Touch Sensor capacitive touch switch module for Arduino

item 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 installationSpecification: Item Min Typical Max Unit Power supply voltage VCC 2.0 3 5.5 V Output high VOH – 0.8VCC – V Output low VOL – – 0.3VCC V 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 Response time (touch mode) – – 60 mS Size 24x24x7.2 mm Weight 2 g Interface Description:
