Product Description
The Sensirion SEN55-SDN-T environmental sensor is a high-performance, multi-sensor module designed to measure particulate matter (PM1, PM2.5, PM4, PM10), relative humidity, temperature, volatile organic compounds (VOC), and nitrogen oxides (NOx) concentrations.
Operating between supply voltages of 4.5V and 5.5V, it supports battery or USB power sources and communicates via a digital I2C interface ensuring easy integration into embedded systems.
Its advanced Sensirion Temperature Acceleration Routine (STAR) engine accelerates sensor response to ambient temperature changes, improving measurement speed by a factor of 2-3 times compared to conventional sensors.
The sensor module achieves a temperature accuracy of ±0.45°C and relative humidity accuracy of ±4.5%, making it suitable for critical environmental monitoring applications. It is rated to operate within a temperature range of -10°C to 50°C.
Integrated algorithms enable temperature and humidity compensation as well as VOC and NOx index calculation, delivering output signals fully calibrated and suitable for air quality control systems, HVAC, and air purifiers.
High precision particulate matter sensing with mass concentration precision of ±5 μg/m³ and 5% m.v. for PM1 and PM2.5. Additional measurements for PM4 and PM10 with ±25 μg/m³ precision. Compact design enables easy integration into portable and fixed air quality monitoring devices.
Low power consumption ideal for battery-operated equipment. Suitable for laboratory, industrial, HVAC, and environmental monitoring applications.
The sensor is manufactured in China and is supplied new, ensuring reliable quality for industrial and commercial use. This module is part of Sensirion's SEN5x series, recognized for comprehensive environmental sensing capabilities.
