Review on 🌡️ Inkbird ITH-20R Wireless Receiver Digital Hygrometer Thermometer - Accurate Temperature Display for House, Kitchen, Baby Room, Courtyard, Brewhouse, Public Places - Rainproof Function, Indoor/Outdoor Use by Joshua Vogel

Accuracy: Two modules sat side by side on the counter for a few days prior to installation. At times they showed a temperature deviation of about 0.3 degrees Celsius (you can switch to Fahrenheit) as well as a slight difference in humidity. Of course, these deviations can be attributed to the fact that the internal module does not have to "send" its current measured values - in contrast to the external module. Ease of Use: I've used a thermometer to monitor the temperature in my cold frame and so far it's working well. I haven't used the extra sensor yet (with a wire to connect to the outdoor unit) as I was able to carefully position the unit just off the ground, but that might be something I'll do later this spring when temperatures and more are important - Humidity increases. The 24h-min-max recordings are particularly helpful for my cold application of this thermometer. This allows me to see the lowest temperature (and humidity) in the fridge over the previous night (as well as the highest reading). Please note that the device will be shipped without batteries. I used batteries.
