“…As shown in Figure 1, the STC89C52 3,4 single chip microcomputer is used as the main control MCU. The digital quantity corresponding to different voltage values is output through preset DA, and the digital quantity is input to the DA conversion chip through the IO port of the single chip microcomputer.…”

This paper designs and implements a low frequency signal generator based on the interrupt and timing functions of the single chip computer. The system uses STC89C52 single chip microcomputer as the controller, outputs different types of signals through AD signal conversion, and outputs after the LM358 amplifier amplifies and potentiometer adjusts the amplitude. According to different needs, the system outputs different waveforms, frequencies, amplitudes, and phases through corresponding keys, and uses LCD to assist in displaying the generated signal information. The lower computer software of the system is implemented on Keil five software using C language, the simulation circuit is implemented on Proteus seven software, and the drawing of circuit schematic diagram and PCB circuit diagram is implemented on Altium Designer 18 software.

This article discusses the manufacture of formaldehyde content test kit device. The device made can find out whether formalin or samples that are dropped are reagents, its characteristics can be processed electronically to determine the levels of formalin detected in the reagent/test kit. The design is made using AT89S51 microcontroller. Detection of formaldehyde levels using a color measurement method for reagent fluids consisting of R, G, and B values. Measurement of these color parameters using the TCS230 sensor. With this device, it is expected to facilitate health workers, especially health analysts, to automatically test the level of formaldehyde in food with a display on the LCD. The result of device test, this device is feasible to use by the percent error value of less than 10%.
