Productdetails

  • TDS probe sensor for arduino is used to measure TDS value of the water. The TDS value can be used as one of the basis for reflecting the cleanliness of water.
  • TDS (Total Dissolved Solids): indicates how many milligrams of soluble solids dissolved in one liter of water. The higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is.
  • TDS Meter Probe is plug and play and easy to use. Also, the wide supply voltage of 3.3~5.5V and the analog signal output of 0~2.3V. Comes with XH2.54-2P/3P connector wires
  • Its Electrode can measure conductive materials, such as suspended solids, heavy metals and conductive ions in water. Also, it can be used for water quality testing in the field of domestic water and hydroponics
  • With this sensor, you can easily DIY a TDS detector, and easily check the cleanliness of the water to make your water quality better. How to use: Search for "keyestudio wiki KS0429" in Google Chrome to get the wiki online tutorial for this product.

KEYESTUDIOのサイトにあるプログラムを見て、Raspbery PI PicoのMicropythonに書き換えてみた。とりあえず、値は示しているようだ。水道水を測定すると60ppmくらいで、伊右衛門を測定すると220ppmくらいを示している。正しいのかどうかは分からんが、一応日本の水道水は100ppm目標らしいので合ってるのかも?一応、DS18B20も購入し温度補正は行っている。(こちらは棒温度計と比較し正確性は検証済み)校正液買わなきゃなと思いつつふと思い出した、10年くらい前にアピストやってた頃にマーフィードのTDSメータ(すでに壊れて比較には使えん)買った際に校正液も買ったことに。冷蔵庫の野菜庫に隠したのを掘り出して計測してみた。これは、瓶には、650ppmと書いて有るが、実際計測すると350ppm程度にしかならない。これは可能性として以下の事が考えられる。・式間違っとる・校正液が古すぎてまともな値を示していない・センサが壊れている。つう訳で今度ショップでまっとうな校正液買って来てから追試験することにしよう。Amazonで探してみたが、マーフィードのはAmazon発送のがないので送料の方が高い(流石に6~700円の代物に/~800円の送料払う気にならんわ。)か、無駄に高い校正液しかないので。^^;

Uso la sonda con un wemos d1 mini per controllare il mio depuratore a osmosi inversa va benissimo si adatta tranquillamente a tubi da 1/4 di pollice soddisfatto del prodotto

Misura la conducibilita di un liquido, in genere si usa per l'acqua, per avere una idea della quantita di sali in essa disciolti, nello specifico lo uso per gli acquari.Al momento pare che la misurazione sia abbastanza ripetitiva.L'unica nota negativa e' la lunghezza del cavo della sonda di circa 50 cm, che avrei preferito piu lunga anche perche la sonda non e' facilmente autocostruibile, mi tocchera' allungarne il cavo ad entrambe, ma certo, accorciare e' un lavoro che sicuramente esce piu' pulito e meno problematico per affidabilita nel tempo di allungare, per questo 4 stelle.

heck it works, but if you want accuracy with your projects the nature of a 0-2.6v analog value is a bit silly when measuring TDS via water conductivity, especially when compensation code fills more than 50% of your program area, would have been better if it was an SPI or similar serial stream that can be queried at a whim to get a fixed number of 0-1023(10 bit number that fits the 0-9999 TDS measurement range)they are cool and the amber power light isn't stupid like some green and blue LED's being run at the same current as red ones so you literally have to snap it off to not be blinded when you leave a setup running at night
