Motion Sensor

Smoke and Heat Detectors: Detect smoke and heat. Chapter II:Our Home Alarm SystemOur Home Alarm System:Our project’s main concern was to build a Home Alarm System using a PIC microcontroller. We started off our project by coding the Keypad, then LCD and the final touch was the sensor. We also added two types of buzzers: one to sound the alarm and the other as a key tone buzzer. The final result turned out to be the following:Figure3. For example, you can create rules to have the lights turn on when motion is detected, have your doors unlock when a smoke alarm goes off, and have a camera begin recording when a sensor is triggered.Some systems store recorded video locally on an SD card or a solid state drive, while others offer cloud storage.Locally stored video is a good choice for do it yourselfers on a budget, but you have to be careful not to Linkoverwrite video you may need later.Cloud Linkstorage makes it easy to store and access recorded video, but Linkit can cost hundreds of dollars per year depending on your subscription.Some Linksystems offer both cloud storage and local storage, Linkand some provide a dedicated storage drive that gives you DVR capabilities with time lapse recording, which makes it easy to find a video event that took place at a specific point in time.All of the systems we've Linktested feature an app that lets you use your smartphone as yourLink command center to arm and disarm the system, create rules, add and delete components, and receive push notifications when alarms are triggered.Most apps also allow you to do things like view live and recorded Linkvideo, lock and unlock doors, Linkchange thermostat settings, and silence alarms.Some apps will even use your phone's location services to Linkautomatically arm and disarm the system according to your physical location.The more expensive systems usually come with a wall mounted Linkpanel that acts as a communicationsLink hub, with a touch screen display that allows you to do everything the app does.The display lets youLink communicate with a professional monitoringLink service when an alarm is triggered and view video from any of the installed security cameras.While many systems use wireless components that are installed using double sided tape, some high end systems use components that require professional Linkinstallation.

Often this kind of job only requires a high school diploma and doesn't need long term training.

Disadvantages:One of the main disadvantages and is mainly caused by a malfunction is the generation of a false alarm where it can be triggered accidentally and thus cause unnecessary inconvenience.
