A1301 Hall Effect Sensor – Linear

This semiconductor gas sensor detects the presence of alcohol gas at concentrations from 0.04 mg/L to 4 mg/L, a range suitable for making a breathalyser. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.

This semiconductor gas sensor detects the presence of Carbon Monoxide at concentrations from 10 to 1,000 ppm and combustible gas from 100 to 10,000 ppm. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
