Apassive infrared sensor(PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications. What is SAP ...
Keep in mind that the resistance varies with light intensity, so the measurement should be taken in consistent lighting conditions. 12. What is the dark resistance of an LDR? The dark resistance of an LDR is its resistance when there is no light falling on it. This value can range from ...
The Arduino Leonardo looks like the UNO and is in many ways similar to it. But because it is based on the ATmega32u4, it has an advantage with built-in USB communication. This allows it to emulate computer peripherals like mice and keyboards, making it especially useful for projects involvin...

Motion sensors can control lighting and other devices based on occupancy. Lights, for instance, can automatically turn on when someone enters a room and turn off when no motion is detected. This efficient usage of energy not only lowers utility bills but also supports environmental sustainability....
