CO2 gas sensor and solenoid valve - Sensors - Arduino Forum

2021-05-06· Hi everyone, I am working on a project in my lab and need to create a system that will open a gas valve when the CO2 level is below a certain level, and to shut the valve when the CO2 rises above this level. So far I have gotten the arduino and vernier sensor interface shield to read the CO2 levels, but when adding a motor shield into the mix, the CO2 can no longer be read.

CO2 Gas Sensor Problems - Sensors - Arduino Forum

2021-05-06· Using Arduino. Sensors. circuitdh January 5, 2016, 5:11am #1. I am also having a problem!! I recently bought a mg811 co2 gas sensor from sandbox electronics for a science fair project and have been having some problems with it. I burned it in for 2 days and allowed 2 hours for it to heat up but the readings either jump around, are very inaccurate or steadily climb! The calibrated it properly ...

cozir co2 sensor - Sensors - Arduino Forum

2021-06-12· Hello, until recently i used the library and code from this post Arduino Forum, and it worked great. When I decided to calibrate the cozir (GC 009) sensor on fresh air the sensor started displaying a two digit number, earlier when everything was ok it always displayed a three digit number displayed in ppm. I tried posting this question in this post but it doesn't allow me. I would be very ...

Water salinity measurements by sensors - Arduino

2021-05-05· CO2 Gas Sensor - Vernier. The CO2 Gas Sensor measures gaseous carbon dioxide in two ranges–0 to 10,000 ppm and 0 to 100,000 ppm. If you want carbon dioxide gas, it’s good to go, with a range of <100 to >10,000 ppm. If you want dissolved CO 2, then you will need to acidify the sample to bring the carbon dioxide out of solution. This is the most tricky of these four analyses. Vernier ...

O2 Analyzer - Sensors - Arduino Forum

2021-05-06· My very first exploration of op-amps was amplifying the signal from a CO2 sensor (also with an output of millivolts), cause I figured I could do it better than Vernier. As it turns out, I ended up using a two-stage, precision amplifier, but this one worked! I got the voltage range up into the 0-4 volt range, which I could then use to run a display with an Arduino: I think op-amps are one of ...

Ethanol Sensor User Manual – Vernier

The Vernier Ethanol Sensor uses a metal oxide semiconductor to detect ethanol concentrations in the air. The ethanol vapor reacts with the metal oxide and is consumed in a combustion reaction which reduces the internal resistance of the sensor element. An amplifier is used to convert the change in sensor resistance to a response voltage, which is converted into an appropriate ethanol ...
