The project was created to control electrodes distributed in the field, as well as the control of the pump (on / off and pressure) according to the condition (1 or 0) of the 18 solenoid valves through a frequency converter siemens. Thanks to Cayenne the project was achievable in a short time.
Pressure sensor SIMATIC P222 from 4 to 20 mA, modules realy x8, raspberry pi 3 x2, inverter of logic states, electrovalves + audio visual pilot. Access point x 3 for internet links.
(Hardware, sensors, actuators, device model, WiFi, etc.)
Triggers & Alerts
Yes, to replicate GPIO status between the 2 raspberry pi for decision making to ignite or to pay the motor of the irrigation pump. Valve condition = 1 then motor = 1. yes no = 0. The alerts notifies the engine start and irrigation activation via sms and mail.
Here irrigation is programmed during the weekend when there is no operator. Very useful.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!e!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
