I need extra sensors like vibration sensor, water level sensor, etc.
From where I can get these?

You can easily get these sensors online… But you may be able to make a water level sensor your self… Take a wire from 3v3 and stick an open wire end at the bottom of container and one wire from GNDv to a small resistor at one end… connect the other end to A0 and another wire from the A0 end of resistor and stick it to the desired level you would like to sense… now when the water reaches that level the analogRead(“A0”) will give you a reading or else it will be 0

Though you get some of the sensors in the kit.But for making more awesome and cool projects you will obviously need more sensors.Sensors helps us in making our project simple.You may get the required sensors online on websites like amazon,flipkart,ebay etc.Or you may buy it from local electrical shops too or maybe as a challenge you can create some of the sensors at home.
