A pH meter is an electronic device used for measuring the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. A colorimeter is a device used in colorimetry. In scientific fields the word generally refers to the device that measures the absorbance of particular wavelengths

ABSTRACT This project is all about to design and fabricate An “Automatic Plant Watering System”.Automated plant watering system is a self-running watering system for plants which are very ideal for small group of gardeners and farmers. The Automatic watering System is mainly developed to run by its own‚ with a minimal supervision of human where it can control the water amount automatically and reduces the work load of an individual. The primary objective of the system is to supply the entire plant

According to Goldenstein (2005)‚ automatic response can be demonstrates b the Stroop effect‚ discovered by John Riddley Stroop‚ an American psychologist who illustrated autonomic processing and conscious visual control by demonstrating the effect of interferences in the reaction time of a task. This demonstrates reading as an automatic processing. As automaticity is the result of learning and repetitive behaviour‚ for those who have had enough practice‚ reading words does not require the use of

How Automatic Transmissions Work by Karim Nice If you have ever driven a car with an automatic transmission‚ then you know that there are two big differences between an automatic transmission and a manual transmission: There is no clutch pedal in an automatic transmission car. There is no gear shift in an automatic transmission car. Once you put the transmission into Drive‚ everything else is automatic! Both the automatic transmission (plus its torque converter) and a manual transmission (with

The automatic fire sprinkler system was one of the earliest sprinkler systems placed into effect. The origin of the modern day automatic sprinkler system dates back to the early 1800’s. The first automatic sprinkler system was created in England in the 1806 by John Carey. It consisted of a pipe with valves held closed by counterweights attached by string. When flames burned through the string the counterweight dropped to the floor‚ which opened the valve that released the water and extinguished the

shocking that worshipers took prayer and integrated it with meter. This common hymn meter allowed even the least artistic of believers to bring a tune to their prayers. However‚ this religiously based meter would not stay exclusively godly. Raised under an ultra-religious father‚ Emily Dickinson used her knowledge of common hymn meter to write secularly. This juxtaposition gave strength to her writings while still limiting her to the strict meter. Even with these restrictions‚ her poems continue to be

The automatic transfer provisions were originally started as a way to become more firm with juveniles to stop in order to lower crimes and hopefully keep them from becoming criminals in the future. It has been very effective in putting juveniles in jail‚ but many argues that it is not doing what the makers of automatic transfer intended it to do. Although automatic transfer is back by many politicians‚ many of the people who oppose it are concerned parents and community leaders. Automatic transfer
