Resistive Soil Moisture Sensor,humidity Detector,with Probe,pack Of 2

RESISTIVE SENSOR - The probe uses analog resistance to detect the moisture content of the soil. It is a good plant helper to make you know if your plants are thirsty and it can also be used in the automatic watering system, garden, greenhouse, etc.DIGITAL VALUE OUTPUT - This soil moisture detector outputs a low level from the DO port when the detecting humidity reaches the threshold value. Good to work with for Arduino/Raspberry Pi.ANALOG VALUE OUTPUT - The AO port on the soil humidity sensor outputs analog value(voltage), and you can acquire the real-time data via the AD port of your single-chip microcomputer(MCU).ADJUSTABLE THRESHOLD - Clockwise/counter-clockwise rotate the blue potentiometer to increase/reduce the detection threshold. On-board power and signal indicator make you know the working status of the board at a glance at any time.CORROSION-RESISTANT PROBE - A waterproof sensor probe with high corrosion resistance ensures a long lifetime at least 6 months in the soil.colour:BlackMaterial:Composite materialsize:3 x 1.5cmPackage Contents:2 x PROBE2 x ModuleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
