The Smart Safety Jacket

Introduction: The Smart Safety Jacket

In this Instructable, I will be showing you how to make your own Safety Smart Jacket.

We will use the NodeMCU micro controller and various sensors for proper monitoring of the person's surrounding physical conditions.The objective here is to fit various sensors to the safety jacket to keep track and then send the following data to a website where all the data can be read by individuals.

It has also an alert Buzzer which rings when any sort of gas is detected and a button for sending an SOS signal to the receiver.

Keywords— GPS, humidity, Internet Protocol, Temperature, wireless communication.

It's very easy to make it!
So, let's get started!


Step 1: What You Will Need

For this project you will need:

  • Safety jacket
  • NodeMCU
  • GPS module
  • Touch Sensor
  • Humidity sensor (DHT11)
  • Buzzer
  • Gas Sensor
  • BMP180
  • PCB Board

Tools :

  • Connecting Wires
  • Soldering Machine
  • Hot glue gun (optional)
  • Scissors, Glue and Tapes

Power :

We will use a small power bank/any portable power source for easy handling.

Step 2: Preparing the Circuit

The following circuit can be made by following up the given circuit diagram. Breadboards can also be used in place of PCB boards by beginners.

Step 3: Putting the Hardware Parts Together

Solder the circuit as shown in the above circuit Diagram.

Tip: Test your components well before implementing it on the circuit.

Now,its time to connect the nodeMCU with the following circuit and apply the power supply to it as well.

Step 4: The Code

The code for the given Project is given here.

Make sure that you have the NodeMCU board added to your Arduino IDE. Then select the NodeMCU board and upload the code to the Micro Controller.

Step 5: Placing the Circuit in the Jacket

Carefully make different holes for the sensors and either glue stick it or tape it according to your preferences.

Step 6: Well Done !

Now you have your own Wireless Safety Jacket !!!
