sensor work with M5stack! pHは興味があるけど、忘れている分野 ① ② ③ ④ I want a good drink. https://tricountywater.com/what-is-alkaline-water-why-should-it-matter-to-mid-michigan-west-michigan-residents/ I forgot about pH. The taste of alcohol is related to pH. pHセンサをM5stackで動か せるようにしよう
and a reference electrode, the voltage (potential difference) between these two electrodes is detected and converted to pH. 横河電機 FLEXA®/EXA PH シリーズプロセス用pH 計(基礎・製品編)TI 12B07A03-012005 https://web-material3.yokogawa.com/TI12B07A03-01.pdf
variability was confirmed using a statistical method called SIX SIGMA feature ・ Converts voltage to pH ・It is insulated because it is affected by the surrounding electrical periodicity. ・ High-performance ADCs are used, so there are no individual differences ※ Features of the pH sensor interface developed
color space and representing it with LEDs. Make it intuitive and easy to understand We will make it possible to represent the color of pH test paper with LEDs.
