Tindie Blog | A CO2 Sensor for ESPHome

2020-08-13· A CO2 Sensor for ESPHome. With so many people spending so much time indoors lately, Greg from Greg’s Tinker Town wanted to develop a board that could interface an ESP32 to an MH-Z19B CO2 sensor – and so that’s exactly what he did! The MH-Z19B is a pretty neat sensor. It uses non-dispersive infrared to detect the concentration of CO2 in ...

Gravity: Analog CO2 Gas Sensor For Arduino (MG-811 Sensor ...

This is the first CO2 sensor in the Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (the voltage is lower than the threshold), a digital signal (ON/OFF) will be released. It has ...

Guide for MQ-2 Gas Sensor with Arduino | Random Nerd Tutorials

2016-05-05· The MQ-2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, the lower the output voltage. When the Arduino reads analog values, it returns 1023 when it reads 5V, and ...

CO2 Monitoring As an Anti-Covid19 Measure -

The "heart" of the device we propose here is an infrared CO2 sensor piloted by an Arduino-compatible microcontroller, to which are added a visual interface and a logging device enabling the continuous recording of CO2 levels on micro-SD cards. The device continuously measures, records and displays the date, time and the CO2 concentration in ppm. An RGB LED next to the screen indicates three ...

Measuring CO2 Concentration using Arduino and MQ-135 Sensor

This project looks into designing and testing a CO2 sensor using an Arduino UNO. An MQ-135 sensor is tested under different conditions in order to obtain detection limits and measure trends. The literature shows that there is around 400 PPM of carbon dioxide in the atmosphere, the average indoor values range from 35-450 PPM and the maximum acceptable level is around 1000 PPM. The MQ-135 ...
