This YL-100 Soil Hygrometer Detection Module Soil Humidity Moisture Sensor 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
