Story

BACKGROUND

So we started off with looking for some interesting and a useful project that need to be made, we did many research and at the end we got the idea for making this project. As one of our teammate has to do much effort to hide and smoke cigarette, so this device can be helpful for his parents 😂 Imagine having this device all over your house 😂. Also we can use it near gas pipes in kitchen in case of any emergency we could get alert.

BEGINING

So our next step was to make a list of equipment required, after that we went for an online search looking for the sensors but we were able to find em from nearby local shop. Afterwards we started working on the code and circuit of the system. within 2-3 days we completely were able to get it in working position 😎.

HERE IS WHAT THE CIRCUIT LOOKS LIKE!

Code is given below, we tried it on GRANDEUR, GRANDEUR is more preferred due to more choice of selection and vast options according to your choice.

VIDEO OF THE CIRCUIT :

WORKING

Where As the working is considered, whenever the smoke level rises above 400, the buzzer starts beeping and we can see the live update on web or app via cloud.

HERE IS A PICTURE FOR THE WORKING ON THE WEB GRANDEUR:

CONCLUSION

This was all from our side, it is an interesting to make device and you can make it by yourself easily, we can also give it some sort of design and a box so that it can be used commercially. As a Final Decision, i can say that Grandeur provides more easy way to setup your device online. !!!
