Arduino Code for Speed Sensor In general, the following code makes Arduino to measure the speed of the moving object using two IR sensors and display the object speed in the I2C 16x2 LCD display. When ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

The equipment circuit design enables each customer to conne ct this home security system to a distant network using a piezoele ctric buzzer, an LCD board, and a PIR sensor at residences and workplaces ...

As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion ...
