DESCRIPTION OF MODULES
The description of each module used for intelligent agribusiness system is given as follows:

NodeMCU:
IoT platform NodeMCU is free and open source.It initially encompassed hardware based on the ESP-12 segment as well as firm-ware running on ESP8266 Wi-Fi SoC, support for the ESP32 32-bit MCU was later added [13].IoT has become a popular topic in the ecosphere of expertise.It has altered the way of work.More than ever, substantial objects and the digital domain are interconnected.As a result, Espressif Systems, a Shanghai-based semiconductor company, has unveiled the ESP8266, a cute, pocket-sized WiFi empowered microcontroller, at an incredible price.It can monitor and regulator things from everyplace in the world for less than $3, making it ideal for almost any IoT project.

Soil-moisture sensor (SMS) :
SMS is used to assess the soil's moisture content.It measures the amount of moisture or water content that is present in the soil.The water content of the ground or other points is measured by the sensor's fork-shaped probe, which has two exposed electrodes.The water content of the ground or other points is measured by the sensor's fork-shaped probe, which has two uncovered conductors [14,15].SMS uses coefficients to perform the calculations.It makes an estimate of the quantity of water in the soil.It measures the amount of water in the soil and receives and sends analogue signals that are presented alphanumerically.It broadcasts signal's to Arduino for further processing and display that contain information, data, or values related to soil condition.DHT11 Sensor: DHT11 describes the ecosystem's temperature and humidity conditions.It has three pins normally.The first pin is used for signal transmission, the second for indicator acquisition, and the third for data transfer [16].As a result, it can be used for a long time.It provides approximate consequences.It often refers records to Arduino UNO.The information entails the gestures which incorporate the values accrued approximately temperature and humidity.It can be trusted with nature.It responds very quickly.

Relay:
A relay is an electromechanical switch that is controlled by an electric current.The electromagnet is initiated by a low-control signal from a miniature regulator.When the electro-magnet is turned on, an electrical circuit can be either opened or closed.A profoundly, also known as a solenoid, is a weighted iron object that includes an iron armature that can be moved around, at least one set of contacts, and a path with low resistance for attractive motion.The flexible armature is attached to at least one group of the relocating contacts and pivots to the load.When the transfer is de-invigorated, the bodyframe, which is held in place by a spring, breaks the attractive circuit.In this position, one of the two contact arrangements is closed while the other set's remaining components are open.

DC motor:
A pump (motor) is a machine that uses mechanical motion to move fluids.Electrical energy is typically converted into hydraulic energy.The impeller is driven by the DC motor through a straightforward gear drive, which is housed in a plugged case attached to the impeller.The rotor, which powers the impeller and pump, keeps spinning as a result of repeated impacts.Based on how they move fluid, pumps can be divided into three categories: direct lift, displacement, and gravity pumps.Pumps require energy to perform mechanical work to move the fluid because they operate by some mechanism.Pumps come in a variety of sizes and use a variety of energy sources, such as manual labour, electricity, engines, or wind power.They are also used in a variety of applications, from small sale platforms to large scale platforms for effective automation in the smart intelligent based devices.
