Security System Using PIR Sensor

The “PIR”-based infrared sensor security system is unveiled. With the help of this sensor, we can conserve energy and manage resources efficiently while using less memory space. When an intruder or human passes through the system or place where the PIR sensor is installed, it is responsible for detecting the change in infrared radiation levels. Voltages alter in response to changes in radiation levels, which subsequently amplifies the signal and results in the production of sound. As a result, it is beneficial in many contexts and applications. When compared to the current system, this type of technology has several advantages.
