 PJU lamp with PIR sensor

Description of PJU lamp using PIR sensor

PJU lights using PIR sensors are lighting at night or active in the dark, when an object or object moves past the lights it will be detected by the PIR sensor, then the lights will turn on.

Material components:

1. 1.5 mm NYAF cable
2. MCB 1 phase
3. LDR 10 Ampere
4. PIR sensor
5. 20 watt LED light

Tool Components: 

1. Screwdriver 
2. Cutting pliers 
3. Avometer

Explanation of the components in PJU lights with PIR sensors

1. NYAF cable is a single copper cable with a fiber copper type. With this type of fiber, the NYAF cable has good flexibility so it is suitable for use in electrical panels that have many curves. NYAF cables have a voltage of 300 to 500 volts.

2. MCB (Miniature Circuit Breaker) or in Indonesian, Miniature Circuit Breaker is a device used to limit electric current and safety when there is more load. MCB works automatically disconnects the electric current when the current passing through it exceeds the nominal current on the MCB.

3. LDR is a type of resistor commonly used as a light detector or measuring the amount of light version. LDR consists of a semiconductor disk that has two electrodes on its surface. The resistance of the LDR changes with the change in light intensity that hits it.

4. Sensors are devices used to detect physical changes or quantities such as temperature, pressure, light, motion, and others. They work by converting physical energy into electrical signals that can be processed.

5. LED is short for Light Emitting Diode, which is one of the many types of semiconductor devices that emit light when an electric current passes through them. 

6. Terminal block is a term that refers to a place where the electric current stops temporarily at the end of the cable, before being connected to other cable components.

7. Electric panel box is a box that functions to accommodate and distribute electricity to various parts of a building or house. This electrical panel box is very important because it is part of the main electrical system and is often the center of the electrical installation.

How PJU Lights Work with PIR Sensors: 

1. When the MCB is raised, the LDR is in a state of readiness 

2. If at night the LDR is active 

3. If the PIR sensor detects a passing object, the PJU lights will turn on 

4. If the PIR sensor does not detect a passing object, the PJU light does not turn on.
