Unipi 1.1 Lite complete set contains all necessary components for installation and initial setup of the Unipi 1.1 Lite controller. Aside from the Unipi 1.1 Lite the set also contains Raspberry Pi computer, Mervis software license, protective cover and other components.
Unipi 1.1 Lite is an extension board for Raspberry Pi computer which allows it to function as a programmable logic controller for monitoring, control and regulation of automation systems. The Lite version is a smaller variant of the standard Unipi 1.1 board and represents the cheapest and simplest way to transform Raspberry Pi into a compact and powerful controller.
Unipi 1.1 Lite complete set is then a practical kit containing everything necessary for installation and powerup of Unipi 1.1 Lite. Aside from the Unipi 1.1 Lite the set also contains Raspberry Pi computer, Mervis software license, protective cover and other components.
Digital inputs (DI) are designed to read binary logic states represented by direct voltage levels. That makes them suitable for reading data from various binary sensors and devices such as switches (on/off), motion sensors (movement detected/not detected), liquid level sensors (full tank/empty tank) etc.
Relay outputs (RO) are primarily used for switching two-state devices with higher current draw such as lightbulbs, thermoelectric valve drives, water heaters, pumps etc.
Unipi 1.1 Lite is powered by the Raspberry Pi computer. The board is compatible with the following Raspberry Pi models:
Note: Unipi 1.1 Lite cannot function without Raspberry Pi
Unipi 1.1 Lite features a single 1-Wire bus for reading data from various 1-Wire sensors (thermometers, humidity meters, light intensity meters etc.). The bus usually utilizes 2-3 conductors and its maximum length can reach up to 200 meters. Up to 15 sensors can be connected to a single bus.
Due to the software openness of Unipi controllers the customer has a wide array of software solutions to choose from and is not limited to a single software.
The main supported platform for programming of Unipi controllers is the Mervis system. Mervis is developed according to the IEC 61131-3 standard for PLC programming and consists of SCADA interface for remote control and monitoring, comprehensible development interface, integrated HMI editor and online/on-premise database for storing data and historical analysis of the controlled technology's operation.
Aside from Mervis, Unipi controllers are also compatible with a wide variety of both commercial and open-source platforms. It is also possible to choose from a large number of open-source platforms, use EVOK API or implement your own code in any programming language.
