Compact IoT device for remote monitoring of environmental parameters using digital sensors.
LK4mini is an efficient solution for remotely reading and storing data from digital sensors to a server. The device features a built-in web server for displaying measured values and configuring settings via a standard web browser. It is available in two versions: with two I2C buses, or with a combination of I2C and RS-485 with Modbus RTU protocol support (this model is the Modbus version).
Thanks to its compact dimensions of 60 × 58 × 16 mm and Power over Ethernet (PoE 802.3af) power supply, the device is ideal for industrial and commercial applications requiring reliable monitoring of environmental parameters such as temperature, humidity, atmospheric pressure, CO2 concentration, or particulate matter levels.
Feature-rich web interface
The device offers a clear web interface with customizable dashboard layouts for displaying sensor data. Users can configure events, schedule actions, set up the OLED display, and manage various communication protocols.
Advanced communication options
LK4mini supports MQTT, HTTP client, and SNMP protocols, allows configuration of email notifications, access management, and firmware updates. Time can be synchronized locally or from the network via NTP.
Wide sensor support
The device is compatible with many types of sensors connected via the I2C bus, including those for measuring humidity, temperature, atmospheric pressure, particulate matter (PM1, PM2.5, PM4, PM10), and CO2 levels. It also supports connection of a 0.96" OLED display.
