A Study On A Localizable Cmos Temperature Sensor Based On Wireless Transmission

A CMOS temperature sensor is proposed, which is used in the wireless sensor and transmission network based on RFID technology. The current target's information can be tested timely and efficiently by using the intelligent electronic equipment in the Wireless Sensor Network. Meanwhile, the waste of human resources will be reduced. In this paper, the principle and hardware structure of the system are described. The results show that the CMOS temperature sensor's performance is good by being used in the RFID wireless sensor network. The accuracy of temperature is under 0.015 degrees C in the range between -40 and 125 degrees C. The error of the location system is within 0.4 meter in 5 x 5 meters range. Real-time transmission and data display can be achieved by using this sensor.
