A snowy week in Chisinau: the heater stops ice from distorting wind readings.
Power switches on the WS90 built-in heater, which melts snow and ice off the ultrasonic sensor.
What it is, who it's for, what it does
About this product
This kit pairs a DC 12V/1A mains adaptor with a 20-metre silicone cable for the Ecowitt WS90 ultrasonic weather station (and the WS80). The adaptor plugs into 100–240 V mains and, through the extension lead, feeds the sensor array that normally runs on a solar panel and buffer battery.<br><br>Its main job is to switch on the WS90 built-in heater: it melts snow and ice off the ultrasonic anemometer so wind speed and direction stay accurate even through overcast winter weeks when sunlight is scarce. The cable is silicone, AWG22 gauge, with a 2-pin connection; the sensor-side lead is 1.5 m long.<br><br>Important: the adaptor cannot attach to the sensor array directly, only through the supplied intermediary extension cord.

The adaptor has a 100-240 V 50/60 Hz input and a 12 V output at 1 A. The silicone cable is 20m long, AWG22 gauge, with a 2-pin connection.What exactly does the built-in heater do?
It melts snow and ice off the ultrasonic anemometer so that wind speed and direction data stay accurate through winter.What is the warranty and availability at CasaSmart?
The accessory carries a 24-month warranty. It is currently marked out of stock; CasaSmart specialists can advise on delivery timelines.
