Tobacco frost-proof wireless temperature data acquisition system based on ARM

With the ARM development system as a data acquisition and processing platform and Linux system as the operating system, using DS18B20 digital thermometer as a tobacco field temperature acquisition sensor, through the wireless digital transmission module and temperature data acquisition module matching S3C2440 chip, this paper describes how to collect and process in real time the field temperature data measured via the thermometer for a small area layout of the tobacco field, and upload it to the dedicated PC in the Front Protection Command Center, so as to show the tobacco field temperature data, temperature variation curve, frost point (threshold) alarm and so on. Featuring easy and quick access, low power consumption (suitable for field conditions) and high security, the system applies to temperature acquisition in a small area of field.
