Attention: WS90 outdoor weather station unit products have more technology to improve, because of high sensitivity, so the wind blowing, and light rain can cause data fluctuations, exist the inaccurate data. If you have high requirements for data accuracy, we suggest you buy wh40 and compare it with ws90 to make correction values.
If there are no precise requirements for each rainfall data, then WS90 is fine.
