Services

Need a console to use.

Compatible gateways / consoles (Wi-Fi and/or Cellular):  GW1100/GW1200/GW2000/GW3000/WS6210/HP2550/HP2560/HP3500/WS3800/WS3820/WS3900/WS3910/WN1920/WN1980/WN1820/WN1821/WN1900/WN1910/WN1700

Note: 
1. The sensor may share the same channels with other sensors of the same type.

2. Some data is cloud-only and not available on compatible consoles.

3. Compatibility may change with product updates. Please refer to the latest compatibility table(at the bottom of the product page) or contact us for confirmation.

4. Pole not included, pole diameter size recommendation: 1 inch (25.4mm).

WS90 Sensor Array Winter Use Recommendation: For reliable operation in frost and snowy conditions, we recommend purchasing the optional 12V extension cord power supply (sold separately). It can both heat and act as a power supply, but please note the following points:

1. We recommend our customers use a 12V power supply because there is a heating plate inside the battery compartment of WS90, the purpose of the heating plate is to melt the snow covering the battery compartment (snow will affect the wind speed measurement). Moreover, with a 12V power supply, the power cable can be stretched longer. 

2. Be sure to pay attention!!! The supply voltage range can only be 5~20V, more than that will be very dangerous and will cause damage to the WS90.
