This blog shows how to control your MQTT client by sending commands to it on the MQTT topic known as the commands channel in RAPIFIRE. This LogErrorsPublisherCmd class to allow you to remotely turn on/off publishing and to update the filter word from "Exceptions" to any new value such
This blog describes using an Arduino Yun with PIR Motion Sensor (JST) SEN-13285 ROHS to create a smart barn motion detector app using RAPIFIRE. It can be used to notify a farmer that an animal such as a horse or cow is in their stall or not, based on detecting
RAPIFIRE provides an HTTP automation API for efficiently managing in bulk many Iot Things. This example will use Apache's HttpComponents to call the API to create 100 thermometer things and users. The java class for this example assigns each user to a thermometer thing and sets the meta data of
What is Machine Learning?
Machine learning is a subfield of computer science that evolved from the study of pattern recognition and computational learning theory in artificial intelligence. Machine learning is very useful in IoT since it can be used to learn hidden relationships in the Big Data which flows in
In this blog we cover building an IoT app for monitoring too much noise in a classroom using a simple sound sensor with the Ardino Yun and RAPIFIRE. When the noise sensor detects the sound is too high due to students misbehaving it sends a message to the the School
