The level of comfort in a room and the safety of people depend on well-selected and correctly installed fixtures. One of the elements that simplify movement in the dark is a night light with a motion sensor
The principle of nightlight with DD
All night lamps with motion sensors work on the principle of changing the parameters of the emitted signal when a person or other living creature falls into the zone of its action.
Circuit closure occurs under the influence of such factors:
- temperature change;
- beam interruption;
- changing the characteristics of the signal.
In all cases, a relay is triggered, which supplies electricity to the lamp. The continuation of its glow depends on the factory or independently made settings. In most cases, the lamp goes out after 5-10 seconds after a person leaves the signal range.
Lamp classification
On sale is a wide range of devices that differ in signal type, power, location and type of installation. Thanks to this diversity, it will not be difficult to choose a device that meets the requirements.
By the type of emitted waves, devices are divided into the following categories:
- Infrared Turning on occurs when the temperature decreases and rises in the room. Changes are recorded by IR sensor.
- Microwave The operation occurs when the sensor responds to a change in the frequency of waves in the territory that falls into its sector of operation.
- Ultrasonic They work on the principle of echolocation, which is used in the manufacture of radar and sonars.
- Combined. They consist of two or more sensors, which increases the reliability of devices, but increases their energy consumption.
Devices can work from a household network 220 V, batteries or solar panels. Products are installed in residential and utility rooms, along garden paths, on the walls of street buildings.
By the method of fastening, the devices are divided into stationary and removable. The first option is rigidly attached to the base and is designed to be constantly in one place. Lamps of the second type are mounted on the surface with Velcro, hooks, brackets or stuck into a charger that performs the function of the base. According to the device, the lamps are overhead and recessed.
