Beschreibung
Azdelivery soil moisture device has a waterproof probe with high corrosion resistance, which ensures a long service life of at least 6 months in the ground. Soil moisture device with a widened sensor area can improve the electrical conductivity.
Instruction:
- „+“ is the positive power connection, „-“ is the negative connection. Do not connect upside down, otherwise the chip burns through.
- There is an LED stream display on the P mark on the circuit board. It shines when the module works normally.
- Turn the blue potentiometer in or against clockwise to increase or reduce the detection threshold.
- If you turn the potentiometer clockwise so far that the LED display marked with „S“ shines, this means that the test threshold has been exceeded.
Technical details:

Resistant soil moisture sensor
The probe uses an analog resistance to measure the moisture content of the soil. He is a good plant assistant who informs you about whether your plants are thirsty and also used in the automatic irrigation system, in the garden, in the greenhouse, etc.
