ENGINEERING WORLD HEALTH TEMPERATURE TESTER Team: Carly Brown, Sarah Offutt, Ryan Thome, Sasha Cai Lesher-Perez BME 201 May 5, 2006

Abstract Our project, from Engineering World Health, was to design a device for testing the temperature in an incubator or water bath. The temperature tester must signify a deviation of temperature of 0.05 ° C from 37 ° C. The greatest restriction placed on our design was the cost of the device, $3.00 per unit. The final design is based on a circuit that used a Wheatstone bridge with a thermistor, a potentiometer and a dual comparator that is connected to two LEDs to alert the user of temperature deviations. The circuit is incased in PVC piping and epoxy, and features a removable battery. Future work on the project includes increasing battery life and decreasing size.

Problem Statement We will design a temperature tester that indicates changes in a water bath or incubator temperature by more than half a degree from a specified temperature of 37 ° C
