The project aims in designing a wearable device which can detect the pollution of water, sound and air using sensors and Arduino nano microcontroller. This project makes a use of Arduino Nano microcontroller the main controlling device of the project. Sound sensor is uses to measure the sound. Turbidity sensor is uses to measure the amount of light that is scattered by the suspended solids in water.PH sensor is uses to measure the water PH levels. Air quality and PM2.5 is uses to measure air pollution. This device works with battery power. All these sensors, OLED and Buzzer is connected to the Microcontroller. Microcontroller will monitor the sensor data will be display on LCD also it will activate the buzzer when the sensor data crosses the set limit. To achieve this task microcontroller loaded program written in embedded C language.

   

 The objectives of the project include:

• Design a portable device to detect air, water and sound pollution.
• Automatic Monitoring air, water and sound pollution using sensors.
• Alert in abnormal condition using Buzzer.
• Visible alerts using LCD display.
• To achieve this task using Arduino NANO microcontroller.

The main building blocks of the project are:

• Battery power supply.
• Arduino Nano microcontroller.
• Sound sensor.
• Air quality sensor.
• Turbidity sensor.
• Ph sensor.
• OLED.
• Buzzer.

Software’s used:

1. Embedded C Language.
2. Arduino IDE studio compiler to write the program.
3.  Express SCH for Circuit design.
