Me Touch Sensor

The Makeblock Me Touch Sensor is a capacitive touch sensor built on the TTP223 - BA6. It gets triggered when you touch it with your finger. You can also connect the 'TOUCH' pinhole to metal structures and trigger the sensor by touching the metal. The sensitivity is set at a proper level, but if you have special needs, you can change the values of R3 and C4. After power - on, it takes 0.5 seconds for self - calibration, so don't touch the sensor during this time. Key features include contactless touch trigger, self - adapting sensitivity, 16mm interval M4 mounting holes compatible with Makeblock beams, 2.54mm pin holes for Dupont wire connection, easy wiring with a 6P6C RJ25 interface, and an Arduino library for simple programming. The sensor runs on a rated voltage of 5V and has dimensions of 24 x 48 x 16 mm (length x width x height). You can download the Arduino Library, and if you have any questions or need technical support, post them on the Makeblock forum.

Using the Makeblock Me Touch Sensor is quite easy. First, connect it to your project. You can use the 2.54mm pin holes with Dupont wires or the 6P6C RJ25 interface for wiring. If you want to trigger it, you can simply touch it with your finger. Or, connect the 'TOUCH' pinhole to a metal part and touch the metal. After you turn on the power, wait for 0.5 seconds before touching the sensor because it's doing a self - calibration. If the sensitivity doesn't work for your project, you can try changing the values of R3 and C4. For maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures or humidity.
