Week 1

As the first week assignments Prof. Neil asked us to find a project and sketch it . I always have a feeling that all my projects should be very useful to the community.

The problem I faced

In India there is lot of poor people working in well cleaning and sewage cleaning. These poor people does not have any protection from poisonous gases and lot of people die every year in India. Based on my knowledge there is no such device available for the poor cleaning workers. I finally reached an idea of poisonous gas detecting module for detecting the pollution level.I got this idea after reading an article about such a death in my place.

My Project

The gas sensor module will detect harmful gases to humans. This module have microcontrollers,gas detecting sensors,and indicators,buzzer etc. I am only in an initial stage and I have to work on its design ,electronics and unit which detects the poisonous gases. Different gas sensors are used to sense gases. This unit is dropped to the well. This unit is connected to the main unit through serial connector. The main unit receive the message from the sensor unit and then displays appropriate messages on the LCD screen. It also produce warning lights and sounds.
As part of this project I have to design Two 3D printed boxes. The Display, Sensor, Microcontroller boards etc will be put inside these boxes. PCB for sensor module and display module. PCB inside the sensor module connects all sensors to the Microcontroller. PCB inside the display module connects the micro controller to display, buzzer and LED Design code to run the sensor module and display module.This will be only a prototype .If it is possible to make the device in the fab lab it will be very helpful for poor people
