About this item

The ELECROW Crowtail‑Touch Sensor is a capacitive touch input module designed for easy integration into embedded systems and DIY projects. Utilizing the TTP223‑B touch IC, this sensor can detect a human finger within a range of 0 to 3 mm. This feature allows the sensor to be placed under non‑metallic surfaces such as glass or paper, making it ideal for applications requiring waterproof or concealed touch interfaces. The module operates with a wide voltage range of 2.0 to 5.5V DC and offers a low power consumption, making it suitable for battery‑powered projects. The sensor's response time is approximately 60 milliseconds in fast mode and 220 milliseconds in low power mode at a supply voltage of 3V. Its compact dimensions (20.0 × 20.0 × 6.8 mm) and smooth panel mount design facilitate easy installation into various enclosures. Compatible with the Crowtail ecosystem, the sensor can be seamlessly connected to development boards like Arduino, Raspberry Pi, and ESP32 using the included 4‑pin cable. This versatility makes it an excellent choice for creating touch‑sensitive buttons, interactive displays, and other user interface elements in embedded applications.
