พร้อมส่ง-Digital Capacitive Touch Sensor Module

Touch Sensor
โมดูลใช้สำหรับรับค่าคำสั่งโดยการสำผัสจากผู้ใช้งาน สามารถใช้แทนปุ่มกดได้

Feature
- Low power consumption, can replace the traditional key, 4 x M2 screw holes, easy for operation
- Operating voltage: DC 2.5~5.5V; VOH 0.8VCC V; VOL / 0.3VCC / V; Response time: 220mS (at mode of low power consumption), 60mS (quick speed mode)
- 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
