This is a setup to check the moisture quantity in a particular land area. In this prototype, a soil moisture sensor is set upon a vase, and it will check how much moisture is present in that sample. And the result will be displayed in the LCD display.

Step 1: Sensors Used

Here a soil moisture sensor is required. The sensor is REES52. It has dual output mode analog and digital both. And 1 Vcc and 1 Ground. The operating voltage is 3.3-5 V (volt).

Step 2: Hardware: Intel Edision Mounted on an Arduino Breakout Board

The main hardware of this project is Intel Edison mounted on an Arduino Breakout board. Here in the picture Intel Edison board connected with a seed studio Arduino compatible shield is shown.

The specification of this board is:

20 digital input/output pins, including 4 pins as PWM output
6 analog inputs
1 UART (Rx/Tx)
1 I2C
Micro USB device
SD card connector
DC power jack (7 to 15 volt DC input)

The above diagram shows the connection of the complete circuit i.e. the sensor connection with Intel Edison board.

Step 3: Connecting Sensor With the Edison Board

Here in this step the connection of edision with the soil moisture sensor is shown. The soil moisture sensor is connected with A0 pin of the edision. The sensor senses the value and send it to the edision which have intel atom processor. And show the value into the display.

The above diagram shows the detection of moisture level i.e. how sensor got the value from the soil and displayed at the LCD display.
