Kaa application based on Raspberry Pi and DHT11 sensor
A sample IoT application that collects temperature data from a DHT11 sensor on Raspberry Pi and stores it in Cassandra using the Kaa platform.
Overview
This project demonstrates an Internet of Things (IoT) use case where a Raspberry Pi device equipped with a DHT11 sensor collects temperature and humidity measurements. The data is uploaded and stored in Apache Cassandra using the Kaa IoT middleware platform, showcasing a complete edge-to-cloud data pipeline.
Key Features
- Sensor Data Collection — Reads temperature and humidity measurements from a DHT11 sensor connected to a Raspberry Pi.
- Kaa Platform Integration — Uses the Kaa open-source IoT platform to handle device management and data ingestion.
- Cassandra Storage — Stores collected sensor data in Apache Cassandra for scalable time-series data persistence.
- Raspberry Pi Deployment — Provides complete setup and build instructions for running on Raspberry Pi hardware.
- C SDK Implementation — Implements the client application using Kaa's C SDK for resource-constrained environments.
Philosophy
The project exemplifies practical IoT implementation by combining affordable hardware (Raspberry Pi, DHT11 sensor) with robust open-source software (Kaa, Cassandra) to create a functional temperature monitoring system.
