YL69 Soil Moisture Sensor

Modulus Moisture Sensor of Resistive Soil Hygrometer, is designed for the control of soil or plant soil moisture. The sensor tips are treated to better resist oxidation and extend its life.

It consists of a probe with two properly separated terminals and a module that contains a very stable LM393 comparator, a power LED and another for digital output activation.

Ideal for producing an automatic irrigation device, so that the plants in your garden do not have people administering them. In addition, it has adjustable sensitivity by means of the potentiometer.

Main features:

• Model: Soil Moisture Sensor (Ground) Resistive
• DC Power Voltage (VDC): 3.3V ~ 5V
• Output voltage: 0V ~ 4.2V
• Current: 35 mA
• A0: Analog output that delivers a voltage proportional to humidity. It can be measured directly from an analog port on a microcontroller, Arduino, among others.
• D0: digital output; This module allows you to adjust when the logic level in this output goes from low to high using the potentiometer
