Building an Internet connected irrigation system using the particle photon

The particle photon is a cool little wifi device.  It’s relatively inexpensive, it connects to the internet, and I’ve been using it for several components in my smart greenhouse project.  I needed to add a second irrigation system so I recorded how I built the controller and wrote the basic code to make it “web enabled”.

This video guide is incomplete, but it gives the basics on how to get up and running with your own web enabled internet device.

 

Cost breakdown:

Particle Photon – $20
2-port Relay – $7
Electric valve – $30
Case – $9.30
12V power supply – $5
12V -> 5V regulator – $1
Level shifter – $1.50

Total: $73

As a comparison, the Cyber Rain Residential Series 8 zone is $500.  It does control 8 zones, and ours can only control 2.  It also does not come with the electric valves like ours does.  To make a better apples to apples, we’d have to remove the valve from our list and add a bigger relay with more channels.  This relay supports 8 channels and is $9.  We’ll also need an additional level shifter adding another $1.50.  Here’s the new breakdown:

Particle Photon – $20
8-port Relay – $9
Case – $9.30
12V 2A power supply – $5
12V -> 5V regulator – $1
2 x Level shifter – $3

[Apples to “Apples”] Total: $47

Granted, the software of the Cyber Rain is superior.  It supports advanced timers and monitoring.  We don’t have that, but we can add all that by writing more code.  Let me know if you want me to do a walk through on how to add more smarts to the irrigation controller.  I’ve already done it for my setup.

  1. Great tutorial! I’d certainly be interested in learning more about this project. Also, learning about the python code you used to post to your photon would help me.

    Thanks for your hard work!
