SENSORS IN AGRICULTURE 

            Sensors in agriculture and forestry play an important role today. Now a days , smart agriculture is increasing in this world. This can be very useful to the farmers and also to get more cultivation in crops, proper maintenance ,etc,.Here, we are going to see some basic sensors that are using in the agriculture field.

pH SENSORS:

             The nutrients that we get from the plant growth is more essential for human and to the animals . By using pH sensors we get a deep knowledge about our soil conditions, how the nutrient consistency in our soil or the presence of any unwanted chemicals . These sensors are very helpful in smart agriculture to monitor daily or weekly or annually fluctuations in soil pH and nutrient values.

TEMPERATURE SENSOR:

             In two ways, this sensor play a great role in smart agriculture, ambient condition monitoring and mechanical asset monitoring.

             Highly accurate temperature and humidity sensors, preceise predictive temperature forecasts are imperactive to the ice wine industry.

LOCATION SENSORS:

              These sensors determine latitude,longitude and attitude of any position within required area. They take help of GPS satellites for this purpose.

OPTICAL SENSORS:

               This sensor is used to measure the properties of the soil. These sensors are installed on drones, satellites or robots to determine clay, organic matter and moisture contents of the soil .

GAS SENSORS:

              Gas sensors are important in agriculture  field for many number of applications.Commercial greenhouse control systems measure and temperature control and carbon dioxide concentration for optimal crop growth. The co2 guardian NG is designed for long term continuous measurement of co2.

               The Gascard NG sensor is widely used in pig and foultry processing applications to detect the co2  level where high concentrations of co2  are used.

                Spoilage of stored grains can be detected with gas sensor for co2 measurement .For monitoring methane emissions from agriculture and Dairy farming.

MECHANICAL SENSORS:

                It measures soil compaction or 'Mechanical Resistance'. The sensors use a probe that penetrates the soil and records resistive  forces through use of load cells or strain gauges.This similar technology is used on large tractors to predict pulling requirements for ground engaging equipment.

DIELECTRIC SOIL MOISTURE SENSORS:

                It access moisture levels by measuring the dielectric constant (an electrical property that changes depending on the amount of moisture present)in the soil.

AIRFLOW SENSORS:

               It measures soil air permeability. Measurements can be made at singular locations or dynamically while in motion. The desired output is the pressure required to push a predetermined amount of air into the ground at a prescribed depth. Various types of soil properties,including compaction, structure , soil type and moisture level, procedure unique identifying signatures.
