The MonkMakes Sensor Board for micro:bit can be used to measure sound levels, temperature and light levels. Very Good Tuto !!! A pH meter takes advantage of this and works like a voltmeter: it measures the voltage (electrical potential) produced by the solution whose acidity we’re interested in, compares it with the voltage of a known solution, and uses the difference in voltage (the “potential difference”) between them to deduce the difference in pH…. Three values from the accelerometer and three from the gyroscope. Bromine can be used as a disinfectant alternative for chlorine, especially in spas and hot tubs. We checked the pH values of three different liquids and got accurate values.

Roughness and pH changes of enamel surface induced by soft drinks in vitro-applications of stylus profilometry, focus variation 3D scanning microscopy and micro pH sensor. It can accurately be quantified by a sensor that measures the potential difference between two electrodes: a reference electrode (silver / silver chloride) and a glass electrode that is sensitive to hydrogen ion. PH is a measure of acidity or alkalinity of a solution, the pH scale ranges from 0 to 14. It has an LED which works as the Power Indicator, a pH sensor, a BNC connector, a variable resistor which is used for the calibration which I will explain during the testing and PH2.0 sensor interface circuit. The sensor is linear so by taking two points we can deduce the equation to convert the measured voltage to pH. Sensor Size. This website uses cookies to improve your experience.
