ALMOCN 10PCS TTP223B Digital Touch Switch Module Capacitive Sensor Switch DIY DC 2~5.5V for Arduino Raspberry Pi
Description
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 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 Touch Sensor Interface: Control Interface: A total of three pins (GND, VCC, SIG), GND to the 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. Package Include: 10 TTP223B Switch Module Digital Touch Sensor
Features:
- TTP223B Chip, Low power consumption, and power supply is DC 2-5.5V; Green LED Indicator, and it is bright when power on right; Control port: GND, VCC, SIG; Both positive and negative can be used as a touch surface, and replace the traditional touch of a button.
- Four M2 screws positioning holes for easy installation.Module can be installed in such as surface plastic, glass of non-metallic materials.
- In the normal state, the module output low, low power consumption, but when a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.
- 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.
- Size: 24 x 24 x 7mm/9.45 x 9.45 x 2.76inch (L x W x H).
