IR Sensor Module: IR sensors (Infrared sensor) are modules which detect the presence of objects before them. If the object is present it give 3.3V as output and if it is not present it gives 0 volt.

Circuit Diagram and Explanation: In this Raspberry Pi Finger Print sensor interfacing project, we have used a 4 push buttons: one for enrolling the new finger pring, one for deleting the already fed ...

To read the data from the IDT FS2012 flow sensor module, the raspberry pi need to set up the I2C communication. In this tutorial, the WiringPi library which is the Cpp library for raspberry pi is used ...

The Raspberry Pi 5 was recently introduced with the Broadcom BCM2712 CPU and the RP1 chip handling I/Os designed in-house by the Raspberry Pi just like they did for the RP2 (RP2040) microcontroller, ...

The Python code in the Code 1 block below will monitor pin 16 of the Raspberry Pi and print “Motion Detected” to the screen when the key-fob button is pressed. After the motion detector reset time ...

Ultrasonic sensors offer advantages in longer range and non-contact detection compared to IR sensors. IR sensors can be affected by ambient light and surfaces, while ultrasonic sensors work well in ...
