Ecowitt WS90 7-in-1 weather station

Ecowitt WS90 7-in-1 Weather Station

The Ecowitt WS90 is an advanced, solid-state weather sensor array designed to provide accurate, real-world meteorological insights. By eliminating moving parts, this device offers a low-maintenance solution for monitoring local climate conditions without the typical wear and tear of mechanical sensors. It is engineered to withstand harsh outdoor environments and features an IPX5 waterproof rating.

Core Sensor Capabilities

The WS90 integrates seven distinct measurement tools into a single, compact housing.

• Ultrasonic Wind Sensing: Measures wind speed, gust speed, and wind direction using ultrasonic technology instead of traditional rotating cups.

• Haptic Rain Detection: Utilizes a piezoelectric sensor to detect rainfall instantly, offering a reliable alternative to mechanical tipping-bucket rain gauges.

• Environmental Tracking: Monitors outdoor temperature, ambient humidity, and barometric pressure trends to help forecast local weather changes.

• Solar and UV Measurement: Tracks solar light intensity and the UV index, providing valuable data for gardening or smart home energy automation.

• Power System: Operates on a built-in solar panel with dual AA lithium battery backup to ensure continuous operation.

• Winter Operation: Features a built-in heat plate to melt snow and ice when ambient temperatures drop below -3°C (requires a separate 12V DC power supply for activation).

Connectivity and Automation

The WS90 supports broad smart home integration and is fully compatible with the Shelly ecosystem. It features dual connectivity, utilizing both Bluetooth 5 Low Energy and Zigbee 802.15.4 protocols to communicate simultaneously with compatible smart home gateways. This continuous connection allows the weather station to trigger localized home automations, such as disabling irrigation systems when rain is detected or closing window blinds during periods of high solar radiation.
