INTRODUCTION
 Modern Agriculture is focused on the use of data acquired through various sources
(historical, geographical and instrumental) in the management of farm activities.
 Smart Agriculture is focused around soil, weather and crop conditions. Given the
importance of weather and irrigation;
 Technologically advanced doesn’t essentially mean that it is a smart system. Smart
systems differentiate themselves through their ability to record the data and make
sense out of it. Smart farming employs hardware (IoT) and BaaS to capture the
data and give actionable insights to manage all the operations on the farm, both
pre and post harvest. The data is organized, accessible all the time and full of data
on every aspect of finance and field operations that can be monitored from
anywhere in the world.

What can I measure with Smart Agriculture / IoT sensors?
Soil Temperature
• Soil temperature is an essential factor in belowground plant
activity, influencing things such as root growth, respiration,
decomposition and mineralisation of nitrogen. Soil temperature
can be estimated by measuring air temperature and other
factors, however, the most accurate measurement is to use a
probe, buried in the soil. Depending on the root structure of the
plan in question, multiple probes can be installed at different
depths. Surface soil temperature can be monitored using a
different type of IoT sensor that uses IR technology.

Soil Moisture
The moisture content of soil can also be monitored using buried
probes with electrodes. In hydrology, soil science and agricultural –
soil moisture content plays a vital role in soil chemistry, plant
growth and groundwater recharge. Soil moisture content is
essential for several reasons:
 Water in the soil serves as a critical nutrient for all
crops and plants.
 Water is an essential component of photosynthesis.
 Crop yield is heavily influenced by the availability of
water in the soil.
 Soil water is an important carrier of soluble food
nutrients for plant growth.
 Soil water helps regulate soil temperatures.

Weather
Rainfall/precipitation, wind, humidity and atmospheric pressure all
play an essential role in plant growth. Our Smart Agriculture
systems support several advanced weather stations. Weather
stations provide rich data-sets that, when combined with soil
sensors, give you a 360 view of your farming operation. IoT
weather stations can measure the following:
 Precipitation (optical and tipping bucket
measurements).
 Temperature.
 Humidity.
 Air pressure.
 Wind speed.
 Wind direction.

Introduction To Soil Moisture Sensor
 When you hear the term ‘Modern Agriculture’, one of the things that
comes to your mind is a system that measures soil moisture and
irrigates your plants automatically.
 With this type of system, you can water your plants only when
needed and avoid over-watering or under-watering.
 If you want to build such a system then you will definitely need a Soil
Moisture Sensor.

How Soil Moisture Sensor Works ?
The more water in the soil means better conductivity and will result in a lower resistance.
The less water in the soil means poor conductivity and will result in a higher resistance.
The sensor produces an output voltage according to the resistance, which by measuring we
can determine the moisture level.

How Soil Moisture Sensor Works ?
When you run the code , you’ll see the close to the following
readings.
 when the soil was dry (~850)
 when the soil was completely wet (~400)
Then it will stored in Firebase Database.
Users Can Monitor that using our custom Android Application.

Introduction To Rain Drops Sensor
 Raindrop Sensor is a tool used for sensing rain. It consists of two
modules, a rain board that detects the rain and a control module,
which compares the analog value, and converts it to a digital value.
The raindrop sensors can be used in the automobile sector to
control the windshield wipers automatically, in the agriculture
sector to sense rain and it is also used in home automation
systems.

How Rain Drops Sensor Works ?
When the rain board module’s surface is exposed to rainwater, the
surface of the rainboard module will be wet, and it offers minimum
resistance to the supply voltage. Due to this, the minimum voltage will
be appearing at the non-inverting terminal of LM393 Op-Amp. The
comparator compares both inverting and non-inverting terminal
voltages.
 If the condition falls under case(1), the output of the Op-Amp
will be digital LOW.
 If the condition falls under case(2), the output of the Op-Amp
will be digital HIGH. The below diagram shows the equivalent
circuit of both the conditions.
