PIOT-INF-04-001: Data Emulation

[labbenchstudios]

Review

Read Chapter 4 of Programming the Internet of Things.

Objective

Following the design principles from Chapter 3, use the SenseHAT emulator application to build real sensing and actuation functionality into your CDA.

Optional Objective

Deploy your CDA to a Raspberry Pi and talk to the I2C bus and GPIO.

Activities

Integrate your CDA functionality from PIOT-INF-03-001 with (a) the Sense HAT emulator - sense-emu - and, optionally, (b) actual IoT hardware. While this latter step is optional, it is useful for understanding how to pull data from an actual sensor and trigger an action on a real actuator.

Lab Module 04

Lab Module 04 - Data Emulation is focused on building the components that will work with a software emulator (Sense HAT Emulator) to dynamically generate time-series sensor data, such as temperature, humidity and pressure. This will also introduce the concept of emulated actuation, where the Sense HAT Emulator's LED display can be activated via an actuation command.

Step 1: Read the Lab Module Summary and follow the Configuration steps
