The name itself states that it is the sensor which works on the Hall Effect. It can be defined as when a magnetic field is brought close to the current carrying conductor (perpendicular to the direction of the electric field) then a potential difference is developed across the given conductor...

How to use the HC-SR04 Ultrasonic Sensor HC-SR04 distance sensoris commonly used with both microcontroller and microprocessor platforms like Arduino, ARM, PIC, Raspberry Pie etc. The following guide is universally since it has to be followed irrespective of the type of computational device used. P...
Output and Ground as shown in the pin diagram above. Since the output pin is 3.3V TTL logic it can be used with any platforms like Arduino, Raspberry,PIC, ARM, 8051 etc..
Another way would be to use an ultrasonic distance sensor to detect the distance of the eyelids relative to itself. This is a feasible way. I came up with this only after I ordered the PCB with the hall sensors, so I stuck with that. ...
Please refer to this link for;IR Sensor Module Interfacing with Microcontroller – Arduino, PIC. Advantages Theadvantages of IR sensorinclude the following It uses less power The detection of motion is possible in the presence or absence of light approximately with equal reliability. ...
can be easily interfaced with microcontrollers likeArduino. For this, an Arduino microcontroller board for processing, a Hall effect water flow sensor, a 16×2 LCD display, and Breadboard connecting wires are required. The sensor is placed at the water source inlet or at the opening of the ...
An accelerometer is a onetype of sensorand it gives an analog data while moving in the direction of X, Y and Z. These directions depend on the type of sensor. The diagram of accelerometer is shown below. This sensor consists of arrow directions, if we tilt the sensor in one direction,...
ultrasonic sensor the sound waves will reflect in the form of echo and generates an electric pulse. It calculates the time taken between sending sound waves and receiving the echo. The echo patterns will be compared with the patterns of sound waves to determine the detected signal’s condition....
