Project 3 – PIR motion detection

The project employs the HC-SR501, a PIR sensor that is engineered specifically for the purpose of detecting the presence of humans or animals. It achieves this through the utilization of infrared signals. The sensor offers two distinct operating modes, which are Repeatable (H) and Non-Repeatable (L). These modes offer flexibility in terms of application and use. The sensor finds itself particularly well suited for a wide variety of applications, including but not limited to automatic lighting, security alarms, and industrial automation control.

One of the standout features of this sensor is its wide temperature range capabilities. This means it can function effectively in a range of different environmental conditions. In addition to this, it also boasts low power consumption. This makes it an economical choice, particularly for long-term deployment. As such, it proves to be a versatile option for any motion detection requirements, delivering...
