Soil Moisture Sensor With Watering Warning
We are creating a device that measures soil moisture, based on a WEMOS D1 mini and a Capacitive Soil Moisture sensor.
With cloud integration the measurement of the sensor sent to the IoT Guru Cloud, where we get fancy graphs and we can set a warning that we need to watering the plant.
WEMOS D1 mini
Capacitive Soil Moisture sensor
Step 1: Connection of the Hardware
The Capacivite Soil Moisture sensor has three pin:
3. Analog output
You can connect this pins to the WEMOS D1 mini in same order:
Step 2: Arduino Source Code
The source code is contains an IoT Guru Cloud integration, you can check out our
about the integration. You will need:
The code will send an analog measurement in every one minute.

Step 3: Check the Graph in Your Account
If your device can connect and can send data, you will be see something like this:
Step 4: Watering Warning
You can set range alert and the
IoT Guru Cloud
will be alert you whenever the measurement is less than the minimum or greater than the maximum.
