TINYCONTROL LK4mini I2C + I2C 1-Wire + DIN rail mount

Tinycontrol LAN controller v4 mini I2C + I2C/1-Wire

Compact IoT device for remote monitoring of environmental parameters using digital sensors

LK4mini is an effective solution for remote reading and saving data from digital sensors to a server. The device is equipped with a built-in web server for displaying measured values ​​and configuring settings via a regular 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 version with two I2C buses).

Thanks to its compact dimensions 60 × 58 × 16 mm and power over Ethernet (PoE 802.3af), the device is ideal for industrial and commercial applications requiring reliable monitoring of environmental parameters such as temperature, humidity, atmospheric pressure, CO2 concentration or dust particles.

• I2C bus for connecting sensors via RJ-12 connector and support for DS18B20 temperature sensors on the 1-Wire bus
• Ethernet 10/100 Mbit/s with PoE 802.3af power supply support (mode A, passive mode B with jumper)
• Optional 5 V power supply
• Support for a wide range of sensors including BME280, AM2301B, SPS30, SCD40 and others
• Possibility of mounting on a 35 mm DIN rail
• Operating temperature range -20 to +85 °C

Web interface with rich functionality

The device offers a clear web interface with the ability to customize the dashboard layout for displaying sensor data. Users can configure events, schedule actions, set up the OLED display and manage various communication protocols.

Advanced communication capabilities

LK4mini supports MQTT, HTTP client and SNMP protocols, allows setting up email notifications, access management and firmware updates. Time can be synchronized locally or from the network using NTP.

Wide sensor support

The device is compatible with many types of sensors connected via the I2C bus, including sensors for measuring humidity, temperature, atmospheric pressure, dust particles (PM1, PM2.5, PM4, PM10) and CO2 levels. It also supports the connection of a 0.96" OLED display.
