Description
Introduction:
1 Channel Capacitive Touch Sesnor Module uses the touch-sensing IC TTP223 to sense the touch input thus making it easy to add capacitive touch input to your project. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. The module has single touch pad. Power the module with 2 ~ 5.5V DC and the touch pad is all active to sense the input.
Specification:
Power supply voltage(VCC): 2.0, 3, 5.5 V.
Output high VOH: 0.8VCC V
Output low VOL: 0.3VCC V
Response time (touch mode) : 60 mS
Output Pin Sink Current (@ VCC = 3V, VOL = 0.6V) : 8 mA
Output pin pull-up current (@ VCC = 3V, VOH = 2.4V) : 4 mA
Response time (low power mode) : 220 mS
Size : 24 x 24 x 7.2 mm
Pin diagram:
Features:
Control Interface: A total of three pins (GND, VCC, SIG), GND to ground, VCC is the power supply, SIG digital signal output pin
Power Indicator: Green LED, power on the right that is shiny
Touch area: Similar to a fingerprint icon inside the area, you can touch the trigger finger.
Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination.
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
Interfacing with Arduino:
Application: Embedded Systems, Digital Electronics
