How to Wire a PIR Sensor to a Transformer

A PIR sensor (passive infrared sensor) is a device that detects the presence of heat, which is emitted by people and animals. PIR sensors are often used in security systems to detect intruders. In this tutorial, we will show you how to wire a PIR sensor to a transformer. ### Materials * PIR sensor * Transformer * Wire * Electrical tape * Screwdriver ### Steps 1.

Disconnect the power to the transformer.

2.

Locate the terminals on the transformer.

The terminals are usually marked with "V", "N", and "L". 3.

Strip the ends of the wires.

Strip about 1/2 inch of insulation from the ends of the wires. 4.

Connect the wires to the transformer.

Connect the black wire from the PIR sensor to the "L" terminal on the transformer. Connect the red wire from the PIR sensor to the "N" terminal on the transformer. Connect the green wire from the PIR sensor to the "V" terminal on the transformer. 5.

Secure the wires with electrical tape.

Wrap the wires around the transformer with electrical tape to secure them in place. 6.

Reconnect the power to the transformer.

### Testing the PIR Sensor Once you have wired the PIR sensor to the transformer, you can test it to make sure it is working properly. 1.

Turn on the power to the transformer.

2.

Move your hand in front of the PIR sensor.

The PIR sensor should detect the heat from your hand and turn on. 3.

Move your hand away from the PIR sensor.

The PIR sensor should turn off. If the PIR sensor is not working properly, you may need to adjust the sensitivity. The sensitivity of the PIR sensor can be adjusted by turning a screw on the sensor. ### Conclusion In this tutorial, we showed you how to wire a PIR sensor to a transformer. PIR sensors are a great way to add security to your home or business. By following these steps, you can easily add a PIR sensor to your own security system. ## Additional Information * For more information on PIR sensors, you can visit the following websites: * [PIR Sensor Tutorial](https://www.circuitbasics.com/pir-sensor-tutorial/) * [PIR Sensor Datasheet](https://www.vishay.com/docs/81105/pir501.pdf) * If you are having trouble wiring your PIR sensor, you can contact a qualified electrician for help.
