ELEKTROBOCK Air Quality Sensor SN121-AN

The ELEKTROBOCK SN121-AN is an indoor air quality sensor designed to monitor CO₂ concentration and control ventilation or heat recovery based on current needs. It's suitable for homes, offices, schools, meeting rooms and other indoor spaces, where it helps maintain a more pleasant and healthier environment. The sensor uses the NDIR principle for CO₂ measurement, offers five levels of LED air quality indication and an analogue output of 0–10V. It also features automatic calibration, a 10-minute BOOST mode, and a night-time dimming function for the LED indicator, which reduces distracting light in bedrooms or children's rooms, for example.
