So, I'm wanting to create a series of senors in my garden so I can track the soil moisture as well as other climate variables. they will work in client/server relationship and connected using Bluetooth. the Sensors will follow the Bluetooth specifications to ensure compliance incase I was to change the system in the future.
Why? as a fan of big data I want to be able to track the health of my garden overtime and aggregate this data in a graph. This could also one day be plugged into a automated valve to water the garden based off some predefined conditions however I will save that for version two. For now, the measurement of success is:
| Sensor | Description |
|---|---|
| temperture | measure temperture from outside |
| humidity | measure humidity from outside |
| pressure | measure atmospheric preesure |
| soil | measure the moisture from the soil |
These values should be captured from each node and presented as prometheus exporter.
Todo this, I plan to use a:
1 x Raspberry Pi 4
1 x Arduino Nano 33 BLEs each with a Gravity: Analog Capacitive Soil Moisture Sensor
The server will have a custom python 3 service installed and Systemd service that will act a prometheus exporter. hosted on 8000
python3 setup.py install
DELTA 0.0.1
