## Description

desertcart.com: CO2 Meter Portable CO2 Detector Digital CO2 Monitor with Alarm Function Carbon Dioxide Temperature and Humidity Meter, NDIR CO2 Sensor Indoor Air Quality Monitor for Home Office Grow Room : Industrial & Scientific

Review: Handy Meter - I have been having what I assume is an exhaust leak in my car. However I have a very sensitive sense of smell and I didn't want to spend a lot of my time and effort fixing what may be a very small problem. Initially I tried a CO meter however the meter itself was defective. On further investigation I determined that a CO meter was not what I needed anyway. Most modern cars do not output very much CO at all. The catalytic converter converts most CO to CO2 or water. Also, trying to detect CO means detecting a few parts per million. That's difficult. With a CO2 meter it's much easier because any decent sized exhaust leak will VERY quickly spike the CO2 levels in the car. Also, the measurements will be in the 1000s of parts per million so the error range of the meter is less important. In short, if you're looking for exhaust leaks in vehicles it will likely be easier with a CO2 meter as car exhaust is chock full of CO2. On to this meter, it works very well. I tested it in a number of situations and it detected the amount of CO2 that i would expect it to. The manual states that it samples the air once a second and as far as i can tell this is accurate. However, it is not meant to precisely measure the CO2 concentration every second. The sensor takes time to accurately reflect the ambient CO2 level. This is easy enough to test by breathing briefly on the sensor which will cause it to easily jump to over 5000ppm but it will take 30 or more seconds to return to normal. In my own car I found that the CO2 level was no different from my friend's car. So whatever I'm smelling on hard acceleration it is very likely not exhaust gases or is such a tiny amount that it's not adding to CO2 levels. That is a helpful thing for me to know. Further, this meter has applications beyond just testing the cabin of a car. It can also be used in buildings to determine if the amount of ventilation is adequate. Also, it can be used in the home to see if CO2 levels are too high (as can occur particularly when cooking or using a fireplace). I was surprised to see that in both my car and my friend's car, with the air on recirculate, we reached over 1500ppm in just a few minutes. It comes in a cute carrying case that looks like a tiny plastic briefcase. I can't imagine I'd ever use it but if you want to look like a real "pro" it can't hurt to have your meter in it's own case.
Review: So easy to use - Love how this helps us locate co2 leaks.

### ⭐⭐⭐⭐⭐ So easy to use

Love how this helps us locate co2 leaks.

### ⭐⭐⭐⭐ Not standard UART
*by M***N on May 16, 2022*

I bought this meter for its simplicity and power in and serial connections. I plan to use it as a safety alarm in enclosed spaces as well as a hobby scientific tool data logging to my computer. Unfortunately the serial connection does not work with standard USB/UART adapters such as FTDI. In fact, when I plugged in my oscilloscope there was no signal at all. You have to buy their special adapter to get data logging output, and they only provide software for Windows computers. Their manual does specify connection parameters and data format so there is hope I can do some reverse engineering. I have no other meters to compare accuracy but the readings seem reasonable. Build quality is decent: not highly ruggedized but chunky enough that I expect it to survive a couple of accidental drops. Overall not a bad tool but I waited for a good deal on a used one.
