Power Supply2 ~ 5.5V DC
Output high VOH0.8 VCC V
Output Low VOL0.3VCC V
Size24 x 24 x 7.2 mm

The Digital Sensor TTP223B Module Capacitive Touch Switch is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode. Jog type the initial state is low , high touch , do not touch is low ( similar touch of a button feature ) Module can be installed in such as surface plastic, glass of non-metallic materials.

In addition to the thin paper ( non-metallic ) covering the surface of the module , as long as the correct location of the touch , you can make hidden in the walls, desktops and other parts of buttons.

Touch Sensor Interface:
  • Control Interface A total of three pins (GND, VCC, SIG), GND to ground, VCC is the power supply, SIG digital signal output pin
  • Power Indicator Green LED, power on the right that is shiny
  • Touch area Similar to a fingerprint icon inside the area, you can touch the trigger finger.
  • Positioning holes 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination.

Package Includes:
  • 1 xDigital Sensor TTP223B Module Capacitive Touch Switch

Specifications and Features:
  • Low power consumption
  • Can replace the traditional touch of a button
  • Four M2 screws positioning holes for easy installation

Approx. Rs 120 / PieceGet Latest Price

Product Details:

ShapeRound
Current Range0 ~ 36 mA
Weight30 g
Power20 Watt
Voltage5 VDC
Detection Distance2cm-400cm (0.02M - 4.0M)
Static CurrentLess Than 2 mA
Level Output5 V
High Precisionup to 0.3 cm

This ultrasonic sensor module can be used for measuring distance, object sensor, motion sensors etc. High sensitive module can be used with microcontroller to integrate with motion circuits to make robotic projects and other distance, position & motion sensitive products.

The module sends eight 40Khz square wave pulses and automatically detects whether it receives the returning signal. If there is a signal returning,  a high level pulse is sent on the echo pin. The length of this pulse is the time it took the signal from first triggering to the return echo.

Unlike the Active Buzzer, which generates a fixed tone when the power is connected, the passive needs a generated tone, as a loudspeaker does, to make it operate. This buzzer is almost identical in appearance to the Active Buzzer.

Either PWM or simply switching a digital pin on then off,  the frequency being determined by the length of the delay between switching on and off.
