This Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor.Let Your plants reach out for your help when needed. They can be very easy to use, just insert it into the soil and then read it. With the help of this sensor, it will be realizable to make the plant remind you : hey, i am thirsty now, please give me some water.
1.Connect the VCC pin from sensor to 5Volt DC pin of Arduino.
2.Connect the GND pin from sensor to GND of Arduino.
3.Connect the signal to Arduino Pro mini's A6 Pin (Analog 6 - measures analog variance in voltage).
4.Insert it to soil.
5.Connect FTDI board to Arduino Pro mini.
6.Connect FTDI Board to computer via mini USB Cable.
7.Upload the code Moisture_meter_calib.ino
8.After successful upload fire up the serial monitor to see the results. (Here's how to open a serial monitor
9. keep a note of results from different soil conditions as they will be used as determining conditions in later version of code for our final project compilation.
