Overview:

  • Sensor for water turbidity
  • Output of the turbidity as an analog value
  • the module must be calibrated with an appropriate solution before use
  • Protect the sensor module from light

Technical data

  • Voltage: 5V DC
  • Measuring range: 0-1000 NTU
  • Operating current: 40 mA (MAX)
  • Response time: < 500 ms
  • Insulation resistance: >100 MΩ
  • Analog output: 0-4.5 V
  • Digital output: High/low level signal (threshold value can be adjusted by setting the potentiometer)
  • Operating temperature: 5 ~ 90 °C
  • Cable length: approx. 39.5 cm

Precautions for use:

  • The sensor must be calibrated before use.
  • The sensor must not be completely immersed in water. Only the vent opening at the small, round end of the head must be immersed in water for measurement. The large head above it must not be wiped off.
  • The sensor is realized by using the refractive index, so that the light also interferes with the sensor. Therefore, it should be kept away from light interference when in use.
  • The voltage must not exceed 5 V.

Produkt ok, Datenblatt und Beschreibung der Inbetriebnahme ungenügend

Nach 4 Stunden Arbeit und Hilfe unserer technischen Abteilung habe ich es endlich geschafft, den Sensor in Betrieb zu nehmen. Wenn er dann klappt, scheint er gut zu funktionieren. Was ich gerne bemängeln würde:
1. Es ist kein Datenblatt hier bei Funduino mit angegeben, auf dem man nachgucken könnte, wie genau der Sensor funktioniert. Das hätte sehr geholfen. Dort hätte auch wahrscheinlich die Lösung zu dem zweiten Problem gestanden:
2. Der Sensor gab zuerst nur zufällige Ergebnisse aus. Das lag daran, dass vor Inbetriebnahme noch zwei Lötstellen miteinander verbunden werden müssen. Je nachdem welche, von insgesamt 3, Lötstellen man verbindet, erhält man dann einen digitalen oder einen analogen Ausgang der Messwerte. Dies wird leider auch nicht in dem angegebenen "Anleitungsvideo" beschrieben. Hier hilft lediglich ein Blick in die Kommentare. Dieses Problem wird dann durch den Kommentar von @cauesomenzi wie folgt gelöst: "There are three exposed pads close to the output pin (middle pad). You need to solder a jumper across two of them. Refer to the 1-minute and 22-second mark in this video to view the soldered pins. This resolved the ramdon values issue. Good luck."

3. Der dritte und letzte Punkt betrifft das Anleitungsvideo an sich. Hier wird gesagt, man könne anstelle des Arduinos auch einfach einen ESP32 verwenden. Wenn man den Sensor aber mit 5V betreibt, und dieser ein Signal über 3,3V ausgibt, kann dies zu Schäden beim ESP32 führen. Bedauerlicherweise wird dies im Erklärvideo nicht erwähnt, sondern lediglich wieder in den Kommentaren von @rollyavecilla mit dem Kommentar: "ESP32 has 3.3 voltage level ADC and you are using an algorithm for an ADC with a voltage level of 5 volts. That is very huge difference and ESP32 will not have the same reading not to mention the possibility of destroying the ADC pin." gelöst.

Insgesamt lässt sich sagen, dass das Produkt ok ist. Funduino sollte aber ein Datenblatt anfügen, sowie eine deutliche bessere Anleitung der Inbetriebnahme. Ohne Hilfe von Fachleuten würde eine Person, die ein "Plug an Play" erwartet die Probleme nicht lösen können.
