PIR Detector F33 Fivestar

The electronic eye is an electronic piece that is inserted into its own electronic circuit, such as:

1- LDR optical resistors

2. Infrared photodiodes

3 - Infrared transistor photo transistor

4- Electronic eyes that are made in IC (integrated circuit)

5. PIR Sensors

Of course there are sensors that are also called electronic eyes, but in fact they do not function by sight but by hearing. These sensors are called the Ultrasonic Sensor.

What is a Motion Sensor?
Motion Sensor Motion Sensor Sensors are one of the sensors used today in the smart home as burglar alarms which are marketed under different names such as optical and motion sensors, radar, PIR, etc. due to the wide viewing angle and processor These motion sensors make the environment one of the key components of smart home theft systems, and most companies use these motion sensors in their theft reporting projects. We are now examining the performance of such sensors. In order to have a smart home, we need different types of sensors to get a better understanding of the status of the house or location, and to use the information we receive from these sensors for future action. Different sensors are impossible. Here are some of the most commonly used sensors in the smart home.

What is PIR?
PIR stands for Passive Infrared Sensor. The passive term in this sensor means that it does not emit any energy and only receives infrared radiation, and the term infrared or infrared radiation in physics is partially referred to as the spectrum of electromagnetic radiation. Starting from the wavelength range of visible red light to microwave invisible microwave waves, if you open the alarm in the eye, you will find a circuit with a PIR sensor in the middle. Sometimes they mistakenly use this eye with motion sensors. The PIR sensor is a sensor that receives the heat traces of the human body and converts it into a digital or analog electrical signal, allowing anyone to move with an electrical signal, so anyone moving in the angle of view of the sensor with In finding the infrared radiation emitted from the body, the exciter sends a command to the central controller system. For example at the entrances of corridors or elevators, etc. Each person operates by opening the door at or at the entrance of the eye sensor and illuminates the entire corridor path so that the person exits the corridor.

How PIR Sensors Work in Places
The primary sensor for a PIR eye is a highly sensitive infrared light that is enclosed in a fully encapsulated capsule inside the eye. Any infrared light that hits the surface of the eye sensor will cause a change in the electrical properties of the eye sensor. This change is detected by an "electronic detector" circuit and then amplified, causing an alarm on the PIR output to trigger The infrared sensor will only respond to temperatures of the human body or warm-blooded animals in the range of 1–2 mm and other wavelengths of infrared energy related to lights, sunlight, warm equipment. Filter and so on to reduce noise to detect the presence of a person within their range will filter the If it is above absolute zero, that is, below zero degrees, it emits light energy itself, the amount of energy it emits from the body depends on:

The amount of light reflected from the body

2. The temperature of the body itself

The physical dimensions of the object

4. The amount of internal energy produced (activity and metabolism) and the wavelength of this light depend on the temperature of the body.

5. Difference of body surface temperature with ambient temperature

Much of the energy emitting from the body is of the infrared type, which is part of the invisible part of the electromagnetic spectrum. In a typical office space, all objects, walls, floors, lights, etc. emit infrared light, since the surface temperatures of the surrounding objects are close to the ambient temperature, both of which emit almost the same wavelength. When no one is in the room or when one is not moving, the pattern of energy distribution is constant and power is the pattern. Now if someone enters the room, this pattern will collapse in two ways. The body creates a barrier between reflection and the propagation of waves by the environment. The body absorbs its infrared energy, which increases the amount of energy in the room.

Places Eye Settings with PIR Sensor
Night and day detection capability by PIR sensor: Installer can adjust the light according to your needs. If set to the sun, the device can function day and night and when set to moon, it will only operate in less than 1 lux in light.

1. Sensor Detection Spacing: By adjusting the sensitivity of the eye area sensors, you can adjust the distance required depending on the position of the eye sensor and the angle of its location.

Note: The sensitivity of the eye sensors to places is directly related to the direction of movement.

1- Time delay: The time delay is adjustable according to the needs of the installer. The shortest adjustable time can be about 2 seconds and the maximum time is 5 minutes.

What is the reason for the blink of an eye?
Since the PIR sensor is capable of detecting any object at a given temperature, you can manipulate the circuit to determine the sensitivity of the eyes to different objects and temperatures, but the reflection of sunlight on the mirror and other objects can cause errors in The eye sensor is a place that will fix this problem by installing the eyes at the right angle at the right angle, but it can definitely be said that if 5% of the places' eyesight is due to light reflection; Device and eyes are installed
