🌡️ 2PCS Mini Digital Hygrometer Thermometer: Accurate Indoor Humidity Monitor for Humidors, Greenhouse, Garden & More Review

If they ever die or run out of extra batteries I'll buy the same ones for replacements. I just changed the batteries in one and have been using it for 11 months now. The one with weak batteries worked overtime. It's in the basement. In Florida. On the waterfront. So it showed 99% humidity the whole time. The poor thing must be just as exhausted and overheated as me! I have another set of batteries and the other gauge still works. I can't remember the last $5 I spent as long as this pair of…

I have ordered (2) packs of hygrometers/temp sensors for each of my machines. I decided to test their accuracy on other digital weather sensors I have at home and on each other. I installed 2 near the central weather unit for comparison and let them stabilize for 3 days. I have provided a comparison photo. The difference values to each other are 0.3 degrees Fahrenheit and 2%. The difference of 2%, 40% and 42% is not within the given +/- 2%. The 40% hygrometer reading versus my home weather…

EDIT: My infrared heat gun deflected them 1-2 degrees. Not enough to make a difference whether you're using them to gauge growing plants or maintain temperature in a pet terrarium or similar function, but it's worth mentioning. Either that or the heat gun is off. I have no way of calibrating to know which one is 100% perfect. Original post: I can't confirm the accuracy but having used it at home for the past few weeks I would say the temperatures are accurate. Both show almost the same for…
