The psychrometric parameter, Relative Humidity (RH), plays a key role in maintaining the greenhouse environment, where RH must be necessarily within the range of 60% RH to 80% RH. The investigators have presented various processorbased electronic systems as well as embedded systems based on microcontrollers for monitoring and controlling the Relative Humidity (RH) of greenhouse environments. It was also found that precise and reliable embedded systems are in great need. Therefore, an attempt is made to design and develop an advanced microcontroller—the Advanced Virtual Reduced Instruction Set Computer (AVR)—based monitoring and controlling system for relative humidity. AVR's ATmega8 is an 8-bit tiny computer on a chip. It has Reduced Instruction Set Computer (RISC)-Harvard architecture, so it has more promising features—low power consumption, six sleep modes, an inbuilt Analog to Digital Converter (ADC), fast serial communication, a programmable watchdog timer with a separate on-chip oscillator, etc.—than those of other microcontrollers. The RH-dependent data is sensed by the precise temperature-compensated sensor module, SY-HS-220, which is capacitive type and exhibits a current consumption of less than 3 mA. The digital readout is ensured by a smart 16x2 Liquid Crystal Display (LCD) module. The relay circuits are wired to maintain the humidity within the prescribed range by deploying a cooling fan and fogger. The firmware is developed in embedded C using the Code Vision AVR Integrated Development Environment (IDE). This embedded system under investigation is calibrated and standardised to a scientific unit, relative humidity (RH%). The complete development, implementation, and results of the system under investigation are depicted in this paper.
Greenhouse technology is a way to improve crop production. Technology has advanced swiftly in the fields of agriculture and food production and is still paving the way for the optimization and achievement of maximum plant growth. In the current age of Android smartphone applications, a precise mechanism would undoubtedly bring about change. The Internet of Things (IoT) is one of the latest achievements in the field of information and communication technologies, providing global communication and control of sensors, devices, and users with information. This paper proposes a greenhouse monitoring and control system using IoT. The temperature sensor, air quality sensor, soil moisture sensor, Light Dependent Resistors (LDR) sensor, Liquid-Crystal Display (LCD) module, 12-volt Direct Current (DC) fan, electric bulb, water pump motor, and the servo motor with the Internet of Things (IoT) technology make up this greenhouse's monitoring and control system to measure nitrous oxide, temperature, humidity, illumination, CO2, and irrigation to create a plant-friendly atmosphere. The farmers may use the IoT platform to receive the collected environmental parameter data to their smartphones in online mode so they can make the correct decisions without visiting the field.
Renewable energy is a type of energy that may be produced from a variety of resources, including sunlight, wind, tides, geothermal, etc. It delivers sustainable, clean energy that is derived from renewable natural resources. More renewable energy will be used, which will reduce the cost and demand for fossil fuels. The primary uses of solar photovoltaic energy include the production of electricity and heat for a variety of appliances. The development of solar-powered cars was made possible by recent breakthroughs. This study discusses the design and development of a charge controller-based solar charging system for electric automobiles. The suggested system's implementation will lower the price of power and charging and discharging losses. Additionally, one of the suggested solar charging systems is among the steps taken to create a green campus. This paper will show how to create a solar-powered electrical vehicle system and analyzes its performance.
Driver drowsiness and alcohol consumption are the most common causes of traffic accidents and the resulting financial losses. Researchers have been working on developing driver inattention monitoring systems as drowsy and drunken driving have significantly increased the number of road accidents, which results in serious and deadly collisions. The enormous benefits of sleep detection in road transportation cannot be overstated. The proposed work consists of the design of a drowsy and alcohol consumption detection system in the vehicle using an AT Mega microcontroller monitoring and control system to avoid accidents due to driver inattention. This system consists of an eye blink sensor and an alcohol sensor in the vehicle to alert the driver. This proposed system generates a model which can prevent such accidents.
Flying Ad-hoc Networks (FANETs) have been employed in modern warfare for monitoring and reconnaissance to produce a healthy living environment for wildlife through multiple Unmanned Aerial Vehicles (UAVs). FANETs allow multiple UAVs to communicate in 3D space to establish an ad-hoc network. FANETs applications, among others, can deliver costeffective services to help future wildlife. However, adopting FANET's technology in wildlife monitoring is difficult due to its challenges in mobility, data routing, energy, and security considerations. Therefore, this paper aims to look at FANET's possible applications in wildlife Monitoring and the implications and issues that come with them.
