Leon Davis –
I like the affordability, and the app lets me monitor CO2 levels and temperature in my indoor garden when the lights are turned off.
Rich –
This device charges its battery and gets power from a USB-C port (nice work!). This means that it must be plugged in at all times if it is to be used continuously.
It also has the added benefit of being able to read remotely via a smartphone app.
The temperature and humidity readings matched those of my other, more trustworthy sensors. To acquire a decent CO2 reading, I let the gadget self-calibrate for 24 hours, and it agreed with my other CO2 detectors.
Bottom Line: A reliable CO2 sensor for your house that you can read on your smartphone and see from across the room.
