    This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is 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 analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

    Features:

    • 5V DC or AC circuit
    • Requires heater voltage
    • Operation Temperature: -10 to 70 degrees C
    • Heater consumption: less than 750mW* 16.8mm diameter
    • 9.3 mm height without the pins
