IoT based security system that detects suspicious movements through a motion detector and alerts the user on their gmail. In the presence of motion sensed between 7 to 9 times, the Grove PIR sensor sends an input to the board which is connected to internet via Ethernet. The board publishes the sensor data on IBM IoT foundation, which is known as IBM Watson. The data is then sent to IBM Bluemix which provides real time analysis and the remote time data management and monitoring.
