The Eelectron SM03E02ACC-3 is a plug-in indoor-air-quality sensor in black for the Eelectron presence detector range. It adds a VOC sensor with CO2-equivalent (eCO2) estimation and a −5…+50 °C temperature sensor to a PD00E02KNX Multi, PD00E03KNX Space, PD00E20KNX Wide Range or PD00E21KNX Corridor detector, or to a PD00A02DL2 DALI-2 Multisensor, so demand-controlled ventilation and IAQ monitoring can be added to a room without a second bus device or a separate wall sensor.
The module is powered and read through the host sensor’s smart-sensor input, and its front LED can be set to one of 4 modes to show TVOC concentration bands (off below approx. 1 mg/m³, slow blink to 3 mg/m³, fast blink to 10 mg/m³, steady above). TVOC is measured directly; eCO2 is an algorithmic estimate of CO2 trend from the VOC reading, bounded between 400 and 5000 ppm, and the sensor needs roughly 96 hours of operation to stabilise. Mount the sensor-plus-plug-in pair with the PD00E07ACC double squared ring. The white version is SM03E02ACC; for a true NDIR-style CO2 reading choose SM03E03ACC.
