Winsen Semiconductor Type Alcohol Sensor is an original and brand new mini size alcohol sensor for gift-type breathalyzer use.

The sensitive material of the MQ303B gas sensor is a semiconductor material which is with lower conductivity in clean air. When the target alcohol gas exists, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.

Semiconductor Type Alcohol Sensor has a high sensitivity to Alcohol gas. It is a kind of low-cost sensor for kinds of applications and also a mini size gift-type Alcohol sensor breathalyzer.

Applications :
It has a high sensitivity to alcohol and quick response and resume, widely used in portable alcohol gas detectors.


Features:

  1. Responsive to Alcohol gas
  2. Compatible with 5V
  3. Cost-efficient

Package Includes:

1 x MQ303A Semiconductor Type Alcohol Sensor
