It would be better if baseline didn’t shift so much.

This is perfect for my home brewery. I have a lot of C02 plumbing through my brewhouse and draft system and this has paid for itself in savings from catching small gas leaks before I lost an entire tank of gas. My wife likes the peace of mind and greater safety of using this since anyone who has suddenly encountered really high CO2 in a small space knows you can't smell in and it's like a punch in the face. This is really easy to use for me, especially with the app I was easily able to put on my phone so that I can monitor CO2 levels and be alerted even remotely. The design size is compact and small, so it easily fits along my wall near my gas tank. I haven't really worried about the battery life as I always keep this plugged into my wall with the included AC adapter and personally, I'd want something I can rely on always providing power, but if power was lost at my home, it's good to know that this device would continue to operate for a while. This is really easy to use and I highly recommend this to anyone who had CO2 hazards in their home or business.

Luego de usarlo por un tiempo, realizo lo útil que es el indicador de CO2.Ayuda a monitorear, identificar y comprender la razones de ciertos síntomas asociados al CO2 en el momento que suben los niveles.Estos síntomas son: dolor de cabeza, agotamiento, sueño, fatiga, dificultad para concentrarse y enfoque, entre otros. Permite tomar acción para bajar los niveles. Como abrir una ventana o prender un abanico para que circule el aire y bajen los niveles de CO2. Excelente producto.

The sensor was constantly going off at over 1500ppm anywhere I put it even outside.

So my wife decided she wanted to go vegan. We started trying to grow mushrooms at home because they are so expensive at the store. Being a home automation guy I just put our blower on a timer to vent the CO2 out. Things weren’t going well bought this and discovered my levels were still too high. After buying a CO2 controller I still needed this to calibrate it. Well worth the cost and easy to use.

I have had this for a few months now and found it very useful.It has current CO2, humidity, temperature, time displays.It has 4 brightness settings, and audible CO2 alarms if they go over certain thresholds, the alarms are mutable by buttons.It has a built in battery that lasts about 8 hours from a full charge, or I keep it plugged in USV-C.The only thing about it I don't like is it does not have mounting holes AND the power jack sticks out in the back making it hard to place up against anything, and the cord makes it hard just keep in place - one star lost for that inconvenience.Very good product otherwise.

Pros:- The display offers three brightness levels.- Temperature and humidity readings closely match those from other reliable devices.-The indicator light changes color based on CO2 levels.- When calibrated manually each week, CO2 levels stay consistent with my other devices.- It includes 18 pages of instructions, though they could benefit from a grammar check.Cons:- The primary concern is with the Automatic Baseline Calibration function. It is always active upon powering on the monitor, designed to calibrate at the lowest CO2 reading detected over a week. The manual reads: "The Automatic Baseline Calibration function is always 'ON' when the monitor is turned on. The Automatic Baseline Calibration is designed to calibrate the monitor at the minimum CO@ reading detected during 7 days of continuour (power on)." While this may work for some, it doesn't work for us.For nine months of the year, we occasionally open windows, bringing indoor CO2 levels down to approximately 400 ppm. However, during cooler months, windows remain closed, and we utilize other Wi-Fi CO2 meters to control our ERV system. The ERV activates when any of our three monitors display levels of 800 ppm or higher, and it shuts off at 750 ppm or lower. In a well-sealed environment with two occupants, CO2 levels sometimes never return to 400 ppm during the 7 day period and can read more than 200 ppm high when it automatically 'calibrates'. If the Automatic Calibration feature could be disabled, this device would be our primary CO2 meter.
