Single Channel Capacitive Touch Sensor - India


Single Channel Capacitive Touch Sensor – India

A capacitive touch sensor (Single Channel) can replace your switch in a digital circuit, which has usually a microcontroller deployed. It gives a circuit designer an option to make the circuit more appealing for the end-user, having the switch replaced.

Buy online in India the Single Channel Digital Capacitive Touch Sensor with fast shipping from Circuit Uncle (Home for Embedded / Robotics / IoT modules and Solutions). This Single channel digital capacitive touch sensor module is based on a touch-sensing IC (TTP223) (Datasheet link below). This module, just like our 4 channel capacitive touch sensor module, is easy to use and integrable with Arduino, Raspberry Pi, etc. It can though even work on its own!

The module has only 3 pins, in which two are for power supply (VCC and GND) and the other is for the digital output related to touch. Due to its ease of use, and cost-effectiveness it is very popular among students in India and they mostly make touch-based switching projects with it. Yes, you can replace your whole switch-board by utilizing it! In normal operation mode (When not being touched for 4-12 seconds, it switches to a low current consumption state automatically) it has a very low current consumption but in the fast mode its current consumption increases (Since in fast sensing mode the switching back to low current mode is not possible).

The holes in the module let it be screwed in any of the circuit boards. The LED on the module’s board indicates the state of power in it.

The initial state of the output of this module is low (A digital 0), and the touch is high (A digital 1). If you perform a search on youtube, you will find various interesting projects related to this module, and that could be a good starting reference point. So give us a chance to serve you, and buy online in India the Single Channel Capacitive Touch Sensor from us.
