Infrared thermometer solution based on Jiuqi microcontroller
Infrared thermometer is a temperature measurement instrument that uses infrared radiation. Before this, it was generally used to monitor product quality and electronic equipment. Such as the temperature conditions of mobile phones during operation. The infrared thermometer has the advantages of measuring temperature in seconds, high accuracy, and is simple and convenient to use. As an important medical instrument, infrared thermometers play a key role in epidemic prevention and control. Nowadays, due to the needs of epidemic prevention, it is widely used in human body temperature measurement, which greatly improves the work efficiency of epidemic prevention personnel.
It can conduct large-area monitoring in crowded public places, automatically track and alarm high-temperature areas, and cooperate with visible light video to quickly find and track people with high body temperatures. When the infrared thermal imaging body temperature rapid screening device integrates face recognition, mobile phone probe and other technologies, it can also grasp more information about people with high body temperature.
Xinling Technology also has an infrared thermometer solution based on the design and development of Jiuqi microcontroller. The following is a detailed knowledge description.
1. Principle of infrared thermometer solution:
Infrared thermometer consists of optical system, signal amplifier, photodetector, signal processing, display output and other components. The optical system concentrates the target infrared radiation energy in its field of view. The size of the field of view is determined by the optical components of the thermometer and their position. Infrared energy is concentrated on the photodetector and converted into a corresponding electrical signal. The signal passes through the amplifier and signal processing circuit, is corrected according to the instrument's internal treatment algorithm and the target emissivity, and is converted into a temperature value of the measured target.
2. Function introduction of infrared thermometer solution:
The infrared thermometer solution designed by Xinling technical engineers uses Jiuqi microcontroller NY8A054E as the main control chip. The package type is 8-pin sop. Through program burning, circuit design, and functional modules are built, the following functions can finally be achieved:
1. Button control: multiple button control, power on/off, temperature measurement, mode conversion;
2. LCD display: Backlit LCD display, reading in dark environment is still clear;
3. Unit conversion: Intelligent conversion of Celsius and Fahrenheit units;
4. One-click temperature measurement: One-click temperature measurement in seconds, simple, fast and highly accurate.
