The display of ordinary voltmeter is not clear enough, the measurement range is narrow and the anti-interference ability is weak. This paper studies the design and Simulation of voltage measurement system based on ADC0809. Combined with the actual production situation, using the function that ADC0809 has 8 analog inputs and can convert the analog input into digital display, this paper designs the circuit with single chip microcomputer chip AT89S51. Combined with the working principle of a / D converter and DC digital voltmeter composed of them, the voltage measurement of 0-10V is realized in this paper. The experimental results show that the measurement system has the advantages of accurate reading, wide measurement range and micro power consumption.

Humidity Monitoring

Exploring a kind of the humidity data acquisition system with higher performance-price ratio is vital to the environmental monitoring. At the present work, a novel of the humidity data acquisition system has been developed so as to collect and store the environmental humidity data. It consists of humidity sensor of DHT11£¬LED digital display and single chip microcomputer (SCM) of AT89S52. AT89S52 was used as the control chip which assembled with humidity sensor of DHT11 and digital display. Moreover, the behavior of humidity data acquisition was simulated with the software of Proteus; the results show that this designed system can collect the humidity data at bigger range. Therefore, the designed humidity acquisition system effectively achieves humidity monitoring, and has advantages of smaller volume, higher performance-price ratio, and portable.

Accurate measurement of the drilling mud resistivity is very important to analysis of drilling parameters. Therefore, it is necessary to produce an accurate measurement system. The resistivity measurement system which is introduced in this paper adopts STM8s single chip microcomputer as the control center. It sends control commands via I2C technology and completes the measurement of resistivity using AD5933. Then data is sent to the MCU. When the MCU deals with the data, LCD screen displays measurement results. The system has so many advantages: low power, portable, real-time measurement etc. It provides a reliable basis for analyzing the parameters of drilling.

It is necessary to realize the 1/2 blanking when designing the 4-1/2 digital voltmeter based on ICL7135 chip. The traditional digital voltmeter meters achieve the function by using the single-chip microcomputer program control. A new design should be considered when circuits are designed without the single-chip microcomputer. This paper combines the blanking terminal of the CD4511 decoding chip with the output signal of the A/D chip to design a complex logic gate circuit for realizing the blanking function. Experiment has been done to verify that the design of the complex logic gate circuit is feasible and it can guarantee the realization of the 1/2 blanking.

This paper concentrates on the sustainable use of energy, water, and raw materials to increase production to meet the demand of a high population with available areas. In this work, a kind of automatically controlled greenhouse system of single-chip microcomputer based on sensors is described. This paper presents the system's hardware structure, working principle and process, and a large number of experiments on the effect of the control system. Five control parameters are chosen to increase the yield of the greenhouse, which can be used in indoor breeding and planting. Control actions are performed on the basis of the fusion of different parameters. For the actuation system, the greenhouse is controlled by relays. The proposed control framework permits sparing costs related to wear minimization and delaying the actuator's life, yet continuing promising execution comes out. Results and conclusions are derived by methods of simulation results.
