About This Project
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.
