PIR Detector F32 Fivestar

The electronic eye is an electronic component that is inserted into an electronic circuit such as: 1- LDR2 optical resistors- infrared photodiodes3- infrared photo transistors4- electronic eyes that are in the form of an IC (circuit). Complex) Manufactured 5. PIR Sensors There are, of course, sensors that are also called the electronic eye, but they do not actually function as a sight, but as an ear as they hear. These sensors are called ultrasonic sensors. A car of this kind. What is a Motion Sensor? Motion Sensor is one of the sensors I have used. Everyday smart homes are used as burglar alarms, which are marketed under different names such as eye and motion sensors, radars, PIRs, etc., due to the wide viewing angle and the process that these motion sensors perform from the environment. They are a major component 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 then use the information we receive from these sensors for future action. Different sensors are impossible. Here are some of the most common types of smart home sensors used: 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 that enables any action to be performed with an electrical signal, so anyone moving around the sensor angle 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, corridors or elevators, etc. Each person operates by opening the door at or before the entrance of the eye sensor and illuminates the entire corridor to exit the corridor. How the PIR Sensor Works in the Eye The primary sensor of a PIR eye sensor is a highly sensitive piece of light. Infrared is completely enclosed in a capsule and placed inside the eyes. Any infrared light that hits the surface of the eye sensor will cause changes 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 stimulate the The infrared sensor will only respond to temperatures of the human body or warm-blooded animals in the range of 0.5 mm and other wavelengths of infrared energy related to lights, sunlight, heating 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 zero, that is, below zero degrees, it emits light energy itself, the amount of energy emitted by the body depends on: 1) the amount of light reflected from the body 2) the temperature of the body itself 3) Physical 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. Invisibility is the spectrum of electromagnetic waves. In a typical office space, all the 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 are emitted at approximately the same wavelength. There is no one in the room or no one moves in 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. It stimulates the eye sensor for places. PIR2 sensor eye settings - PIR sensor night and day detection capability: Adjust the light. If set to sun, the device can operate day and night and when set to moon, it will operate only in light less than 2 lux. - Sensor Detection Spacing: Adjusts Sensitivity Places Eye Sensor You can adjust the distance you need according to the position of the Eye Position Sensor and its angle. Note: The sensitivity of the Places Eye Sensor is directly related to the direction of movement. 1 - Time delay: Time delay due to the requirement of the installer. Set up. The shortest adjustable time can be around 2 seconds and the maximum time is 2 minutes. What is the cause of the eye blinking? Because the PIR sensor is able to detect any object at a set temperature, you can manipulate the sensitivity of the eye by manipulating the circuit. Set to different objects and temperatures, but the reflection of sunlight on mirrors and other objects can cause an error in the eye location sensor, which can be resolved by installing the eye at the right angle at the right angle, but it can be said if: Percentage of error in places due to reflection of light; percentage of cause of error in places, due to fragments or rare wiring Set of devices and eyes are installed
