Which four gases are detected by the four-in-one gas detector
An infrared thermometer is a temperature measuring instrument that uses infrared radiation. Before that, it was generally used to monitor product quality and electronic equipment. Such as the temperature during the operation of mobile phones. The infrared thermometer has the advantages of second temperature measurement, high precision, and simple and convenient use. As an important medical instrument, infrared thermometer has played a key role in the prevention and control of the epidemic. Nowadays, due to the needs of epidemic prevention, it is widely used in the temperature measurement of human body, which greatly improves the work efficiency of epidemic prevention personnel.
It can conduct large-scale 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 temperature. When the infrared thermal imaging body temperature rapid screening instrument integrates technologies such as face recognition and mobile phone probes, it can also grasp more information about people with higher body temperatures.
Xinling Technology also has an infrared thermometer solution based on the design and development of Jiuqi single-chip microcomputer. The following is the specific knowledge description.
1. The principle of the infrared thermometer scheme:
The infrared thermometer is composed of optical system, signal amplifier, photodetector, signal processing, display output and other components. The optical system concentrates the infrared radiant energy of the target in its field of view, the size of which is determined by the thermometer's optical components and their location. Infrared energy is concentrated on a photodetector and converted into a corresponding electrical signal. The signal passes through the amplifier and signal processing circuit, and is corrected according to the instrument's internal treatment algorithm and target emissivity, and converted into the temperature value of the measurement target.
Second, the infrared thermometer program function introduction:
In the infrared thermometer solution, the main control chip adopts NY8A054E, a nine-chip single-chip microcomputer, and the package type is 8-pin sop. Through program burning, circuit design, and building functional modules, the following functions can be realized in the end:
1. Button control: multiple button control, on/off, temperature measurement, mode conversion;
2. LCD display: backlit LCD display, reading is still clear in dark environments;
3. Unit conversion: intelligent conversion of Celsius and Fahrenheit units;
4. One-key temperature measurement: One-key temperature measurement in seconds, simple and fast, with high accuracy.
