This system consists of a pressure silicon sensor, calibration module and wireless module. The pressure sensor used in this work is a piezoresistive silicon sensor that developed by Technical University Berlin. After calibration of the sensors output signals, the XBee-chip was used for wireless transmission. The three components with peripheral circuits and batteries were integrated in a 50mm × 50mm PCB. The system was then tested in a climate chamber at different temperatures and pressures. Programs for signal receiving and processing were developed in Matlab-environment. The experimental results show that this system works well for the short range (15m indoor).

This paper reports a readout system for a piezoresistive accelerometer which is fabricated by LTCC thick-film process technology. The authors first introduce a LTCC compatible design of this new kind of accelerometer, which is based on piezoresistive phenomenon. As the performance of the accelerometer circuitry is affected by temperature, a readout system is introduced for compensating the temperature drift and the non-linearity of this piezoresistive accelerometer by using the MAX1452 processor. The authors give the principles of the temperature compensation and the executive processes. The readout system also includes a ZigBee wireless transmission system and a real-time curve display window. Some tests on the system are carried out and the results manifest that the readout system designed in this paper is workable.

In the technology of temperature measurement, the sensor is an important part of system. But with the increase of the number of sensors, it will undoubtedly bring with a lot of data cable. Compared with wired communication technology, wireless communications technology has the advantages of low cost, simple structures, low impact of environment. So the wireless communication technology meeting with the requirements of data communications has become a more practical, fast and efficient way. This paper describes a multi-channel temperature monitoring system using nRF905 wireless transmission module, STC89C52RC MCU and DS18B20 temperature sensor as core. Functions such as sampling, analysis, display, alarm and others can be done automatically by the system, dates transmitted by wireless module, and the system can realize the function of real-time monitoring of temperature.

This device uses GPS module to sample the data, and transmits data with the wireless module. The handheld terminals can display information such as longitude, latitude, time independently. The transmitting section collects data which is parsed and processed by the MCU, and displays it on the Liquid Crystal Display (LCD). The receiver receives and analyses wireless data, then displays the data including the current geographic information through the upper machine at the same time. Experiments show that the device could realize the function of positioning and transferring information within 200 meters and we could also use Google Map, the PC software, to get map information. This device, compared with the traditional system, is small in size, light in weight, easy carrying and can accurately position an object. It can be widely used in the sphere of investigation, exploration, navigation and positioning.

Abstract Along with the historical process of the industrial revolution, the automobile has undoubtedly made life more convenient. But at the same time, various problems also come along: Traffic jams are becoming more and more serious, and problems such as parking are becoming urgent problems. This design uses STC89C52 microcontroller, through the infrared sensor module to detect the information of the garage, then the nRF24L01 wireless module is used to carry out the wireless transmission of master and slave information. Finally, the LCD1602 LCD screen is used to establish the human-computer interaction page, and an intelligent parking space management system is designed. The owners can easily check the parking lot to understand the flow of the parking lot through the system, and judge whether to enter the parking lot, saving time. At the same time, it is easier to integrate with other intelligent systems, which provides a foundation for more advanced management and is the premise for making the parking lot a highly intelligent product in the future.
