Development of forehead temperature gun chip solution
A forehead temperature gun/handheld thermometer, also known as an infrared thermometer, can quickly and accurately measure the temperature of the human body. To use, simply align the probe with your forehead and press the button. The design of the forehead temperature gun provided by our company adopts an infrared sensor to collect the infrared radiation of the object and convert it into a weak mV-uV voltage signal. After voltage amplification, it is controlled by MCU, and then processed by our high-precision AD sensor. The digital signal is analyzed and processed by our MCU, and then the actual problem is identified and output to the LCD/LED screen display..
