Characteristics for selection for sensor for movement for turning on for light on stolbit
Title: Sensory for movement 
Stalbishcheto is an element in the housing fence, some of which carefully pay attention to clarification. In the project, the scheme for clarification and the time for construction is taken foreseen:
- It is necessary to provide illumination in conditions of insufficient external light. Stalbishcheto is a source on a naranyavan with a lipsa for clarification on a steppalat.
- A short time for advancing on the pillar of the day. Pict on movement in the housing to protect the attack at one hour of sutri and evening. In kashchit stalbite, you will crawl even more in a row. For the night and the day of the day, Svetlinat all wasted uncontrollably, increase the amount of energy.
- Impossibility for candidacy transitional switches on the public space and inexpediency on the installation in the brownie from a small child. In these cases, the cases of svetlinata continue and burn, without and without exception of the day.
Containment: 1. Principle for action 2. Species sensory for the sheds 3. Items per device 4. Where do you install the sensors? 5. Manage per device
Solve the problem with turning on the light at the exact time of the sensor for movement, for yes turn on the light on the column.
When you choose a device, take a look:
- Temperature on the ground for installation.
- Ъgl on a curve in the vertical and horizontal plains, guaranteeing that in order to use it, someone will appear from two pages on the column.
- Goleminata for the current on the switch, enough for the switch on the lamp, applici, turn on the lamp.
- The situation in this case, the presence of a light source on the outside, a heating device, debelinate and material on the wall and block - these parameters are important when choosing a type of detector.
Principle for action
Once a person has appeared in the zonata on the curve, the relay (mechanically or electronically) has been inserted into the electronic circuit, now the creation. Work contacts on the relay, zatvaryan, zakhranvane on the lighting rod.
When looking at the outside, the view of Horata is taken foreseeing the technical characteristics:
- Body temperature, different from external background.
- Move ahead of space with a determined speed.
The dispute of the principle on the curve of the characteristics of the sensory se distinguishes:
- Radio vollni;
- ultrasounds;
- acoustic;
- infracherven;
- combine
Varieties of sensors per movement
radio
The principle on the action on the sensorite for the curve on the radio wave, based on the Doppler effect, was studied at the school in a course in physics. High-frequency radio waves are in the vicinity. The signal is reflecting from the object and the north of the receiver. Akoima moving objects in the zonata behind the curve, the frequency on the rotation of the signaling change. The trace of the cato and catch the difference between the emission and receipt of the signal, the electronic circuit sends the signal to the relay, some including the light.
Devices for action on radio waves and deficiencies, which limit the use of:
- Pull up the walls, don’t forget about the radio waves - perhaps even turn on the light from the movement for a person who is standing behind an obstacle.
- Designed with a radiator for radio waves that negatively affect the life of organisms.
Sensors are used actively for outdoor operation, such as meteorological conditions do not affect the sensitivity of the device.
Designed to work on the sensor on the open
Ultrasound
The operation of the device is based on the principle of catoradio waves, but covers the radiation within the boundaries of ultrasound.
Acoustic
The principle of action is reflected in the title. The device emits sound and vibration and reacts by turning it on to lightening. Lack of embarrassment in the device of false alarms.
Infrared Sensory
The temperature in the Czech Republic was 36 ºC. Round the objects to heat up under (walls) or over (glasses of insight) normal body temperature.
Infrared sensor equipment from bream to Fresnel, sometimes dividing the room into sectors.
Infrared light in the sensor
Scheme for working on infrascan sensor
Signal for the temperature on the surface of the pyrodetector. It generates a general signal for a low temperature in the sector and sends it to the electronic circuit. Signal se memorizing and recognizing cato standard. Chowek, licking into a zonata on a curve, changing the temperature in one or more sectors. The signal is shared by the change, the difference from the referent. The sensor generates a command to turn on lightening. For yes, turn off false alarms, the program and the possibility of changing smoothly the reference temperature. Goods are necessary in the case of a gradually flooded space, for example, in summer den.
Preferences for the device:
- No radiation in space. Vv verigata on the device that the traitor is active, therefore, there is a small chance for a scupvan.
- Breams on Fresnel are in a state and a sjzdade zone for a curve with any form. Up to 180º horizontal or vertical. When tavanning the zonate model on a 360º curve.
- Mounted on an additional lens, some of the space is curved under the device, then behind the eye, except for the curved on golems and pets.
Border on the zonate beyond the curve under the format on the diagram
There is a significant lack of reaction to the movement of the air during. The problems of all the eliminir are due to the correct installation on the device - the zonate on the curve is saturated with the opposite side on the ventilation open and heat the ward.
Combined
In a combined scheme for a device, it foresees two principles to work at the same time. Svetlinata is a fuse, once a person was spotted in two beginnings, from exclusion to false inclusion to clarification.
Differences in price on the sensorite, which are distinguished according to the principle of work, are small and the conditions for work are taken into account when choosing.
Typical sensors for the sheds
In addition to the principle of work, when you choose a sensor for light, you will take foresight:
- Format on a zonate on a curve (girth, tight or wide for visibility).
- Myasto for installation (wall, tavan).
- Please protect the device from the battery, constant voltage +12 V, protect from the 220 V voltage.
- The power is on the natovarvane, it is capable of costing a working relay. For LED polypoles and lamps, devices up to 60 W are used.
- Ranges for setting the duration for operation until the moment of shutdown.
- The presence of something on the photocell. When enough light is around, the sensor is nim and reaction.
Sensory, gradate in the illumination of the body, do not scatter in the store. The device is connected to a 220 V network, without the need for an additional electrical connection, forestry and install it yourself.
Items per device
Design per device including:
- Kadar.Designed for protection of parts from the device from damage, dust and mrskotiya. Model for installation at the top of the horizontal surface allows installation in the top of the tavani.
- Electronic circuit. Opened the presence of this on a person and carried out the protection of the lampat’s lamp.
- Mounting bracket. The design of the element trimming the device is vertical and horizontal plain.
Where do you install the sensors?
The area was chosen for the installation, which is all foreseen in the ground, it was covered on the vase of the area on the approach to the person to the stone.
Due to the complexity of the view of the column, sometimes the configuration does not allow the inclusion of light at the end and the burn from a single sensor, the installation of two devices from a parallel connection.
Nai-chesto sensor se montira in the long sector on the pillarbit.
Sensorite not se montirat:
- Ultrasound and sound devices in the zone with the temple are acoustic noise.
- Radio waves close to fluorescent lamps with starters including chains. The movement is on the screen from the current of the sensor operation.
- Infrared is not the purpose of heating on radiators, open the gates, see through, open the ventilation. Do not saturate the device with a bright sun light.
Manage per device
It is turned on and adjusted all by means of controls, placement on the bodies, including adjustment to low light, at some sensory soil and including lightness, at which time choras will appear.
By adjusting the sensitivity, you can choose the size of the zonate for the curve as needed.
The change in the duration on switching on is due to the setting for the interval from time to work on the lighting body.
Some models allow you to forcibly turn on the device by exercising the function on the switch.
They will explain the choice and call on the rules for installation, help them to avoid injury when they fall from the step into the dark, draw a mark for energy - turn on the light itself at exactly the same time.
