Development of an Electronic Thermometer
The popular ethanol-in-glass thermometer exhibits numerous inadequacies. These inadequacies include not being able to measure very cold temperatures, potential exposure to hazardous material content, and having a low thermal co-efficient. I investigated a safer and more accurate solution through the design, development, and testing of an electronic thermometer using an Arduino, TL072CN operational amplifiers, and a LM34 transducer. A circuit conditioned a signal at the voltage output of a LM34 transducer into an analog signal which was displayed digitally through an Arduino and multimeter. Overall results included the LM34 transducer to have a decreased percent error as a temperature was increased.
