Geekstory 10pcs TTP223B Digital Touch Sensor Capacitive Touch Switch Module Touch Sensor Switch Digital Capacitive Touch Sensor Switch DC 2~5-5V for Arduino

Description: The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode. Features: Low power consumption Power supply for 2 ~ 5.5V DC Can replace the traditional touch of a button Four M2 screws positioning holes for easy installation Power Supply Voltage VCC: Min:2.0V Typical:3V Max:5.5V Outpout high VOH:0.8VCC Output low VOL:0.3VCC Output pin sink current)VCC=3V,VOL=0.6V):8ma Output pin pull-up current(VCC=3V,VOH=2.4V):4ma Response time(low power mode):220ms Response time(touch mode):60ms Package Included: 10 X TTP223B Digital Touch Sensor
