Capacitive Soil Moisture Sensor For Arduino - (AD69070)

Description:

Finally, your plants can talk to you! Just don't get mad when it's just letting you know when they need something. With this module, you can tell when your plants need watering by the soil moisture in your pot, garden, or patio. The two sensor probes act as variable resistors. Water is conductive, so the more water in the soil, the better the conductivity and the lower the resistance.

Use it in a home automatic irrigation system, connect it to IoT, or simply use it to know when your plant needs some love. Installing this sensor and its PCB will put you on the path to developing a green thumb!

This product measures soil moisture levels using capacitive sensors, rather than resistive sensors like other types of moisture sensors. It's made of a corrosion-resistant material that gives it a long lifespan. Insert it into the soil and impress your friends with the real-time soil moisture data!

The product includes a built-in voltage regulator that provides an operating voltage range of 3.3-5.5V. It is compatible with low-voltage MCUs (3.3V and 5V logic). An ADC converter is required for compatibility with a Raspberry Pi.

Characteristics:

- Interface: 3 wires

- VCC: 3.3V - 5V

- GND: Ground

- AOut: analog output interface
