If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

To help monitor that environment he built this sensor array ... pushed into the soil and a resistance reading indicates moisture level. By driving voltage on one screw, and measuring voltage ...

In a way, the magic of a soil moisture sensor’s functionality ... how much water is around them. By measuring this effect on a probe sunk into dirt, the sensor can therefore indirectly measure ...

The small soil meter has two probes — to read moisture and pH levels — and a sensor at the top to measure light intensity. The display doesn't provide ultra-accurate readings, but it's enough ...

Soil moisture sensors can help farmers save water, by letting them know when their crops actually need to be watered. An experimental new sensor could be particularly helpful, as it incorporates a ...
