Approx. Rs 85 / PieceGet Latest Price

Product Details:

Current Range0 ~ 36 mA
Weight30 g
Power20 Watt
Detection Distance2cm-400cm (0.02M - 4.0M)
Static CurrentLess Than 2 mA
Level OutputDC 5 V
High Precision0.3 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 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.

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

MC38 Wired Door Window Sensor can be used as a door or window security system. It produces the signal when moved away from each other which can be fed to the microcontroller to perform the desired action as per requirement.


This sensor suitable to use for trigger alarm or ON/OFF light inside a cupboard sliding door. This wired sensor is trigger by the magnet. When the magnet is closed by, the circuit is closed or open if the magnet far from the sensor.


Features:

  • Easy to install
  • Strong concealment
  • Magnetic sensor alarm, control the switch of the circuit via the built-in magnet
  • Alarm when someone intrudes into your places
  • Can be used in places like apartment, hotel, office, etc.
  • Ideal for residential or commercial use.
  • Designed to do embedded in the door or window frame.

Note: 

  • Normally closed: When the magnet together, the circuit is conductive( light on ); when the magnet separate, the circuit is not conductive ( light off ). 
  • For example: Install on the door, close door light on. open door light off.
