The workspace/machine temperature is maintained and monitored continuously using the DHT11 temperature sensor with Raspberry Pi. This developed system triggers the cooling fan ON immediately the temperature is >25.99oC and triggers it OFF immediately the temperature range is
Energy wastage is one of the major challenges that is facing the world now as there is insufficient supply of energy and the little ones supplied was not appropriately used. This energy wastage has made many researchers to engage more on the research to stop this energy waste as a result of inappropriate allocation of energy to some devices even when they don’t need it. This research work was able to design and implement an improved automated DC Motor speed controller system using microcont...
Home security is essential for occupant’s conveniences and protection. This research project designed and implemented a comparatively inexpensive smart surveillance security system that automatically captures an intruder’s image through a raspberry pi camera module and PIR sensor and sends mail to the user via Wi-Fi using the users registered email address. This system operates by triggering the Pi Camera through Raspberry Pi whenever an intruder comes in range using PIR sensor. The Pi ca...
The uncertainty associated with modelling and performance of Electric Vehicle (EV) design could be easily and efficiently reduced by using hybridized renewable energy sources. During the past decade the struggle for effective utilization of EVs was very high due to its unreliability interns of durability and sources of charge. This review classified charge station into renewable, nonrenewable and hybrid based on its sources of power generation. In addition, for this decade there is no extensi...
Fire is a visible effect of the process of combustion as a special type of chemical reaction which occurs when oxygen in the atmosphere reacts with some sort of fuel to bring out flame. This review research extensively detailed the causes, preventive and protective measure to be taken to curb fire outbreak in the society. This showed that the best way to avoid fire outbreak is by adopting preventive and protective measure which includes avoidance of using phone in the kitchen, fueling generat...
This research paper successfully designed, developed and implemented an automated hybrid smart door control system which has the ability to secure a home up to 92% electronically. This smart door system is designed and implemented by building a hardware made up of the Bluetooth module and fingerprint scanner which are interfaced with the Microcontroller system that uses +5V power supply. The written programs were interfaced into the microcontroller chips by plugging the Arduino USB cable into...

A smart grid is an intervention technology for the massive energy demand of the world today. It combines cyber-physical technologies, information communication technology, and electrical power networks from the generating company stations to the end-users while ensuring bidirectional communication among the actors. The smart grid is a complex growing technology that is yet to reach its maturity state. This paper seeks to examine the literature on the state of the art of smart grid technology ...
The uncertainty associated with modelling and performance of solar photovoltaic systems could be easily and efficiently solved by using Maximum power point techniques. During the past decade of 2010 to 2021, the classification of techniques based on intelligent, non- intelligent and their hybrid models are found as potential techniques for detecting the maximum power point of a photovoltaic system. In addition, for this decade there is no extensive and comprehensive review on applicability of...
The recent developments in computational science and smart metering have led to a gradual replacement of the traditional load forecasting methods by artificial intelligent (AI) technology. The smart meters for residential buildings have become available on the market, and since then, various studies on load forecasting have been published. Contingency planning, load shedding, management strategies and commercialization strategies are all influenced by load forecasts. Predicting a lower load t...
A CMOS biosensor with a folded floating-gate is created to detect charged biochemical molecules. It contains a FET, a control-gate and a sensing area. The floating-gate spans the whole device, allowing the sensing area to be placed on top of the FET, resulting in a decrease of the device's total area. The device is sensitive to the polarity and quantity of charged poly amino acids and could be used for electronic recognition of temporal and spatial migration of charges, such as in biological ...
A CMOS biosensor with a folded floating-gate is created for the detection of charged biochemical molecules. It is made up of a field-effect transistor with a floating-gate, a control-gate, and a sensing area. The molecules on the sensing area result in a voltage being induced on the floating-gate and a shift in the threshold characteristics. The floating-gate spans the entire device, which allows for the sensing area to be placed above the FET. This reduces the total device area. The device d...

An open microfluidic system has been developed to dispense and manipulate individual droplets on plastic sheets. Superhydrophobic material is applied to the surface of obtainable plastic sheets by spraying, then hydrophilic symbols are printed with an inkjet printer. The plastic sheets are connected to a two-axis tilting platform driven by stepper motors, which produces mechanical agitation enabling droplet transport. The system has been demonstrated to carry out various droplet operations, s...
