Overview

MQ316 Odor Sensor

Product Details

product details

The gas sensing material used in the MQ316 oral odor sensor is a semiconductor material with low conductivity in clean air. When there is a gas to be measured in the environment where the sensor is located, the conductivity of the sensor increases with the increase of the concentration of the gas to be measured. The change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit

Sensor characteristics

This product has high sensitivity to ethanol, hydrogen sulfide, and methyl mercaptan within a wide concentration range, and has advantages such as long lifespan, low cost, and simple driving circuit.

Main applications

Widely applicable to exhaled breath odor detectors, portable alcohol detectors, etc.
