Project Scope(for reference): 1.With the optocoupler + bi-directional thyristor can be completed touch fluorescent lamps and other smart home projects 2.With the optocoupler + delay + bidirectional thyristor stairs to complete the touch lamp Features: Low power consumption Power supply: 2 ~ 5.5VDC This module can replace the traditional touch button Four M2 screws positioning holes for easy installation Specification: Power supply voltage VCC: 2.0--5.5 V(Typical 3V) Output 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): 4 mA Response time (low power mode): 220 mS Response time (touch mode): 60 mS Size: 24x24x7.2 mm Weight: 2g Package Include: 10 TTP223B Switch Module Digital Touch Sensor
Product Features
- This is the "momentary" variety of the touch sensor - touch and it turns on, release and it turns off.
- Positive and negative can be used as a touch surface,can replace the traditional touch button.
- Four M2 screws positioning holes for easy installation.Module can be installed in such as surface plastic, glass of non-metallic materials.
- In addition to the thin paper ( non-metallic ) covering the surface of the module , as long as the correct location of the touch , you can make hidden in the walls, desktops and other parts of buttons.
- 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.
