Description
The sensor detects the concentration of benzene, alcohol and smoke in the air, the result can be obtained measuring the voltage on the analog output. The system is supplied with the voltage from 2.5 V to 5 V. It has a digital and analog output, making it compatible with most of the commissioning modules including Raspberry Pi and Arduino.
Specification

The product is compatible with Arduino In the web, you can find sample programs for Arduino and STM32. |
The module has the connecting cable with female ends.
The digital output D0
With the help of the potentiometer placed on the reverse side of the board, set is the threshold above which the output D0 is changed from a high to a low status. The output D0 can be linked directly with a microcontroller or commissioning set, including Arduino, or for example, with a module of a buzzer which will signal too low or high level of gases in the air.
Analog output A0
The sensor has an analog output A0 which must be connected to the pin of the converter A/D (of analog input in Arduino). This will allow you to measure the proportional voltage signal and more accurately determine the concentration.
