Hi, im going insane trying to find a device that accurately can tell you the temp (in celsius) and humidity. I have asked, and some say, they often aren't calibrated, or can't trust them, etc etc, so I don't know what to do.
I need a device that is ready to use, I have no idea how these chips things work.
The idea is to get baseline readings of temp and humidity in my bedroom before I implement changes like a dehumidifier, or a humidifier as needed. I suspect something is off and I will need adjustments but I want to know the levels before I do any changes.
Im also interested in reading PM2.5 ppm levels, so if the device would be a 3 in 1, that would be great.
Thanks
