Abstract
A semiconductor die includes a chemical sensor, a digital to analog converter, and microcontroller formed therein. The chemical sensor detects the presence of a chemical and outputs an analog signal to the digital to analog converter. The analog to digital converter converts the analog signal to a digital signal. The analog to digital converter outputs the digital signal to the microcontroller. Microcontroller calculates a value of the concentration of the selected chemical.
