Abstract:
This work details the development of a low-cost (<$15) wireless temperature sensor to measure the wide-range of temperatures found in extreme environments. The work is motivated by educational and outreach programs which utilize a simple timerbased circuit for a variety of monitoring applications. This circuit, commonly referred to as the Cricketsat, is often configured as a temperature to frequency converter for the purpose of atmospheric profiling. This work discusses the evolution and improvements of this design along with its utilization in a variety of applications.
Specifically, the contributions of this research are: 1. The development of low-cost, wireless sensor hardware able to measure extreme atmospheric temperatures from -90 °C to +60 °C. 2. The implementation of a linear-response design for improved resolution and simplification of calibration procedures. 3. Analysis of the linear sensor design and calibration procedures. These contributions are met while maintaining a simple circuit design beneficial for middle school, high school and college applications.
