Keyestudio RJ11 EASY plug Soil humidity Sensor Module for Arduino STEAM

SKU: KS0108

• RJ11 EASY plug soil humidity sensor module for Arduino STEAM; can read the amount of moisture present in the soil surrounding it
• Ideal for monitoring an urban garden, or your pet plant water level
• Uses two probes to pass current through the soil, then reads that resistance to get the moisture level
• More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance)
• Use this sensor to make an automatic watering device, helpful to remind you to water indoor plants or monitor soil moisture in garden; should be used together with EASY plug control board; connector Easy plug, power supply 3.3V or 5V, working current ≤20mA, output voltage 0-2.3V, sensor type Analog output, surface finish immersion tin
