Product Description

ECOWITT WH51 Wireless Soil Moisture Sensor Max 8 Channels

• Please do not touch the stone or hard rock soil. The sensor may be damaged if the soil is too hard and dry.
• Designed to measure soil moisture ONLY.
• To get accurate readings, it is recommended that you completely insert the sensor into the soil and leave it in for 2-3 minutes.

• ECOWITT WH51 is only a soil moisture sensor. It can not directly display the soil moisture readout or connect to a mobile phone.
• You need to separately purchase an ECOWITT GW1100/GW1200/GW2000 Wi-Fi gateway or other console display, such as WS3800/WS3900/WN1980/HP3500/HP2551/WN1820/WH0291.

Why Choose Ecowitt Eco-IoT System?

If you own an ecowitt IoT gateway, such as the GW1200/GW2000 or an IoT console, and an IoT sub-device, such as the WFC01 watering timer or AC1100 smart outlet plug, you own an ecowitt IoT system. After setting, other ecowitt sensors' data can be used as trigger conditions to control your IoT device.
