Story

Aim:

To design an automated water sprinkler system which will provide water to the field if the water level goes below the threshold level so that the farmer can see the moisture content using a mobile phone application in real time

Brief Working:

MSP430G2553 launchpad is connected to soil moisture sensor, HC05 Bluetooth and a SPDT relay. As soon as the sensor takes the reading it is fed to microcontroller, which processes the signal and take action as per the program that is fed in to it. The relay gets a trigger signal for switching ON or OFF the pump depending on the current soil moisture level.

Pump is turned ON in case the moisture level is less than the threshold value.

The user can get the real time value of the soil moisture through the moity app which connects with the hardware through bluetooth.

Applications:

By this method we can save a lot of water

It is a cost effective method

It helps the crops to grow in efficient & scientific manner.

Farmers can use this method for proper irrigation their crops.

This device can also be used at homes to water plants.
