Problem with MG811 CO2 Sensor : arduino

Problem with MG811 CO2 Sensor. Close. 1. Posted by 2 days ago. Problem with MG811 CO2 Sensor. I tried the code below, and it works. However, when I am about to unplug and replug the Arduino, the value is no longer accurate. It received both a high value more like 20000+ and a negative value. What is the reason for this? When I press the Arduino''s builtin reset button, the value will be ...

How to use MG811 Sensors Arduino Forum

06/05/2021· Hi. I got the sensor MG811 that senses carbon dioxide, you can see an image of the sensor here I googled to use that sensor properly but i have doubts about the wiring with arduino and the proper way to calibrating. So, i got think i can got the data from AOUT pin, but i really don''t know if i can use the 5V pin from arduino to connect in vdd or i need another source (around 12V).

Aquarium Control Monitoring Arduino Project Hub

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 and room. So far so good. The interesting part of the project is still to come: the time intervals, relay controls and sensors data are driven and stored by a PC running Linux and NodeJS server. The server stores sensor data in a database and ...
