Soil Moisture Sensor Module
This Soil Moisture Sensor Module can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help. Insert this module into the soil and then adjust the on-board potentiometer to adjust the sensitivity. The sensor would output logic HIGH/LOW when the moisture is higher/lower than the threshold set by the potentiometer. With help of this sensor, it will be realizable to make the plant remind you: Hey, I am thirsty now, please give me some water.
Digital output, easy to adjust.
Nickel plating to avoid corrosion.
Working voltage: 3.3V-5V
On-board LM393 chip
Dimension of the board: 3.2cm * 1.4cm
YL-100 Soil Moisture Detection Sensor Module 3pin.
This module is a simple moisture sensor, use measuring moisture and humidity resistance change.
More dry soil, the smaller the output voltage. The more humid the output voltage increases.
The module will be inserted into the soil through the AD converter voltage signal can be detected in soil moisture.
With FOR Arduino, small pumps and other modules automatic watering system
Module size: 60 * 20mm
Operating voltage :3.3-5V
Output voltage: 5V power supply, about 0-3.7V (3.7V voltage is fully immersed in water)
The output voltage is for reference only, because of the different water quality factors, please actual measurements.
This module is a consumable item, will be affected by environmental corrosion, life is about 12 months.
