However, when an object is in front of the sensor, the infrared light will be obstructed and reflected back to the detector. When there is no object in front of the sensor, the emitted infrared light will be received by the detector directly. The emitter sends out infrared light while the detector receives infrared light. The motion sensor is made up of two parts, an emitter, and a detector. This change in resistance triggers the electronic switch to turn on or off, depending on the specific design of the sensor. When the surrounding light level changes, the resistance of the photoresistor also changes. It basically consists of a light-sensitive element (usually a photoresist switch) and an electronic. The working principle of a motion sensor is relatively simple. When choosing a light bulb for use with a motion sensor, it is important to consider the type of energy required to operate the bulb as well as its long-term efficiency. So overall, it seems that both incandescent and fluorescent/LED bulbs can be used with motion sensors, and that smart bulbs are also generally compatible with these devices. However, most modern light bulbs should be able to work well with the most common types of motion sensors. Overall, whether or not a light bulb is compatible with a motion sensor will depend on the type of technology used in both devices. However, if you are looking to build your own system from scratch, then there are also many third-party smart bulbs and motion sensors that you can purchase separately and connect together yourself. Some home automation systems come with built-in support for connecting these types of devices together. If you are using a smart bulb, such as those that are connected to the Internet or can be controlled using your smartphone, you may be able to use it with a motion sensor. Motion sensors can also be used with both types of light bulbs to automatically turn them on or off when someone enters or leaves the room. As such, the difference between these two types of light bulbs lies primarily in the type of energy they require to operate as well as their long-term efficiency. Incandescent light bulbs emit light by heating a filament until it glows, whereas fluorescent and LED lights use an electric current to excite mercury vapor or simply illuminate power semiconductors with electricity. Light bulbs can be divided into two main types - incandescent and fluorescent/LED. Does a motion sensor light need a special bulb? They are used in a wide range of applications including security systems, people counting devices, and burglar alarms. Motion sensors are devices that are triggered when movement is detected.
