Fingerprint doorlock Arduino project make from Fingerprint sensor and Solenoid door lock - T0b1e/Fingerprint-doorlock ...

In this Arduino based Solenoid door lock project we use a real Solenoid Door Lock and control it with RFID and Arduino. Here a Hall Effect sensor and a magnet are used to detect the door movement.

Ultrasonic sensors are commonly used in Arduino projects for distance measurement. An ultrasonic sensor is a device that uses ultrasonic waves for distance measurement. It works on the principle of ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

In this project we have used an Arduino and Ultrasonic Sensor to determine the distance of an obstacle from the sensor. Basic principal of ultrasonic distance measurement is based on ECHO.
