The Lark Weather Station is a compact, all-in-one portable weather device that measures wind speed, wind direction, temperature, humidity, and air pressure. It supports real-time data output via I2C and UART, making it compatible with Arduino, micro:bit, Raspberry Pi, ESP32, and UNIHIKER controllers.
With built-in 16 MB storage capable of recording 160 days of data (at one-minute intervals), a standard 1/4" tripod mount, and a waterproof-coated circuit board in an all-metal body, the Lark is ideal for classroom teaching, outdoor exploration, and meteorological research.
Key Features
- Five-Element Measurement – Wind speed, wind direction, temperature, humidity, and air pressure
- Dual Communication – I2C and UART output with physical units
- Built-In Storage – 16 MB flash stores up to 160 days of data, exportable via USB-C as CSV
- Wide Compatibility – Works with Arduino, micro:bit, Raspberry Pi, ESP32, and UNIHIKER
- Compact & Portable – About the size of a drink can, with detachable wind vane
- 1/4" Tripod Mount – Standard threaded port for tripods of various sizes
- Waterproof Coating – Circuit board with protective coating in an all-metal enclosure
Specifications
- Working Voltage – 3.3–5.5V DC
- Working Current – 40 mA
- Sleep Current – 2 mA
- Wind Speed – 0.5–12 m/s
- Wind Direction – Eight directions
- Temperature – -20 to 60°C (±0.2°C)

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- ESP32
- ESP32 is a family of low-cost microcontroller chips and modules from Espressif with built-in WiFi and Bluetooth. They support programmable firmware and over-the-air updates, and are commonly programmed with toolchains such as the Arduino core and ESP-IDF.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
- UNIHIKER
- UNIHIKER is a small programmable computer board used in education and maker projects, often connected to external sensors and modules. Compatibility matters because the cable must match the board’s connector type and pin layout.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
