This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like a common breathalyzer. It has a high sensitivity and fast response time. The sensor provides an analogue resistive output based on alcohol concentration. The drive circuit is very simple; it only needs one resistor. A simple interface could be a 0-3.3V ADC.
This sensor has a high sensitivity and fast response time. The sensor's output is an analogue resistance. The drive circuit is very simple: power the heater coil with 5V, add a load resistor, and connect the output to an ADC.
