temperature in Fahrenheit degrees. We will then convert the analog output voltage of the sensor to an 8-bit digital signal using the Analog to Digital converter ADC0809. Finally we will use 8 LEDs to display an 8-bit binary number representing the temperature. LM34: The LM34 series are precision integrated-circuit temperature sensors. The output voltage is directly proportional to temperature in Fahrenheit degrees. Output voltage increases by 10 mV for every one degree Fahrenheit. For example

Question 7. The highest temperatures within the day are usually recorded at around 2 o clock in the afternoon. Can you explain why this happens? Hot air rises, the land heats up and the air comes up, ground holds heat, heating up through conduction. If you touch a hot sidewalk in the summertime that sidewalk will retain the heat late into the night, the most absorbed heat occurs by 2 P.M after the sun has shone the highest transferring heat. Question 8. Trends since 2004 the overall average temperature

Tardigrades (Water Bears) Tardigrades are microscopic animals, indestructible creatures that can live up to 100 years. There are over 1,000 known species of tardigrades. The water bears mouth can telescope outward that reveal sharp teeth that allowed the water bear to grab on to the food. Tardigrades also can swim, and waters are there natural habitat, and are expected to avoid extinction, because of how tough they are. Tardigrades have podgy faces with folds and wrinkles of flesh, and eight legs

The tungsten filament inside an incandescent light bulb reaches a temperature of 4,664 degrees Fahrenheit when turned on. •Did you know? Unlike many substances, water expands as it freezes. An ice cube takes up about 9% more volume than the water used to make it. •Did you know? The only elements that are liquid at room temperature are bromine and

highlight the many ways we can help save our planet. Our planet is slowly dying right beneath our feet. Our planet has risen 0.6 of a degree for the past ten years. The United Nations panel has predicted that the temperature will rise 3-10 degrees Fahrenheit by the century’s end. Yet we are still burning coal and oil the two of the world’s most top reasons why global warming is happening. If we do not do anything about it what we call as our today we will be saying was our planet yesterday. If global

Essay on Pro Global Warming I believe that Global Warming has been here since we first started using machines, which used steam engines or combustion engines. The first type of wheeling automobile was made in 1769 that is about 250 years ago. So since the first type of ‘car’ was invented so much time ago, then we can assume that there has been carbon dioxide, smoke and steam in the atmosphere. When this happens the atmosphere breaks into little holes, through those holes the rays of the sun pass

liquid, but his thermometer was still inaccurate and didn't use a standardized scale. | 1714 | Daniel Gabriel Fahrenheit | Daniel Fahrenheit was the inventor of the modern day thermometer filled with mercury, and in 1724 he introduced the Fahrenheit scale which could be used to record changes in temperature accurately. On this scale water freezes at 32 degrees and boils at 212 degrees. Fahrenheit based his scale on the human body temperature which was 100 degrees but has been adjusted to being 98.6 degrees
