Review on 🌡 Veanic 4-Pack Mini Digital Thermometer Hygrometer Meters Gauge - Large Number Display, Fahrenheit Temperature (℉), Humidity for Home, Office, Humidors, Jars, Incubators, Guitar Cases by Sean Purnomo

UPDATE: Of course, as the temperature rises above 74°F, the accuracy of the humidity sensor will start to decrease. I have two other humidity sensors and they have always been accurate. Every 4 at 78+ or higher the moisture readings will vary more and more, up to 10%. This is 100% unacceptable and renders these sensors useless. Alternatively, it's not as small but accurate, the AcuRite 00613 digital hygrometer and room thermometer is only $13 and even stores a history of highs and lows. After reading the reviews (all 1 star) I was suspicious of the accuracy of these little modules. Delivery was excellent and packaging was secure. The results are available after several days of testing. Two out of four differ from one point in humidity. The temperatures are stable. Now the next test is how long they last with the included batteries.
