The PIR motion sensor light wiring diagram is shown below. The basic idea is to amplify the output signal from the PIR sensor to control the relay, which, in turn, switches the bulb on or off. The ...

Circuit Diagram for Pulse Sensor Module. The circuit diagram of the Pulse sensor module is shown below. The first important part of this circuit is the 10uF filter capacitor followed by the Green LED ...

This light sensor switch circuit allows the automatic connection of a lamp when the light is low (at nightfall) and will maintain the lamp ON for a certain period of time. This time can be adjusted ...

Complex photonic architectures integrated into a single silicon chip require real-time control to keep each device at the desired working point. With this aim, non-invasive optical sensors are an ...
