How To Change Outdoor Light Motion Sensor

Outdoor light motion sensors are an important part of home security. They can detect movement and turn on the lights, which can deter burglars and other criminals. However, motion sensors can malfunction over time, and it is important to know how to change them when they do.

There are a few essential aspects to consider when changing an outdoor light motion sensor. These include:

The type of motion sensor
The location of the motion sensor
The wiring of the motion sensor
The settings of the motion sensor

In this article, we will discuss each of these aspects in detail. We will also provide step-by-step instructions on how to change an outdoor light motion sensor.

Before you begin, it is important to turn off the power to the light fixture. You can do this by turning off the circuit breaker or fuse that powers the light.

### 1. The Type of Motion Sensor

There are two main types of outdoor light motion sensors: passive infrared (PIR) sensors and microwave sensors. PIR sensors detect changes in infrared radiation, which is emitted by all objects that have a temperature above absolute zero. Microwave sensors detect changes in microwave energy, which is a type of electromagnetic radiation that is emitted by all objects that are moving.

PIR sensors are less expensive than microwave sensors, but they are also less sensitive. Microwave sensors are more sensitive than PIR sensors, but they are also more expensive.

### 2. The Location of the Motion Sensor

The location of the motion sensor is important because it will determine the area that the sensor can cover. The sensor should be placed in a location where it will have a clear view of the area that you want to protect.

If the sensor is placed too close to the light fixture, it may not be able to detect movement properly. If the sensor is placed too far away from the light fixture, it may not be able to turn on the lights when movement is detected.

### 3. The Wiring of the Motion Sensor

The wiring of the motion sensor is important because it will determine how the sensor is connected to the light fixture. The sensor should be wired according to the manufacturer's instructions.

If the sensor is not wired properly, it may not work properly. It is important to make sure that the wires are securely connected to the sensor and to the light fixture.

### 4. The Settings of the Motion Sensor

The settings of the motion sensor are important because they will determine how the sensor behaves. The settings can be adjusted to change the sensitivity of the sensor, the time that the lights stay on after movement is detected, and the range of the sensor.

It is important to adjust the settings of the motion sensor to meet your specific needs. The settings can be adjusted using the controls on the sensor or using a remote control.
