Touch Sensor TTP223B, single channel, Capacitive Type Switch, use with arduino and relays module to turn ON your appliances.
The Digital Sensor TTP223B Module Capacitive Touch Switch 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.
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
