Fermion: MEMS EtOH Sensor (breakout) Wiki - DFRobot

Introduction

Fermion: MEMS EtOH sensor employs state-of-the-art microelectromechanical system (MEMS) technology, endowing the sensor with compact dimensions (13x13x2.5mm), low power consumption (<20mA), minimal heat generation, short preheating time, and swift response recovery. The sensor can qualitatively measure ethanol concentration and is suitable for ethanol gas leakage and portable ethanol detector. The MEMS series currently encompasses 11 different types of gas sensors (HCHO, CO, CH4, VOC, NH3, H2S, EtOH, Smoke, Odor, H2, NO2), which can be combined as per specific requirements. Please note: This sensor is capable of qualitative measurements only. For quantitative measurements, kindly consider purchasing the Factory-calibrated Gas Sensor.

Sample Code

1.Read the sensor raw value

int sensorPin = A0;
int sensorValue = 0;

void setup()
{
  Serial.begin(9600); //Set serial baud rate to 9600 bps
}

void loop()
{
  sensorValue = analogRead(sensorPin);
  Serial.println(sensorValue);
  delay(100);
}

Expected Results

Open the serial port monitor and get the original value of the sensor.
