Infrared light sources are widely used in gas analysis, laser ranging, robot positioning, remote sensing, non-contact temperature measurement and many other fields. However, due to the relatively high power of infrared light sources, the development of related infrared light source application technologies is restricted. With the rapid development of integrated circuit technology in recent years, the performance of electronic components such as microcontrollers and high-power field effect transistors has been greatly improved, making the use of microcontrollers to control infrared light sources a mainstream trend. This design uses the MSP430 MCU and the stabilized voltage to realize the voltage control of the infrared light source and the microcontroller technology to control the on and off of the ...
