Randomized trial demonstrates real-time thermistor resistance monitoring in various sensors, suggesting improved testing efficiency.
ABSTRACTA low-costmicrocontroller-basedsystem is developed for measurement of sensor ohmicresistance. The instrument can measure resistance from few ohms up to 1 M-Ohms usingselectable range to accommodate for verity of sensors and wide variation of sensor resistancewith temperature.To get a real-time correlation between the sensor resistance at differenttemperature, a temperature measurement circuit based on LM35 is also included.The systemhelps to reduce testing time. The data is stored in the memory of the computer in excel formatand it is available for future use. The automated system has also eliminated manual interferenceand its limitation and disadvantages during tests.
