MQ8 Hydrogen Gas Sensor Circuit Built with an Arduino. In this project, we will go over how to build a hydrogen gas sensor circuit with an arduino. The hydrogen gas sensor we will use is the MQ8 sensor. This is a sensor that is sensitive to effects of hydrogen gas. Hydrogen gas (H 2), at room temperature and under standard pressure conditions, is tasteless, odorless, and colorless. Hydrogen ...

20210201· Let''s discuss the project plan and how to connect the MQ135 Gas Sensor with Arduino. The story is simple. We are going to connect the MQ135 gas sensor with Arduino to detect Gas. If the sensor picks unusual gas in the environment, we will start a buzzer as an alarm. We can also send SMS using the GSM module. But, in this project, we will only play a buzzer. We will also include one red …

MQ3 Alcohol Sensor. The MQ3 module has 4 pins including both digital and analog outputs, VCC and Gnd. MQ3 alcohol sensor module can be easily interfaced with microcontrollers and development boards like Arduino Boards, Raspberry Pi etc. MQ3 Alcohol Sensor Pinout. The readings from the MQ3 sensor will be displayed via the Arduino mega on an ...

20201117· MQ135 Gas Sensor is an air quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke, and CO2. MQ135 sensor can either purchased as a module or just as a sensor alone. In this project, we are using an MQ135 sensor module to measure CO2 concentration in PPM. The circuit diagram for the MQ135 board is given below:

20200705· The MQ135 gas sensor module has four pins (standard male headers) as shown above. The air quality information is readable via the AO pin. Since AO is a varying voltage, this pin should be connected to one analog input of a DO pin is an opencollector digital output (but with a pullup resistor onboard) that becomes low when the detection level exceeds a predefined level.
