Here’s a turbidity sensor driver circuit based on LM393 for the intended task. Tweak it! On the Other Side. While I was experimenting with my old TSD-10 turbidity sensor lifted from a defunct washing ...

Then, submerge the turbidity sensor in fresh water and make sure the green indicator lights up. Next, submerge the sensor in dirty water and see if the red indicator lights up or not. ... (AN_OP) ...

A turbidity sensor measures how much silt is in the water; the other sensors measure Ph, dissolved oxygen, and temperature. The sensor pod is suspended inside a double ring of PVC for maximum ...

It also has a GSM/3G modem, allowing it to report the measured water quality to a central database. All of this is housed in a 3D-printed enclosure that makes the whole setup easy to carry and ...

When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant.
