1. Introduction of IOT :-

         

       IOT (Internet of thing) it is a system of interrelated computing devices, mechanical and digital machine provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

       IOT is used to connect the devices to the internet with the help of some module like WiFi module such as we are using the ESP32 module in this monitoring system is transfer the data into cloud and fetch the data.it also control the devices by using internet the devices are always connected to the internet means the device are in online state so when the device is online we can control it manually with the help of Internet access. IOT  sector is increasing day by day the net worth of IOT industry in global market is 212 billion U.S dollar the forecast suggest that it will grow around 1.6 trillion by 2025

2. Introduction to solar power generation : 

                                            

         Solar power is the conversion of energy from sunlight into electrical energy by photovoltaic effect this is a renewable energy source of electrical energy. This solar panel or solar cell is made up of  crystalline silicon. It is a form of photoelectric cell,defined as a device whose characteristics,such as current ,voltage and resistance. Solar power generation is growing widely across the world. every one is adopting renewable energy sources so that the environmental get more better and the pollution level get decreases .In India the Total solar power generation is 38  GW so the government is investing lot of money in solar power sector. The global solar energy market was valued at 52 billion U.S dollar in 2018 and is projected to reach 223.3 billion U.S dollar by 2025.

3.  Working of solar monitoring system :-

1.     The solar panel voltage and current is monitored with the help of sensor like current sensor and voltage sensor . This current sensor gives the value of current flowing through the solar panel and the voltage sensor give the value of voltage appear across its solar panel .

2.     This both the sensor data is given to the ESP32 module which is combination of controller and WiFi module. This module is program with the help of Arduino IDE software.

3      This module receives the data from both the sensor and analyse it and send it to cloud/database. The cloud will be Firebase which is free data base .

4.     This data is saved in the server of Firebase and we can display the data in any mobile/laptop application

5.     we need an IOT platform which design such that allow the user to connect , visualize and analyze their sensor data over the cloud. Let suppose we want to monitor the voltage and current of a solar panel and store the values somewhere in the cloud so that they can be elaborated later.This is a typical scenario where it is necessary to know how to send data from the ESP32 to the Cloudor IOT platform. 

   

6. API it is an application programming interface  is a computing interface which defines interactions between multiple software intermediaries. It defines the kind of calls or request that can be made. An API specifies how software components should interact. 

7. Get your API key and set a simplify the data exchange process between your device and the IOT cloud.  Now install ESP32 module in your arduino IDE 

• Component specification 

1. Current sensor module:-

figure show the current Sensor module ACS17 with a range of 30A it consist of a precise ,low offset linear hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field in which the Hall IC converts into a proportional voltage.this sensor cost is  145 rupees

2. Voltage Sensor module 

        Voltage Detection Sensor module is a Simple and very useful potential divider to reduce any input voltage by a factor of 5 . this allow us to use the Analog input pin of a micro controller to monitor Voltage higher than it capable of Sensing. This sensor cost up-to  99 rupees  in India .

3. ESP32 Module:-

        

         ESP32 module is a series of low cost ,low power system on a chip microcontrollers with integrated wifi and dual mode  Bluetooth. The ESP32 module series employ a Tensilica Xtensa LX6 microprocessor in both dual core and single-core variations and includes built in antenna switch, RF balun, power amplifier, low noise receive amplifier, filter, and power management module .

        FEATURES of the ESP32 include the following

Processors:-

         CPU: Xtensa dual-core 32-bit LX6 microprocessor, operating at 160 or 240 MHz and performing at up to 600 DMIPS 

        ultra low power (ULP) co-processor

        Memory: 520 KB SRAM

        wireless connectivity:

•        WiFi: 802. 11 b/g/n
•        Bluetooth

       Cloud Computing:-

                             Cloud computing is the delivery of on demand computing services from application to storage and processing power typically over the internet and on a pay-as-you-go basis.

How does cloud computing work ?

Rather than owning their own computing infrastructure or data centers , companies can rent access to anything from applications to storage from a cloud service provider.

one benefit of usind cloud computing services is that firm can avoid the upfront cost and complexity of owning and maintaining their own IT infrastructure and instead simply pay for what they use when they use it.
