Remote Alarm Monitor System Based On GSM and ARM

This paper presents a remote monitor and control alarm system based on GSM and ARM. This system uses ARM-based microcontroller LPC2368 as the MCU, a smoke sensor MQ-2 to detect the harmful gas, the temperature sensor DS18B20 to monitor the temperature, the humidity sensor HS1101 to check the humidity in the room. Also we use gate magnetic switch, we fix them on the door and windows to monitor the invasion. If the householder comes back, he can enter the password through the keyboard. The microcontroller then disables the alarm from the gate magnetic switch. Once the abnormal occurs, the MCU gets the alarm signal immediately, and the system controls the camera to take photos, and send multimedia messages (MMS) to inform the alarm information.

Research on Temperature Property of Piezoelectric Vibration Accelerometer Based on Cymbal Transducer

The new type of piezoelectric vibration accelerometer was studied, which sensitive element is cymbal piezocomposite transducer with 2-(0)-2 connectivity rather than conventional piezoelectric ceramic. The temperature property of output voltage of this new piezoelectric vibration accelerometer was investigated. Put the temperature sensor DS18B20 into the vibration accelerometer to detect the inner temperature properties of the vibration accelerometer. Using microcomputer to record the static output voltage values and gained the relationship between the temperature and static output voltage. Designed the artificial neural network module and compensated the output voltage error produced by temperature drift. The result showed that the relative error of static output voltage was decreased from 26.73% to 3.66% in the temperature range of −20°C to 60°C. The compensation method based on the artificial neural network can be used for compensating the temperature properties of output voltage sensitivity of vibration accelerometer.

Temperature Detecting System of Beer Fermentation Based on DS18B20

This Paper introduces a temperature detection system in beer fermentation. A temperature monitoring system with characteristics of bus topology structure is composed of industrial computer, temperature detector, bus converter, transmission bus and especially 1-wire digital temperature sensor DS18B20. Four-core cable is used to form a tree-like or star-like network, in which 54 digital temperature sensors existing on 18 fermentation tanks can be connected. The quantity of junction wires between temperature sensor and computer will be reduced greatly. Temperature detector provides power supply for bus converter and DS18B20 through Four-core cable. Because bus converter has used hardware fault detecting technology, the fault temperature sensor can automatically detach from the main bus and will not affect normal working of other sensor in network. So to solve the problem of a certain sensor or branch's damage causing the paralysis of entire bus. The length of detecting temperature bus can reach more than 500 meters. These all make system maintenance and expansion easy. The experiments show that this system is characterized by high intelligence, high-precision, capability of making temperature test on multi-points and compensating function. The method has a good applicable value to the temperature test.
