Touch sensor module tact switch 1 way touch switch sensor

Touch sensor module tact switch 1 way touch switch sensor โมดูลใช้สำหรับรับค่าคำสั่งโดยการสำผัสจากผู้ใช้งาน สามารถใช้แทนปุ่มกดได้ Product Specification Supply 2.0 to 5.5V DC Response time Max About 60ms At Fast Mode, 220ms At Low Power Mode At Vdd=3v Sensor oscillator 1 Mhz Operating Temperature -20 to +70 deg C Storage Temperature -50 to +125 deg C Product Description Overview: This is a simple touch sensor module. You can use it to replace a traditional push button. Using the TTP223 touch detector IC It measures the capacitance of a metallic pad. It can detect the change in capacitance when a finger is near it. This is the same technology used in the iPhone touch screen. This little sensor can "feel" people and metal touch and feedback a high/low voltage level. Even isolated by some cloth and paper, it still can feel the touch. And the sensetivity well decrease as isolation get thick. Specifications: - 2.0-5.5V DC supply - response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V - Low power consumption - 2.0cm x 2.0cm twig module - Power indicator led to achieve inter-module combination;
