An "about me" speech is a short, personal introduction that allows you to share information about yourself with your audience. It can be used in a variety of contexts, such as at a job interview, during a presentation, or as a way to introduce yourself to a group of new people.

There are a few key elements to include in an "about me" speech. First, you should start by introducing yourself and giving your name. You can also provide a brief overview of your background, including where you grew up, your education, and any notable achievements or experiences.

Next, it's important to highlight your interests and hobbies. This can help to give your audience a sense of who you are as a person and what you enjoy doing in your free time. It's also a good idea to mention any skills or expertise you have, as this can help to show your audience what you are capable of and how you might be able to contribute to a group or project.

Finally, you should conclude your "about me" speech by sharing your goals and aspirations. This can be a great way to motivate and inspire your audience, as well as to give them a sense of what you are working towards.

Here's an example of an "about me" speech:

Hi, my name is [Name] and I'm from [City/State]. I grew up in a small town and always had a love for learning. I received my bachelor's degree in [Field of Study] from [University] and have since worked in a variety of roles related to my field of study. In my free time, I enjoy hiking, reading, and playing the piano. I'm also an avid fan of science fiction and fantasy novels.

One of my biggest passions is using my skills and expertise to make a positive impact in the world. I believe that education is the key to unlocking our full potential and I'm always looking for new ways to contribute to my community. My goal is to eventually become a teacher and inspire the next generation of leaders and innovators.

Simple Water Level Indicator with Alarm (3 Tested Circuits)

Hi Ian, that may not be possible without some elaborate modifications, I have updated the modified design for enabling this operation, you can find the upgraded design at the bottom section of the article. I hope my explanation of my requirements makes sense to you, but one thing is for sure, i know now how to switch what ever at what ever level with this circuit. I want to use the water level circuit to indicate the water level in my reservoir without opening the reservoir and to protected my pump and heater from running dry or switch off power to pump and heater below sensor D for example. Short lengths of four 18 SWG copper wires may be used for sensor probes. I hot glued it as it would keep the wires firmly fixed to the female connector,and there won't be any dis-connection. First let us build a water level alarm using simple transistors. As i have shown in the diagram the signals are drawn in the Green color.

The heater stays on permanently and regulate the water temperature with a thermostat, the pump is controlled through a timer at regular intervals of two hours off and fifteen minutes on. Thanks, Vespucci Hello Swagatam and thank you for this blogpost. Pls view Hi chadrashekhar, you should always check the circuit without a load, and once finalized then you can attach a real load. Use of just one IC makes the entire configuration very easy to build, install and maintain. Each channel is good for 500 mA. The controller is now installed and works reliably as intended.

I have 9 Volt and 12 volt transformers. All these 6 probes wires are fixed around 15mm plastic conduit with thin plastic rope. For avoiding this problem, additional motor starter must be used, so that relay's function is limited to control the motor starter only, and pump never heats up. That end's this part of connecting the cable with the circuit and the next part will be learning to make the sensors for the water tank. I want to combine my existing water lever controller with new indicator circuit. If you see voltage there that means no current so buzzer is off. .

Then as when the nut is fitted to the casing, don't bolt the nut as such. In my part what i did was make it with wire casing, that are utilized while wiring at houses, but if in case you don't have you can make it with a PVC pipe. It means when the water reaches t the top of the tank and bridges the negative supply to this input, the gate output becomes positive and riggers the transistor T1, which in turn switches the power to the motor pump through the wired relay contacts. After the filtering the voltage is then directly fed to the voltage regulator 7805 with a filtering capacitor. This is often needed because the conductivity of water changes slightly from place to place. It is a monolithic IC consists of seven NPN Darlington transistor pair.

For testing just put the power on and you will see some of the LED's glowing, indicating the level of the tank, if you see only one of the RED glowing then your tank is fully empty and it is time you should turn on your water pump. When the interrupt passes, it will revert back to its initial state, which is LOW in this example. Even though the LED is glowing I doubt how many more days will this connectivity go on. You will notice that there were two pins extra, so i made this two pins connect together and made a common point for the sensor going to the tank. The DC output was connected to the LED.

Now for installation of the device you should find a suitable place for easy view of the LED lights. Congratulations again, for your work! You can implement these home science projects for high school students. This tends to heat the pump because off in-sufficient current flow to pump observed, new pumps works fine. The actual implementation was that I have dipped the output from the step-down transformer 6-0-6 which is an AC current into the water through the aluminium wires. From the regulator IC the output voltage is then again filtered with a capacitor and is fed to the circuit. Thus finishes the installation of the device and test it by turning the device on and checking the water level in the tank.

The mid must be considered for future expansions. Do you have any suggestions on how to solve this? Simply use 2mm 316 stainless welding rod forced through a 1. You can manually touch the positive to the respective inputs of the IC to simulate water filling and check the response of the circuit. When water in the tank just touches the highest level detector strip L12, the DC voltage is developed across capacitor C2. Can you help me telling me how to deal with the circuit running reversing the relay? And below three transistors are connected to three different LEDs like Red, Yellow, and Green LED through resistors R. The very low indication led turn off the Low indication led turn on nothing else 4 Probe D - if the water touch probe The low indicator turn off.

[Project] Water Tank Level Indicator and Alarm System

This turn ON the white LED and the buzzer connected to the transistor Q3. This reverts the output of N1 at zero, which does not impact the IC 4017 output, and the motor keeps running and emptying the tank, until finally the water goes below the lower probe. My rented house that i live is about 3 stories high and i needed approximately 15 meters of CAT5 Cable. As per this circuit it is working very well, but when it is connected to Half or One HP motor, when it goes beyond 'B' motor getting ON and when it touch 'A' motor is getting OFF, and then now it is in standby for 1 hour and 30 minis motor is in OFF condition only, but same all three points A,B,C are immersed, after 1 hour and 30 minis motor is switched ON automatically if it is even all three are immersed and it is not getting switched off till we OFF manually, can you please help how to rectifies this issue. The distance and fluid between probe 6 and the common probe wire should be less than 900k ohms and any fluid under this resistance will trigger the circuit.

This output is given to the buzzer. We can see how the LEDs light up sequentially in response to the increasing water level coming in contact with the respective sensor points inside the water tank Part List. There are total 7 transistors in the circuit and each one will be sensing the level of water present in the overhead water tank. Applications: Water harvesting is one of the most important tasks. Therefore when you switch on your unit if you see only one Red LED lighting up then you know that the is no water present in the tank and therefore you should make you water pump on. Mohamed Said Instead of buzzer place resistor typically 100kOhm would do it higher if that npn allows it.

Any assistance you can render would be much acknowledged. The probes and associated wiring to the surface area had been in place at those ranges. This simple DIY project can be the best solution for this problem. I am having small doubt about Resistance. Now put the loops of wire to the nuts that you have snuggled to the plastic wire biting and make the wires come out from every nut that you have built. Also when the water touched the PIN 1 of IC the relay stopped but the voltage across relay is 6-7Volt.
