SmartPID M5 mini Concept
The basic idea behind SmartPID m5 mini controller is to separate the control unit from the power relays. This
provides great flexibility, reduces wirings complexity.
SmartPID M5 can run all the control process (temperature and humidity control) autonomously and drives
wirelessly a smart relay that is connected to load and can be locate in a different place.
At the same time SmarPID m5 is cloud connected via wifi and can be fully controlled from remote web app.
Despite the compact size, SmartPID m5 is feature rich with different control mode and algorithms, support of
different sensor types, brilliant display with simple GUI and easy setup.
