By Ferdinand Cadiland


Do you have a need for an outdoor motion sensor? Maybe you have a broken device like a motion sensor light, motion sensor sprinkler or alarm and you need replacement parts. Are you working on a project that requires motion detector sensor? If you do, then you come to the right place. Here you will find information where and how to find the right sensor for your needs.

Outdoor motion sensor devices are easy to find and are readily available in most electrical and hardware store near your area. You can even get them in online auctions like eBay and other online shops like Amazon with free delivery in some cases. You can choose with many different variations in wired and battery-powered type motion sensors.

In case you only need the sensor itself without the load like the light bulb, sprinkler or alarm, you may have a bit of a problem finding them. Manufacturers usually don't provide parts for this kind of product. So, if you accidentally break them you will have to purchase the whole unit again. But if you have an old unit that recently broke with working outdoor motion sensors on it you can just salvage the good parts.

If you are a professional electrician or you have a good knowledge in electronics and you need outdoor motion sensors for your project, you can have them through hardware store that specializes in automation equipments. These types of sensors are commonly used in industrial manufacturing plants and are usually expensive. They are used to automate the plant and also for quality control, safety and security.

For home use or if you have a limited budget, you can just buy any motion activated device like motion sensor light and utilize the sensor. In order to do this, you need to have a good knowledge in electronics to dismantle and use it for your project. If you have a motion sensor light, you can just replace the light bulb with a solenoid valve or any actuator to move something or a power relay to activate an electric motor.

Sensors used in industrial plants are available in companies that specialize in automation controls. Other product they sell includes timer, counter, relay Programmable Logic Controllers and etc. Some famous brand includes Siemens, Omron and Festo. Some factors to consider when purchasing a sensor is the range, the type of input and output, and the type of object where you intend to use it.
