MH-Z14A is an Infrared Carbon Dioxide Sensor for accurate NDIR (nondispersive infrared) Co2 measurement using Arduino, STM32, Raspberry Pi. This NDIR Co2 sensor is a small size, common type sensor, NDIR principle to sense the presence of CO2 gas in the air. This NDIR Co2 sensor provides good selectivity, long life and non-oxygen dependent.
By knowing the exact concentration of CO2, we can do something to reduce the atmosphere's CO2 level and to protect our earth. For that reason, DFRobot eningeer's designed a high quality CO2 sensor. This is the first CO2 sensor on the opensource hardware market. The output voltage of the module falls as the concentration of the CO2 increases.

I tried a number of analog CO2 sensors for that project, but I ran into calibration issues - until I got a K30 CO2 module. This is a NDIR, digital, auto-calibrating sensor, so it's pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino.
Jan 17, 2018· Breathe easy with the SGP30 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing and fully calibrated output signals with a typical accuracy of 15% within measured values. The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals.
Feb 02, 2020· MG811 mySensor = MG811 (A0) // Analog pin A0. For the sensor's calibration follow the steps describe below: Power on the sensor. First step. Put the sensor outdoor or indoor with good ventilation. Wait at least two (02) hours - for warming up. Read it's measurement - You get 400ppm reference voltage. Second step.
There are different gas sensor modules on the market. Dependent on model it can be used to detect different gases. See buying guide for details.. EasyIoT sever. Add Virtual node in EasyIoT server there is no support for gas sensor so we will select Digital input (DI) type of sensor.
About this project. Project aims to control lights and CO2 admission to a planted aquarium. User has 2 lights time interval to set and one CO2 time interval. In the defined time intervals relays that control lights and CO2 are turned on or off. Additional sensors were added to read data about the aquarium …
May 06, 2021· Measure CO2 with MQ-135 and Arduino Uno - Rob's blog. Using a very cheap MQ-135 gas sensor bought from with an Arduino nano or any other arduino variant to measure CO2. I have been banging my head against the wall for days now and I have not found anything that can solve my issue on the internet either.
