Tried many non-expensive weather sensors: dht11, dht22, bmp180, bmp280. This sensor, si7021, has the best precission, when you measure the temperature. Dht22 is also has good precission, but the si7021 is a little bit better. Also, it has low power consumption.

Pros: - used the version with a PTFE cover - small size Cons: - correct schematic and BOM is not easily available (comes in really handy if de-soldering voltage regulator, level shifter and pullups) It works as advertised, in the end its a simple circuit, not much should go wrong. I have few of those working for about a month now, no issues.

Very good product for measure temperature and humidity. I Used DHT22 before and after short time or too high weather change it was decalibrated. But this Si7021 module are more stable and have more precise measurement. Differece to measure with professional meter was 1% so very good.
