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.
Supplies:
WEMOS D1 mini
Capacitive Soil Moisture sensor
Step 1: Connection of the Hardware
The Capacivite Soil Moisture sensor has three pin:
1. Ground
2. Vcc
3. Analog output
You can connect this pins to the WEMOS D1 mini in same order:
1. D5
2. D0
3. A0
Step 2: Arduino Source Code
The source code is contains an IoT Guru Cloud integration, you can check out our Tutorials about the integration. You will need:
userShortId
deviceShortId
deviceKey
nodeShortId
fieldName
The code will send an analog measurement in every one minute.
