Door and window sensors make up the backbone of any home security system. If a door or window gets opened or breached when the alarm is on, the sensor sends a signal to the main control panel, triggering an alarm. There are different types of door and window sensors, though they all perform basically the same function.
Home security systems are comprised of a few different devices that all work together to form a layers of protection in around your home. Window sensors make up the backbone of any home security system and monitor which doors and windows are opened and closed. There are a few different types of sensors.
A motion detector attached to an outdoor, automatic light.
A motion detector is a device that detects moving objects, particularly people. Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. They form a vital component of security, automated lighting control, home control, energy efficiency and other useful systems.
Here is a gas leak detector circuit that detects the leakage of LPG gasand alerts the user through audio-visual indications. The circuit operates off a 9V PP3 battery. An MQ-6 gas sensor is used in the gas sensor module. The sensor can also be used to detect combustible gases, especially methane.
A Fire detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection.A flame detector can often respond faster and more accurately than a smoke or heat detector due to the mechanisms it uses to detect the flame.
