Lark Weather Station - Classroom STEM Kit for Arduino / micro:bit / ESP32

The Lark Weather Station is an all-in-one meteorological kit designed for STEM classrooms, field experiments, and student science projects. It captures key environmental data straight out of the box without complicated wiring, making it ideal for middle and high school learners exploring data science and coding. Compatible with micro:bit, Arduino, ESP32, and Raspberry Pi, it supports both standalone data logging and connected IoT applications.

Five-element environmental sensing

The station integrates sensors to accurately measure wind speed, eight-direction wind heading, temperature, relative humidity, and barometric pressure. Readings are output in standard physical units for direct interpretation without complex calibration.

Dual I2C and UART communication

Real-time data streams effortlessly across either I2C or UART communication modes. This standardised data output simplifies code development and allows instant integration with school robotics platforms.

Broad microcontroller compatibility

The unit connects seamlessly to micro:bit, Arduino, ESP32, Raspberry Pi, and UNIHIKER boards. It also pairs directly with the Gravity Science Data Acquisition Module for instant screen-based readouts without programming.

Integrated 16MB offline storage

Equipped with 16MB of built-in storage, the station can store up to 160 days of meteorological data recorded at one-minute intervals. Recorded files save in standard CSV table format and export directly to a computer via USB Type-C.

Compact and portable design

Measuring just 160 by 55mm with a detachable wind vane, the station easily fits into field packs or sits neatly on a student desk. Its lightweight 270g profile enables effortless transition between classroom demonstrations and outdoor investigations.

Standard tripod mounting socket

A standard 1/4-inch threaded port on the bottom allows the unit to secure onto standard photography and lab tripods. An adjustable desktop tripod is included in the kit for quick classroom benchtop setup.

Durable weather-resistant build

Constructed with an all-metal exterior and a protective waterproof coating over the internal circuitry, the hardware is built to endure outdoor educational use. The bottom Type-C and Gravity interface ports should be shielded from standing rainwater during wet-weather deployments.

Flexible standalone and IoT deployment

Use the device as a self-contained data logger powered by a 5V source, a handheld meter in the field, or an online IoT weather station connected to a Wi-Fi-enabled controller. It serves as a practical testbed for teaching Python, C++, and environmental science.
