Simple Spring Boot application measuring temperature with a BMP085 sensor.
Features
- A Springboot standalone application measuring temperature and pressure with an BMP085 sensor
- Measured data is sent via MQTT to a RabbitMQ server
- Application is using Spring-Integration 4.1 with annotation based configuration
- A Springboot web application consuming the MQTT data and relaying it via STOMP
- pushing the data via Websocket to the clients
- A Springboot standalone application consuming the MQTT data and writing it to a Google Spreadsheet
Prerequisites
What you need to run the applications:
- Java 8
- RabbitMQ (http://www.http://www.rabbitmq.com)
- RaspberryPI with Java 8 installed and wired BMP085 sensor
- pi4j (http://pi4j.com)
Module description
raspberrypi-boot-bmp085
This is the application meant to run on Raspberry PI, measuring data via BMP085 sensor. In development mode there is a mock implementation generating random data.
Application properties can be configured in
raspberrypi-boot-bmp085/src/main/resources
Use
mvn clean install
to build the application and
java -jar target/raspberrypi-boot-bmp085-0.0.1-SNAPSHOT.jar --spring.profiles.active=dev
mvn spring-boot:run -Dspring.profiles.active=dev
to run it on the development machine.
raspberrypi-boot-server
This is the web application relaying the MQTT data via stomp and pushing it to the clients via Websocket.
Application properties can be configured in
raspberrypi-boot-server/src/main/resources
Use
mvn clean install
to build the application and
mvn springBoot:run -Dspring.profiles.active=dev
to run it.
raspberrypi-boot-gdata
This is the application consuming the MQTT data and writing it to a Google Data Spreadsheet. Please make sure you have an Google Account and downloaded the JSON Credentials file as described in this document
Application properties can be configured in
raspberrypi-boot-gdata/src/main/resources
Use
mvn clean install
to build the application and
mvn springBoot:run -Dspring.profiles.active=dev
to run it.
