Testing of the soil humidity sensor with raspberry pi

1. Soil Moisture Sensor
With Raspberry Pi
Biplaba Samantaray

2. OUR AIM IOT CONCEPTS
 To introduce the primary concepts about the
sensors .
 How the Raspberry Pi works with sensors
 Describe the piece of Python code we are
using for the execution
 Show the Execution of the Soil Moisture
sensor .
The Soil Moisture Sensor
We will Show the brief idea about the soil moisture
sensor , Its need, how it works ,Where we are using this sensor
and which version of the sensor we are using .

3. We are Using 1

5. THE TOOL WE ARE USING

6. Hard Ware Explanation

7. The Sensor
A sensor is a device that detects and
responds to some type of input from
the physical environment. The specific
input could be light, heat, motion,
moisture, pressure, or any one of a
great number of other environmental
phenomena. The output is generally a
signal that is converted to human-
readable display at the sensor location
or transmitted electronically over a
network for reading or further
processing.
The Soil Moisture Sensor
Soil moisture sensors measure the volumetric water content in
soil.
Associate with property of the soil, such as electrical resistance,
dielectric constant, or interaction with neutrons, as a proxy for
the moisture content.
Application
 Agriculture
