Second i would like to express my deepest gratitude to my family and friends for their Cooperation and supported me from the start in making this project by giving their valuable comments and corrections, and their day to day encouraging ,support and guidance in carrying out the project. Lastly I would like to say thanks to all of our TVET staff members for their actively participation, for the completion of this project and their good behavior and attitude. i Wesenu Abitew Page 3 Water level indicator 2023 1. Rationale A water level indicator is an electronic circuit which indicates the various levels of water inside a tank. This happens when rising or dropping water levels come in contact with the respective water sensors arranged step wise inside the water tank at different depths. I describe the best and interesting way to make simple water level indicator circuit using transistors, buzzer and some LEDs. 2. Objective :-Reduce water wastages, and unplanned downtime of waiting for water Specific objective To increase income of Small Micro Enterprise those produce and sell this product To diminish the time expense To help Small Micro Enterprise those working on electronics maintenance To introduce project based training by integrating Four (4) packages. To maximize raw materials utilization and application of KAIZEN To produce quality, marketable and saleable technology project The decisive factors for selection of this project proposal are: Wesenu Abitew Page 4 Water level indicator 2023 Marketability: Provision of acceptable returns of rewards for the risk and effort required; water wastages in our country Real Demand/need: Responds to unsatisfied needs or requirements of customers who have the ability to purchase and who are willing to buy; unplanned downtime waiting for water Be competitive: Be equal to or better (from the viewpoint of the customer than other available products or services Meet objective/profitability: Meet the goals and aspirations of the person or organization taking the risk; Accessibility of resources or raw materials and skills of implementer; Ease to implement; Consideration of financial ability; Best business location; Identification of target group – that is, who are customers; for what purpose they buy the product/services; here, when and how they need; Competition/creativity and adaptation of changes; Risk assessments and evaluation; Using technology to increase productivity and better resource utilization; Seeking information from different corners, which is about the market. New technology, government policy in relation to tax as well as different issues; suppliers, and other factors that contribute to the work; Wesenu Abitew Page 5 Water level indicator 2023 3. Project Description In this electronics project, I have explained how to make a simple Water Level Indicator using the BC547 transistor. A buzzer is also connected with the water tank level indicator circuit, so when the water level reaches maximum level the buzzer with starts along with indicator LEDs. Water level indicator This technology is important for controlling the wastage of water, especially for a people of our country. When the water level is too high or too low or exceeds the higher limit, it can detect the water level easily by hearing an alarm sound or from different colors of a light bulb. We can also measure the fuel level in motor vehicles and the liquid level containers which are huge in the companies or home. 3.1 Project Explanation: The basic idea of a water level indicator is to indicate whether water is available or not in the water tank. Project enables to check water full or not. Operation Instruction: Connect to 9V supply battery for the device. Put ON the switch. Connect the cables in the water tanker. If water is on 25, 50, 75 or 100 device to indicate the light, on all conditions 3.2 Assembled diagram of water level indicator Wesenu Abitew Page 6 Water level indicator 2023 .
