If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller ... is linked to the 5V line of the Arduino. GND of the module is the ...

when the sensor is not submerged or is in clear water (and a bit lower than that in analog mode). Here’s one simple Arduino code for a quick test (connect sensor module’s output to analog pin 1 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. As soon as the ...

Arsenic contamination in water is a serious health ... in remote areas can benefit from it. By connecting the sensor to a circuit board and an Arduino module for real-time data transmission ...
