Description

The SEN50-SDN-T employs Sensirion’s advanced particulate matter sensing technology, utilizing laser scattering and integrated temperature/humidity compensation to deliver precise, stable readings across a 0.3 to 10.0 µm Particle size range. Its all-in-one design simplifies system integration by providing multiple environmental parameters from a single, compact module.

Engineered for long-term reliability, the sensor operates within a 10–40 °C and 20–80% RH window, featuring a very low acoustic emission of 24 dB at 0.2 m. The digital I2C output ensures noise-immune communication with microcontrollers like Arduino, Raspberry Pi, ESP32, and industrial PLCs, making it suitable for demanding monitoring applications.

Key Features

  • Integrated environmental sensing: PM (1.0, 2.5, 4, 10), temperature, and relative humidity.
  • Factory-calibrated PM2.5 accuracy validated against TSI DustTrakâ„¢ standards.
  • Rapid response with a 1-second sampling interval and fast startup (8–30 seconds).
  • Exceptional longevity with a rated lifetime >10 years under continuous operation.
  • Low-noise digital I2C interface with robust EMI/ESD immunity per IEC standards.
  • Compact, lightweight design (52mm x 40mm) for space-constrained installations.
  • Very low acoustic output (24 dB) for quiet operation in sensitive environments.
  • Optimized performance-to-cost ratio for professional and industrial air quality monitoring.

Applications

  • Indoor and outdoor air quality monitoring stations and networks.
  • Demand-controlled ventilation and building management systems (HVAC).
  • Smart home and IoT environmental sensing devices.
  • Industrial process monitoring for cleanrooms and manufacturing.
  • Portable and wearable personal air quality exposure monitors.

Frequently Asked Questions

What is the supply voltage range for the SEN50-SDN-T sensor?

The sensor operates within a supply voltage range of -0.3 to 5.5 V. It is designed for standard 3.3V or 5V logic systems, but care must be taken not to exceed the absolute maximum rating of 5.5V to prevent damage.

How do I communicate with this sensor, and what is the output format?

Communication is via a standard I2C digital interface. The sensor provides fully calibrated, digital readings for all parameters (PM concentrations, temperature, humidity) over the I2C bus, requiring no additional analog signal conditioning.

What is the sensor's response time and sampling rate?

The sensor has a fast 1-second sampling interval. The response time, or time to first valid data after power-on, ranges from 8 to 30 seconds depending on the initial Particle concentration in the environment.

Is the SEN50-SDN-T suitable for outdoor use?

Its operating range is 10–40 °C and 20–80% RH. While robust, prolonged exposure to conditions outside this range (e.g., freezing temperatures, condensation, or direct rain) is not recommended without proper protective enclosure or housing.

Does the sensor require periodic calibration?

The SEN50-SDN-T is factory-calibrated for PM2.5 against TSI DustTrakâ„¢ and features integrated temperature and humidity compensation, designed for minimal drift over its >10-year lifetime. No user calibration is typically required under normal operating conditions.
