3Pin Soil Hygrometer Detection Module Moisture Sensor Analog Output

Specification: 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 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 Package Included:1 x Soil Hygrometer Detection Module
