5 V Output high level V OH - 0.8VCC - V Output low level V OL - - 0.3VCC V Output pin sink current (@ VCC = 3V, V OL = 0.6V) - 8 - MA Output pin pull current (@ VCC = 3V, V OH = 2.4V) - -4 - MA Response time (low power mode) - - 220 MS Response time (fast mode) - - 60 MS size 24X24X7.2 Mm weight 2 G
