Cardiovascular diseases are the number 1 cause of death globally, taking an estimated 17.9 million lives each year.
What it does
- Traoxy is a device that can be worn around the wrist. It comes equipped with an oximeter and heartrate sensor. It has a charging port to charge it when the battery drains.
- The sensor is for remote health monitoring which shows Heart rate and Oxygen levels on an attached OLED screen.
- It provides real-time alerts and warnings. If any abnormal change in the user’s health is observed so that immediate health assistance can be given to them. Alerts and warnings come in the form of text messages to a pre-defined number.
- You can also track your heart rate and oxygen level over a period of time through a mobile app. It shows a graph of heart rate and oxygen levels.
How I built it
- NodeMCU (ESP8266) to connect with WiFi and send sensor data to the web through Thing speak
- MAX301 Oximeter-heartrate sensor module
- Lithium-Ion Battery and charger module
- 0.96inch, 128x64 OLED Screen to display sensor data
- Wires, resistors and other miscellaneous components.
- Thingspeak to control sending messages through Twilio API
- Twilio API to send text messages to give alerts and warnings
- Blynk App to connect to sensor data and show the graphs
Challenges I ran into
It was quite a time-taking task to arrange all the components and get the wirings right. Apart from that testing also took some time.
Accomplishments that we're proud of
It will be a helpful device for people with cardiovascular diseases, patients at hospitals and elderly people. I am happy that it has a significant real-world application.
What I learned
- Connecting IoT devices to ThingSpeak
- Sending text- messages with Twilio API
- Using different sensors and working with NodeMCU
