Four Channel Capacitive Touch Sensor – India

A capacitive touch sensor (Four/Multi-Channel) can replace several of your switch in any digital circuit. This sensor module is usually deployed with a microcontroller. It gives a circuit designer an option to make the circuit more appealing for the end-user, having several switches replaced.

Project Idea: A  Capacitive Touch Sensor Based switchboard!

Here you can buy the Four-Channel Capacitive Touch Sensor in India. Order multiple products and save per-item shipping cost in India. Local Pickup is also available in Delhi-NCR.

SAVE MORE! By buying the combination instead, see below for this offer.



Buy in India the four-channel capacitive touch sensor module at Circuit Uncle, and get it delivered at your doorsteps with ultra-fast shipping. The technical name of this module is TTP224. This module is having a very low power consumption (in low power mode), and has a total of 6 pins. 2 pins are reserved for the power supply and the other 4 are for the touch-based output. Another sensing mode this module supports is the Fast mode, where its response time is less, but the current consumption will be increased. All the touchpads are always active to sense any touch. When you will bring your fingers near the touchpads, the module will sense a change in capacitance, which could be sensed through the digital/analog pins of the Arduino as a voltage drop. Although the output behavior could be changed. There are Output Status Indicator LEDs already soldered on this, which enable you to see if the touchpad is working or not.  Output Mode can be configured to Toggle or Momentary.

This module has a buit in the voltage regulator, and it can be set to enable or disable by the REGEN pin. If the REGEN pin is opened or connected to VDD, the regulator is enabled and vice versa.

It can be easily interfaced to Arduino, and it can work even without utilizing a microcontroller! So make circuits with this sensor and replace all the old switches.

Output mode could be changed (By using TOG, OD, AHLB pad pins). To learn more about how to control properly this Four-Channel Capacitive Touch Sensor you can refer to the datasheet link below.


  • Low power consumption
  • Advanced Pins breakout, so that the output mode and working mode select-able.
  • Power supply for 2 – 5.5V DC
  • This module can replace the traditional touch of multiple buttons
  • Tightening screws positioning holes at corners for easy installation, and power indicator: Green led.
  • Control interface: A total of 6 pins (GND, VCC, O1, O2, O3, O4).
  • PCB Size: 35×29 mm
  • Startup Calibration Delay: 0.5 Sec
