**SMART ENVIRONMENT MONITORING DEVICE**

INTRODUCTION

A Multithreaded Application for BeagleBone Green (Linux) using two offboard sensors (Temperature sensor & Light sensor). The project consists of 5 threads in total. There is 1 parent thread which is the main task. The main task spawns 4 threads, namely Temperature Thread, Light Thread, Socket Thread and Logger Thread.

Main Thread: This thread/task is responsible to keep a check on all of its child threads(ALIVE/DEAD).If the main thread dies or is terminated, it gracefully closes all the threads and terminates the program. Temperature Thread: This thread/task is responsible for communicating with the TMP102 temperature sensor. Light Thread: This thread/task is responsible for communicating with the APDS9301 light sensor. Socket Thread: This thread/task is responsible for connecting with remote clients in order to provide them with Temperature & Lux data as and when requested by the client. Logger Thread: This thread/task is responsible for logging all the data/error messages/debug messages/information messages to a log file.
