Tinycontrol CO2, Temperature and Humidity Sensor on I2C for LAN Controller LK3 and LK4

The advanced sensor allows monitoring of CO2 concentration, temperature, and humidity using photoacoustic technology, which ensures high accuracy and stability of data. This makes it ideal for smart homes, office spaces, or industrial applications where air quality is important. Sensor type SCD40 combines multiple functions in a single module, saving space and simplifying integration into existing systems.

The sensor is equipped with a built-in cable with RJ-12 connector for quick and secure connection to LAN Controller v3 or v4. It supports I2C interface and a power supply voltage of 2.4–5.5 V DC, typically 3.3 or 5 V. With a low current consumption of 175 mA, operation is energy-efficient, allowing long-term environmental monitoring without excessive energy consumption.
