Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Here and example of Arduino with PIR motion sensor. The PIR motion sensor detects motion within its range and sends a signal to the Arduino board. The Arduino board processes the signal and sends a ...

The diagram below shows the orientation of the axes of sensitivity and the polarity of rotation. Note the pin 1 identifier (•) in the figure. This method starts logging with the accelerometer, using ...
