This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer.
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.
