Raspberry PI Java Sensor Library

This is a library for Java Sensors. You can use it as Maven dependency.

This blog post describe who it started and how I used it in my IoT AirQuality Lab project.

To test it, you can use the examples.

Sensor Libraries:

  • BMP180 barometric sensor
  • BMP280 barometric sensor
  • Seed Studio AirQuality Sensor 1.0/1.3 indoor air quality
  • SHT15 humidity sensor
  • TSL45315 light sensor

Using examples

Compile and package can be done on a seperate computer or on a Raspberry Pi itself.

 cd rpi-java-sensor-lib
 mvn package

The package command generates a examples/target/examples-1.0-SNAPSHOT-jar-with-dependencies.jar.

If you have packaged on the Raspberry Pi you can use it direct, otherwise you need to copy it to the Raspberry Pi. ddd Use this commands to test the Sensors:

sudo java -cp examples-1.0-SNAPSHOT-jar-with-dependencies.jar de.patricksteinert.rpisensorlib.examples.AdafruitBMP180Example
sudo java -cp examples-1.0-SNAPSHOT-jar-with-dependencies.jar de.patricksteinert.rpisensorlib.examples.AdafruitBMP280Example
sudo java -cp examples-1.0-SNAPSHOT-jar-with-dependencies.jar de.patricksteinert.rpisensorlib.examples.Sht15Example
sudo java -cp examples-1.0-SNAPSHOT-jar-with-dependencies.jar de.patricksteinert.rpisensorlib.examples.PollutionSensorADS1015Example
sudo java -cp examples-1.0-SNAPSHOT-jar-with-dependencies.jar de.patricksteinert.rpisensorlib.examples.Tsl45315Example
