- 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
- 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.
