This video is around Raspberry Pi to showcase the usage of Raspberry Pi in IOT projects and that's using JAVA. This is going to be a series of video including Sensor interfacing using pi4J, REST API usage with JAVA, MQTT usage with JAVA and finally adding all to the same project and running over Raspberry Pi. In the last video, we saw how to interface DS18B20 1 wire temperature sensor with Raspberry Pi by using JAVA. If you have not checked it out you can do that and for that, I have provided the link down below in the description. This video is the 2nd in the series where we will see how to publish or send sensor data using REST API to cloud. And in this, we are using ThingSpeak as cloud service to publish data. HTTP calls for REST API are done using Unirest lightweight HTTP client library. In the next video, we will do the same by using MQTT.
