Introduction:

By taking the help of modern engineering and technology we have designed a bluetooth operated water pump which is used in our agriculture. This system is capable of operating the pump remotely by using bluetooth technology. We activate and deactivate the pump through an Android mobile phone.

Components required:

1. Nodemcu
2. Relay driver
3. Pump
4. Bluetooth module

Working:

The HC-05 is a Bluetooth module which enables wireless serial communication between a microcontroller and an android phone. It works by converting data between serial communication and Bluetooth signals. Here we are using it as a remote control. We are controlling a relay driver circuit using an android phone. The relay driver circuit activates the water pump.

Advantage:

We can operate the water pump from a remote distance wirelessly.
