A group of 3 Thai students from Kanthararom School, Thailand,
• Chainarong Kaewwichai (second from left)
• Thanakorn Waraput (third from left)
• Yardpiroon Pha-iddee (right)
under supervised by Mr. Satapisat Kraisee (left) and Mr. Narongporn Laosrisin, have built “Smart helmet” for the motorcyclist. This project won the first prize of “Bridge 2 inventor challenge 2016” contest, Bangkok, Thailand.
Mr. Narongporn Laosrisin (Advisor for application development)
The technology behind this project are Arduino and Thunkable!
Arduino board is programmed to monitor 3 sensors
- CO2 level (install in the helmet)
- Heart rate (install in the helmet)
- Triple axis accelerometer sensor (install on the motorcycle, to detect sudden change in 3-axis caused by accident)
Once accident is detected, arduino board will communicate back to android app on smart phone.
Arduino board connected with sensors
All circuits are embedded in the helmet. Only 2 sensors shown (CO2 and heart rate monitor)
The students have developed 2 apps using Thunkable.
One is for the motorcyclist and another is for emergency response stuff
On motorcyclist’s side, the app interface with Arduino board via Bluetooth.
When accident occurred, this app will send following data to emergency response center via FirebaseDB.
- current location of accident (lat, long) from Google maps component
- motorcyclist’s info (name, mobile phone number, emergency contact person, blood type, vehicle ID)
- heart rate
- CO2 level
On the emergency response app, new accident information will trig event DataChanged in FirebaseDB (Both apps share the same FirebaseDB). This app will notify stuffs about the accident, then they can locate motorcyclist and accident via Google maps component
App display dialog about new accident just occurred.
Location of accident and motorcyclist info are shown to stuffs and they can use Google Maps App to navigate them that location.
We think this project is a good start to rescue motorcyclist in the accident and could save more lives.
