[solved] Problem reading CO2 concentration from COZIR sensor

· I am trying to build an incubator that can control CO2 concentration at 5% by volume. Detailed instructions are available here: Project specification: MCU: Arduino Mega 2560 R3 CO2 sensor: COZIR SprintIR-WX-20 0-20% CO2 sensor (Data sheet attached in the attachment and HERE) I tried to test the sensor with the test code provided by the author: #include "" #include …

Tindie Blog | CO2 sensor

It uses non-dispersive infrared to detect the concentration of CO2 in the air. This makes it pretty immune to the percentage of oxygen in the air, and with no moving parts or chemical sensor elements it should have a fairly long lifespan. It can detect concentrations up to 5000 ppm, at which point most humans are unable to focus well, complain of “stuffy, stale air” and may also start to ...

Tindie Blog | A CO2 Sensor for ESPHome

· 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 ...

Arduino CO2 Sensor detector Carbon Dioxide module ...

This is the first CO2 sensor in 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 (voltage is lower than threshold), a digital signal (ON/OFF) will be released.

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.

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

· The sensor outputs a voltage that is proportional to the concentration of smoke/gas. In other words, the relationship between voltage and gas concentration is the following: The greater the gas concentration, the greater the output voltage; The lower the gas concentration, the lower the output voltage; The output can be an analog signal (A0) that can be read with an analog input of the Arduino ...
