Design and Application oF Multi-Spots Temperature Acquisition System Based on RF

In order to study the temperature change rule of car parts and in-car air which under the sunlight condition,the wireless multi-spots temperature acquisition system is designed.The system has taken the STC89C52 single chip as the core,The DS18B20 integrated temperature sensor is to acquire the temperature of the car parts,and the nRF905 wireless transceiver module is for the wireless data transmission,using VB language to write PC monitoring program and the temperature data which sent to the monitoring software to display will be saved automated.The temperature acquisition system can acquire the temperature of multi-spots,wireless data transmission,display and auto-save,and provide the actual data for the study of the change rule of in-car temperature.
