Features
- 【Reliable Wireless Soil Moisture Sensor】: Equipped with advanced chip, ECOWITT WH51 wireless soil moisture sensor collect soil moisture data within 72 seconds when totally inserted into the soil. The data can be transmitted via GW1100 Wi-Fi gateway and the live data can be viewed on Ecowitt APP after Wi-Fi configuration done.
- 【Support Pairing with Various Ecowitt Gateway/Consoles】: The GW1200 Gateway supports up to 16 WH51 Soil Moisture Sensors, and the channel name can be edited. When paired with a Weather Station Console(WS3800/3900/3910), up to 16 channels WH51 sensors supported and you can view soil moisture data in real-time on the Display. When paired with Console WH0291, you only can view soil moisture data in real-time on the Display.
- 【Uploading to Ecowitt Weather Server】: Supports uploading to our free Ecowitt weather server(ecowitt.net) to view the soil moisture data graph and download the history records on the website; support setting and receiving email alerts from the server; channel names can be edited on the website; supports remote monitoring with smart phone, laptop, or computer by visiting the website.
- 【Indoor & Outdoor Use】: The IP66 waterproof moisture sensor can be used for indoor & outdoor potted plants, lawn, garden, farm etc. ★ Please Note : ecowitt WH51 soil moisture sensor is designed to measure soil moisture ONLY. Do not touch the stone or hard rock soil. ★
- 【NOTE BEFORE PURCHASE】: Ecowitt WH51 soil moisture sensor could not directly display the soil humidity readout, which can not be used alone. North America:915MHz; Europe:868MHz; Other areas: 433MHz
