Wireless temperature sensor network for refrigerated vehicles

Convenient and reliable temperature monitoring systems are increasingly demanded in vehicle refrigerators. However, difficulties exist in wiring between temperature recorders and sensors on vehicles for example trailer-tractors. To solve this problem, this paper investigates possible technologies for wireless sensor networks. The investigation covers temperature sensor technologies, mathematical models for temperature conversion and wireless communication technologies for sensor networks. This paper also presents a prototype of a wireless temperature sensor network. The conclusions are drawn out based on the investigation and implementation.
