ESP32 REST API Sensor Kit - Build Your Own IoT Data Pipeline with Grafana Visualisation

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine building a web server on a tiny microcontroller that any device on your WiFi can query for real-time temperature, humidity, pressure, and timestamped data. You'll create the same architecture used in industrial IoT dashboards. This kit walks you through every step, from wiring sensors to deploying a Grafana dashboard on your laptop.

What You'll Build

A fully functional IoT sensor node: the ESP32 reads DHT22 and BMP280 sensors, logs data with an accurate DS3231 clock to a MicroSD card, and serves a REST API endpoint that returns JSON arrays of recent readings. A Grafana instance on your computer queries this endpoint to plot time series charts - just like a professional environmental monitoring system.

What You'll Learn

• Program a RESTful API server in Arduino IDE using HTTP GET handlers
• Interface multiple I2C and one-wire sensors (BMP280, DS3231, DHT22) simultaneously
• Implement data logging with timestamps on MicroSD card via SPI
• Connect Grafana to an ESP32 data source and build real-time dashboards
