Description

Prototype 1 - A 4WD semi-autonomous rover that would drive around the city on and off road detecting pollution levels using onboard sensors such as Shinyei PPD42 Particulate Matter Detector, MQ-2 Gas Sensor, MQ-9 Gas Sensor, MiCS-2714 Gas Sensor (NO2) MiSC-2614 Gas Sensor (Ozone), Keyes DHT11 Temperature and Humidity Sensor. These sensors collect data from the surrounding of the rover and send it to the base station along with the current coordinates of the rover so that pollution data can be pin-pointed on a map with much more precision than our current satellite based methods. The rover also had an onboard camera to click pictures of pollution sources as for evidence when the government takes action.
Prototype 2 - A smaller version of the detection system which could be fit on the exterior of vehicles such as taxis, trucks etc… as these vehicles have a very large usage and cover maximum. This prototype can be just attached on the exterior of the vehicles to send the same metrics as Prototype 1 but without any visuals.
Prototype 3 - Another smaller version of prototype 1 which is pocket-friendly, the user gets a notification with the pollution metrics and the base station is provided with anonymous location tagged pollution metrics.
Prototype 4 (an idea not prototyped yet)- A drone based pollution surveillance system that conducts random pollution checks and inspections of the city.

Description

A two-wheeler robot that uses A gyroscope (MPU6050) to balance itself. Made using small boxes of the cup as a base.

Skills Developed:

• Utilising Gyroscope library
• Manipulating values from Gyroscope to the servos
• Symmetric contruction of Robot

Description

A farm system which uses humidity sensors to measure the humidity in soil and starts flowing in the water when the humidity goes below a particular level. It had an advantage over other systems as it was way cheaper than the one currently available.
Further improvements in the systemadded ability to monitor the weather through on ground systems and satellite predictions and then estimate the amount of water to be flow to different kinds of crops.

Concepts Utilised

Thank to pop me out of that button, but now i'm done so you can close this window.

Skills Developed:

• Utilisation of Weather Data for further data processing
• Understanding direction of flow of water and power required in different scenarios
• Understanding how water effects soil

Description

A system which is stuck to the walls and uses flex sensors to measure bends which are used to detect any kind of internal damage after earthquakes or any other disaster which could possibly affect the structural strength of the building. Data processed can be checked using a mobile app. Can also be placed under beam bridges to ensure that the bend in the bridge is not too much.

Skills Developed:

• Utilising Flex Library
• How to handle delicate flex sensors
• Weight distrubtion in different types of architectures

Description

A robot that detects objects in paths and changes direction to the safest path around. Uses Ultrasonic Sensor to detect the distance of the nearest obstacle and checks if the distance less than 15 cm if true then it turns its paths around.
The second version uses a servo to check the distance of object left and right, then compares the distance and in the direction with lesser collision chances.

Skills Developed:

• Understandingthe working concept of Ultrasonic Radars
• Understanding how difference in sound interval can be utilised to measure distance
• Controlling Motors using Motor Driver Shield

Description

A project that uses Ultrasonic Sensor to map out the area nearby it. The data received by the sensor is sent to the computer where it is processed by a software namely ‘Processing’ to represent the data in a graphical manner. LIke a radar.

Skills Developed:

• Mount Based Servo Rotation
cv
• Syncing data reading speed to servo rotation speed
• How ti use 'Processing' platform to visualize data
• Collecting data from Serial Port

Description

A system which stops the flow of current to the device until the correct 4 digit password is entered. It prevents possible electric shocks to small children and can even be used to lock the TV or any other device in case you want to stop your children from watching TV too much.

Skills Developed:

• PCB Design
• Restricting AC current using a DC Circuit

Description

A dustbin which detects incoming garbage and opens up its flap. The user does not require touching the dustbin to open the flap thus increasing the chances of the user to throw the dustbin onto the road or anywhere else. This would increase the cleanliness around the dustbin area.

Skills Utilised

• Using Motion based stimuli
• Understanding relation between speed on incoming garbage and speed to open the container lid

Description

This is the advanced version of the Remote Light Control project. The project uses relays to connect to the mains. The NodeMCu connects to the Adafruit IO which receives data from IFTTT. IFTTT Receives data from Google. This means you just say “OK Google Switch on living room light” and it will switch them on”. The project was further advanced to add mobile and computer control. Now it controls almost all the appliances in my house.

Skills Developed:

• Working with Internet of things
• UnderstandingRelay circuits
• Using APIs
• Integrating different services using IFTTT
