BeagleBone Black and BeagleBone Black Wireless are one of the most widely used computer cards in the world, especially for system development. The BeagleBone boards are characterized because they are entirely OpenSource, and this is very pleasing to the developer community. The versatility, performance and availability of this board made it become one of the main targets of IOT2TANGLE.
In this repository you will find explanations and step by step for the development of a system that every certain time interval (which you will set) will collect data from 5 sensors (including internal sensor), this data package will be sent to a special gateway designed by IOT2TANGLE that you will have on the local network, or even on the Raspberry Pi itself! This gateway will be in charge of adding these packages to Tangle Network of IOTA, through Streams.
IOT2TANGLE provides with code to integrate the BeagleBone Black / Wireless and a give set of generic sensors (I2T sensor's stack). These are just suggested sensors and you can always add some other peripherals required by your project, however the sensors listed here are fully compatible and will be automatically detected when you connect them.
It is not necessary to have all the sensors listed here, the code is able to detect which sensors were connected. In the case of not connecting any sensor, the only real data that will be displayed on the Tangle will be the Internal Voltage of BeagleBone Black Wireless.
This is the list of Sensors/Modules that you can connect and it will be recognized immediately:
- BME280 (Bosch) - Temperature, Humidity and Pressure sensor.
- MPU6050 (InvenSense-TDK) - Acelerometer and Gyroscope 6-axis.
- BH1750 (ROHM) - Ambient Light Sensor.
- Generic Adjustable Sound Sensor with digital output (like KY038 Module)
- Also, you can connect a Green LED that blink when the data is sent to the Tangle, and a Red LED that will Blink in a certain way when it detects certain errors (totally optional).
- HTTP-sender (BeagleBone Black and BeagleBone Black Wireless will send the sensors data through HTTP to I2T HTTP Gateway or Keepy
- MQTT-sender (BeagleBone Black and BeagleBone Black Wireless will send the sensors data through MQTT to I2T MQTT Gateway
