The motion sensor is one of the most important components of the smart creation of your home. You’d be surprised how little it costs to get a basic motion sensor. You can choose from five infrared motion sensors for just one dollar each. Motion sensors also work seamlessly with popular DIY electronic kits such as the Raspberry Pi or Arduino.
Here is a brief overview of the different ways motion detectors will make your life so much easier once you adopt them.
1. Automatically turn on the front porch light
You can easily buy them online, but why buy expensive stuff when you can roll up your sleeves and make your own cheaply? Instructables user Ayush Sharma has a step by step guide on how to make a simple motion sensor easy. Total cost? $7. Obviously, this one.
2. Open the garage door automatically
Install a motion sensor at the base of your road. Connect it to your garage door opener. When your vehicle arrives, the door will open automatically. It couldn’t be easier. In fact, there is already a motion detector for garage openers. Try Genie or Chamberlain, they seem to have good reviews on Amazon.
In addition to opening the door, you can also set up a simple automation to turn on the lights as you drive, just like the lights on your front porch.
3. «Honey, I’m home!»
Is there a garage with two car compartments? Install one motion sensor in each compartment. When your car or your partner parks in the bay, the motion sensor will detect it. Then it is enough just to connect this sensor to Raspberry Pi or Arduino to do a number of things.
4. Catch sneaky criminals
Worried about your kids sneaking out of the house after curfew? Want an alarm to see if someone has broken into the restroom? Motion sensors are the easiest way to do this. Install a sensor on each door or window. Turn them on when you go to bed. Likewise, you will be alerted every time someone enters or not when they shouldn’t.
5. Energy saving
Your thermostat shouldn’t run overtime when you’re not at home. The lights should turn off when you leave the house. Your computer should also go to sleep. The motion sensor can do it all.
