A Motion Sensor Light is an automatic lighting system that turns ON when it detects movement in its range and switches OFF after a certain period of inactivity. This system is widely used for energy conservation, security, and convenience. The circuit described here uses a PIR (Passive Infrared) sensor, a BC547 transistor, a relay, and […]

PIR Motion Sensor Circuit with 555 Timer IC
Let’s designing a PIR motion sensor circuit that uses a Passive Infrared (PIR) sensor to control a buzzer through a 555 timer for motion detection applications. Here’s a step-by-step guide to creating this circuit: Working Principle of PIR Motion Sensor: A Passive Infrared (PIR) motion sensor detects motion by sensing changes in infrared radiation. Here’s […]
What is a Sensor? Types of Sensors, Classification & Applications
Let’s see various types of sensors within their classification and Applications. A sensor is a device or component that detects changes in its environment and converts those changes into an electrical signal or another form of readable data. Sensors are used in various applications to monitor, measure, or control processes, equipment, or environmental conditions. They […]
