Product description
This is an 8 channel capacitive digital touch sensor module made using ic ttp226. This is designed for replacing traditional button switches with fixed pad size which is able to detect stable touch of human body. Features: -Low power consumption -wide operating voltage range -stable touch detection of human body -on-board touch indication LEDs -three modes of operation: Direct mode, serial interface mode, key matrix mode -outputs can be selected as active low or active high.
The TTP226 is an 8-Channel Touch Sensor, meaning it has eight touch pads. Whenever a capacitive load such as human hands is brought in proximity with the sense pad, the sensor then senses the change in capacitance and activates the switch. Custom sense-pads can be made from nearly any conductive material and these sensors can detect touch through thin layers of non-conductive materials such as glass, plastic, fabric or even wood. Each Touch pad has its respective output pin, when the user touches a pad the corresponding output pin will go high. It is very easy to interface with micro controllers like Arduino and Raspberry Pi to control different applications as a switch. It can be used in home automation, motor control, Relay control basically it gets rid of the push button troubles.
Specifications:
- Operating Voltage: 2V-5.5V
- Startup Calibration Delay: 0.5 Sec
- Simple to Use, Auto Calibration
- Output Status Indicator LED
- Output can configured be Active High or Low
- Output Mode can be configured to Toggle or Momentary
- Output can be directly connected to Microcontroller’s Input pins
Product Description
To connect it with Arduino connect Pins VCC and GND to power up the module. Connect the Output pins to any Digital I/O pins of the Micro controller Board. Whenever the user touches the pad the corresponding LED will light up and the pin will go High. You can read this signal by using Digital Read command.
