Home-Security-System MPCA college project using PIR, temperature, and LDR sensors. Detects motion, tracks temperature, and measures light intensity. Built with Arduino for real-time environmental ...

PIR module usually requires an initial warm-up period for the sensing elements to come up to the operating mode. This usually takes not less than 30 seconds. So a 30 seconds delay is intentionally ...

The real-time PIR sensor in Proteus senses the motion of a particular area. As Proteus is the EDA, to show the motion, a TestPin is present on the sensor. I used the toggle pin here to indicate the ...

The PIR module actually consists of a pyroelectric sensor (looks like an old metal transistor with a black window on the top), which generates energy when exposed to heat, and it’s tied in closely ...

The massive quantity of electricity gets used in lights through roadways in India. Still, roadways remain empty for nearly all of the day after at night, with a handful of cars passing during the ...

How it works: When something triggers the sensor, the Arduino records that moment as triggerTime in Line 23, and compares it with the current time based on conditions in lines 26, 29, and 34.
