    In Nigeria, plantain chips are in high demand and this demand is not being met by most small scale food industries and shops due to some critical factors. Shops are only able to fulfill approximately two-thirds of the demand. The biggest obstacle towards attaining self-sufficiency in the production of plantain chips is the intensity of labor involved and the tediousness of the process which often culminate into prolonged production time. Plantain has a large amount of sap and this causes the skin to adhere to the fruit inside. After peeling, they must be sliced into discs to fry into chips. Worker will hold up to eight plantains in one hand and rapidly slice them using a wooden mandolin. Because of the rapid pace at which they slice plantain and the absence ofhand gloves on the workers, accidents are very often unavoidable. These presents health hazards to both the worker, who may develop infections from their injuries, and customers who may consume an unsanitary product. This development is very uncomfortable and tasking on the workers. They must hold the mandolin over the fryer so the plantains will fall in, which causes splashing of the boiling hot oil that occasionally hits and injures the worker. This research focused on design and fabrication of motorized / power operated plantain slicer to meet the raising demands for plantain chips in Nigeria. The objectives of this research was met as the machine has the capacity to produce plantain chips of uniform size in shorter time and a greater slicing efficiency of up to 96.84% while keeping the cost of themachine at an affordable price

    The implementation of a Microcontroller based automatic door control with visitor counter will lead to vast improvement on electronic security designs. Nevertheless, for a system with large volume of movement with little or no security consciousness, a door system to fit the system without unnecessary delay in the free flow of movement usually tends to pose a problem. Usually, in this kind of scenario, an automatic door system with a means of detecting incoming traffic so as to open the door as required, thus the design and operational principles of a microcontroller based automatic door with visitor counter. The design is made of sensors that detect human presence, a dynamic display unit that displays different messages at specific time, the H-bridge driver IC controls the movement of the motor attached to the door. The whole system is controlled by an 8051microcontroller (89s51). Keywords: Microcontroller, H-bridge driver IC, Sensor, Program, Remote

    Design And Implementaion Of A Microcontroller Based Home Automation System Using Aiwa Remote

    The need for a remote control system that can control domestic appliances and various lighting points and sockets has often been a concern for users. At times users find it inconvenient and time consuming to go around turning their appliances on or off each time there is power outage or each time they are leaving the house for work. It has also often led to damage of appliances due to the fact that an appliance was not turned off before leaving the house. The Objective of putting up this project, therefore, is to design equipment that can facilitate a convenient and easy way of controlling our domestic appliances, lighting points and sockets especially in powering them, without always going to appliances physically by ourselves. This objective will be accomplished using various components which include a Microcontroller (AT89C51) which acts as the backbone of the project together with other components

    This dataset contains cellular and geo-spatial information of a 10 km distance along Akure-Ilsha road in Ondo state, Nigeria. The data was acquired using a designed data acquisition system which was kept inside golf3 vehicle interfaced with Acer laptop, the data was acquired as the vehicle moves from the reference point (7.39919, 5.05944 ) to its destination point (7.32818, 5.10836), it harvests GSM signal Strengths from a base station in intervals with its time, latitude and longitude simultaneously as the vehicle moves along the travelled rout; the data acquired shows the variation of signal strength against distance along the road from one base station to another in the travelled path.

    The rapid increase in the occurrence of road accidents in Nigeria requires the deployment of real time techniques that is equipped to reduce one of the critical factor that have been identified by the Federal Road Safety cooperation of Nigeria (FRSC) that constitute the major cause of road accidents which is over speeding. This was achieved through the design and implementation of real time vehicle speed monitoring system using cellular signal along the travelled path. A data acquisition device was developed to capture in real time the signal strength and geospatial data (longitude and latitude) along the travel path which is used in determining the speed of the moving vehicle. The acquired data was correlated with data obtained from standardize equipment to establish the integrity of the data, the data was then used to develop the algorithm by obtaining equation for the path-loss gain in terms of signal strength against distance. Equation for the base stations covering a distance of 10km were obtained for analysis. Consequently from the equation, the distance from two locations along the route can be determined from corresponding signal strength values, the average speed results for the drive test, new Model and using Latitude and Longitude are compared as followed 88.05km/hr, 75.67km/hr and 88.2km/hr respectively. With this a new paradigm shift in vehicular speed management is developed based on Cellular signals for real time vehicular speed determination.

    QUANTIFYING CASSAVA WASTE GENERATION AND BIOGAS PRODUCTION IN EHA-ALUMONA GRINDING MILLS

    Garri processing is a major agricultural and food related activity which leads to waste generation and this waste in turn constitute environmental problems in terms of stench smells and poor hygienic conditions that allow microbes and germs to thrive. Rural dwellers are normally poor thus the payment of electricity bills impoverishes them further. Inadequate energy supply and environmental pollution are gargantuan problems confronting Nigeria and many other developing nations of the world. In this research we estimated the cassava waste generation rate associated with processing of cassava for garri production activities and estimation of amount of biogas generation from specific mass of the waste. A simple digester is fabricated for sample digestion process. The result was then used in estimation of biogas generation potential of the garri processing mills. Five different garri processing activities were studied for statistical reliability of results. The results of the five studied garri production activities as described in the methodology were summarized in table 3.1. The quantities ��, ��, �� and ��� were directly measured as described while the ��� and ��� were calculated in each cell of table 3.1 as differences���= ��− �� and ���= ��−��. The sum of waste generated in each of the studied activity � is given in equation (3.1). The counted number of bags for each studied activity was given as. The estimation for daily generation of pressed bags of cassava by the community is ,�����= 44.35 bags.Keywords: Biogas, Energy, Cassava, Waste, Garri

    Just like other solar cookers, the solar box cooker needs energy gotten from the sun to operate without producing emissions. In this research, a solar box is fabricated to reduce over-dependence on fossil fuel for energy generation. This reduces the environmental degradation caused by the use of other sources of energy. The ASHRAE empirical model was used to obtain the solar irradiance present in Omu-Aran metropolis. Thereafter, the no-load and load test was conducted to determine the cooker’s thermal performance. The tests were conducted between January 2018 and January 2019 in Landmark University, Omu-Aran, Kwara State, Nigeria with geographical coordinates 8° 8' 0" North, 5° 6' 0" East. The average energy and exergy efficiency of the cooker were 32oC and 28oC respectively. A decrease in the efficiency of the cooker was observed. This was because the reflector, which is made from aluminium foil, was degrading. As a result of this degradation caused the sun rays (radiation) to be reflected poorly into the absorber and also caused a myth of overcast sky. Meanwhile, the variation in solar radiation during the sensible heating test resulted in the fluctuation inefficiency. The ratio of water to absorber temperature which was above 0.80 during the pre-boiling heating process indicates that the cooker can be recommended for sterilization
