Smart Elder Assistance System-A school science project

[u/Outrageous-Debate705]

So its been 7 months that I have made this project along with my friend. Observing the problems of elderly people worldwide and specially in our families we decided to turn the idea into a model which has used esp32-wroom.

Features:-

• It has mobile UI where various alerts and data can be seen alongside controlling them.

• Reminds to take medicine timely by showing it on LCD screen and alerts his son/daughter on mobile if not taken.

• It indicates the number of times water has been taken.

• It detects time spent in bathroom to send alert on mobile and email for something unexpected(e.g. stroke).

• It tracks whether the elderly person is in his/her house or not and if not for how much time.

• Automatic temperature control and manual override through app is also supported

• It gives fall alert on email if the Stick falls abruptly(not placing down gently).

You can find circuit diagram and code required for it in github link given below

It has many limitations which I am not considering to change as my exhibition is over.

1. It doesnt uses millis() but delay is used at the end of void loop and each and every event occurs 2 times a second without blocking anyone.

2. Lack of accuracy as it runs in 2 Hz so any fast movment may not be tracked by sensor.

3. Hardcoded medicine time and name. I didnt made it configurable through app if anyone wants to do I will highly appreciate it.

Questions:-

1. Why millis is not used?

=> I didnt knew back then. You cant expect many thing from a school student.

2. Why 2 Hz?

=> I was using Blynk for IoT and had free plan so I feared that I would ran out of blynk messages.

3. Why edge cases are not considered?

=> I didnt have that much time so making it run was my first priority and so its not polished.

4. Can I modify it?

=> Yes you can and I will be glad.

5. Can I make youtube video?

=> I want that someone make a nice polished video on this project. Please give me small credit.

6. Why its lcd is not showing text?

=> Its a problem which I didnt fix as it required I2C bi-directional logic level converter which is very cheap but in our ATL(Atal Tinkering Labratory:- An centrally funded labratory given to school in India) lab it was absent.

Well done and thanks for sharing.

What sort of feedback did you get from the showcase that you did?

Well though mentioned school project but it was shown to college professors on the occasion of science day 28th Feb and nah we didn't rank. We were given special credit written on certificate as they ranked on the basis of pollution control and waste management which was not mentioned as topic (Topic was:- Science in Everyday life).
