Sensirion NOx, PM, RH, VOC Environmental Sensor for Particulate Matter, Relative Humidity, Temperature, VOC SEN55-SDN-T

The Sensirion SEN55-SDN-T is a high-performance environmental sensor designed to measure nitrogen oxides (NOx), particulate matter (PM1, PM2.5, PM4, PM10), relative humidity, temperature, and volatile organic compounds (VOC) with outstanding precision. Operating on a supply voltage of 4.5 to 5.5 volts and featuring low power consumption, this sensor is ideal for use in industrial, HVAC, air quality monitoring, air purifiers, and environmental laboratories.

Equipped with Sensirion’s proprietary STAR engine, the sensor provides fast ambient temperature response times accelerated by a factor of 2 to 3. The module communicates through a digital I2C interface, allowing integration with systems that require fully calibrated sensor outputs over up to eight data signals.

The sensor module includes integrated algorithms for temperature and humidity compensation, VOC index, and NOx index calculations, ensuring reliable and precise air quality data. It provides mass concentration accuracy of ±5 micrograms per cubic meter for PM1 and PM2.5 and ±25 micrograms per cubic meter for PM4 and PM10 particulate matter.

With operating temperature capability ranging from -10°C to 50°C and manufactured in China, the SEN55-SDN-T supports applications requiring environmental sensing under varied conditions.

This product is delivered new and contains robust sensing capabilities for particulate matter, relative humidity, temperature, VOC, and nitrogen oxide concentration detection, making it a compact and comprehensive all-in-one air quality sensor solution.

Applications include industrial environmental monitoring, smart building HVAC systems, air purification units, and laboratory instrumentation requiring precise environmental parameter measurement.
