This example demonstrates a complete IoT telemetry pipeline where a micro:bit V2 sends temperature and light readings over USB serial to a Python gateway, which forwards them via MQTT to an AWS-hosted Mosquitto broker. The flow continues through Telegraf into InfluxDB, with Prometheus and Grafana for monitoring and visualization. The code uses MicroPython’s `temperature()` and `display.read_light_level()`, plus `pyserial` and `paho-mqtt` for serial communication and MQTT publishing. The architecture is illustrated with a Mermaid flowchart, and the gateway enriches JSON payloads with metadata before transmission.

This visualization documents an IoT and sensor-based academic project. It demonstrates a complete data pipeline where sensor readings are transmitted via MQTT to the Flespi dashboard for real-time monitoring. The example integrates Wokwi circuit simulators, a Raspberry Pi Pico W, and generates UI mockups through Stitch GPT. The repository includes a README with technical architecture details, a Loom video explanation, and a DALL·E-generated cover image. Code is written in Python 3, with sensor data flowing from emulated devices to the cloud dashboard.

This example demonstrates a complete Internet of Things workflow, showing how to collect, store, and visualize sensor data from a smart agriculture scenario. It uses an InfluxDB time-series database running on an Amazon EC2 instance to manage temperature, humidity, luminosity, and soil moisture readings. The data is generated by a Mockaroo CSV export and imported through the InfluxDB CLI, then queried with InfluxQL and the Flux language’s `aggregateWindow` function. The final step renders interactive trend charts in the InfluxDB dashboard, illustrating the full path from raw sensor simulation to analytical visualization.

A Grafana dashboard monitors sensor and infrastructure data in real time, plotting temperature and humidity measurements from an InfluxDB bucket alongside CPU and memory metrics from a Prometheus node exporter. The dashboard merges time-series data from both sources, showing simulated IoT sensor readings injected every five seconds via a Python script and system resource utilization from Prometheus, with all services accessed through a Tailscale virtual private network.

This example shows a Raspberry Pi Pico W microcontroller consulting an AI model to decide on greenhouse ventilation and displaying the response on an OLED screen. It simulates temperature and humidity sensor readings, sends them via the `urequests` library to OpenAI’s Chat Completions API (GPT-3.5-turbo), and renders the AI’s decision on an SSD1306 OLED display using `ssd1306` and the I2C protocol. The code also uses the `network` module to connect to Wi-Fi, with data refreshed every 15 seconds.

This visualization presents a collection of 45 practical exercises for the micro:bit V2, a microcontroller, designed for educational and prototyping purposes. The dataset is a markdown list of activities, each detailing a project that uses sensors for data acquisition and radio communication for transmission. The projects span categories like sports, classroom, environmental science, and STEM, showing how the physical device can be used to graph data. The text shows the projects are intended for graphing events and for creating a radio transmitter between micro:bits to acquire or transmit data, with no code or libraries used in the rendering.

MQTT Generator Script

This example demonstrates a script that generates simulated sensor data and publishes it to an MQTT broker. It functions as a data source for dashboards, creating random readings within configured ranges for multiple named sensors, each with geographic coordinates, units, and descriptions. The Python 3 script uses the `paho-mqtt` library to connect and publish JSON payloads to a specified topic at a configurable interval. It reads sensor definitions and broker settings from a `config.json` file, allowing users to add or modify sensors without changing the code. The script selects a sensor at random for each message, producing a continuous stream of test data for visualization or IoT development.

This example shows a MicroPython learning activity where an ESP32 or Raspberry Pi Pico W sends prompts to the OpenAI ChatGPT API and displays the text response on an SSD1306 OLED display via I²C. The code uses `network.WLAN` for Wi-Fi connectivity, `urequests.post` to call the chat completions endpoint, and `SSD1306_I2C` from the `ssd1306` library to render the reply. The demonstration includes connection setup, JSON response parsing, and a simple text-wrapping routine for the OLED’s 16-character line width, with optional scroll or truncation for longer answers.

Micribit in 6 programming languages

This example showcases a multi-language IoT data reader system, demonstrating how six different programming languages—Python, C#, C++, Rust, Node.js, and Go—implement serial communication with a micro:bit device. The visualization compares the data parsing and alert detection across these languages while displaying real-time JSON sensor readings. The system processes temperature, accelerometer, light, and battery voltage data transmitted every 0.5 seconds via USB serial. Each language implementation uses its respective serial port libraries and JSON parsing modules, with the micro:bit running MicroPython's JSON and accelerometer APIs, while the overall architecture highlights protocol handling and error management differences between the programming languages.
