Overview

The SEN54-SDN-T is an integrated environmental sensor node designed to measure particulate matter, volatile organic compounds (VOC), humidity, and temperature in a single module. It utilizes Sensirion's proprietary sensing technology to provide accurate air quality data via a standard I2C interface, operating on a 4.5V to 5.5V supply. This all-in-one solution simplifies the hardware design process for environmental monitoring systems by consolidating multiple sensing elements into a single 52.3mm x 43.3mm x 27.2mm package.

Why Choose This Part

This module reduces BOM complexity by providing four environmental parameters through a single I2C address, eliminating the need for multiple discrete sensors. It features a robust design with internal compensation for temperature and humidity effects on gas and particle readings, and its low standby current of 700uA supports energy-conscious designs.

Applications

HVAC Systems
Integration into smart air conditioning and ventilation units for demand-controlled ventilation based on air quality metrics.
Air Purifiers
Real-time monitoring of PM2.5 and VOC levels to automate fan speed and filtration cycles.
Indoor Air Quality Monitors
Providing comprehensive environmental data for smart home and office wellness dashboards.
Industrial Safety
Monitoring workplace environments for particulate accumulation and organic chemical concentrations.

Getting Started

Engineers can interface with the SEN54-SDN-T using its 6-pin connector and I2C protocol. Sensirion provides comprehensive C and Python drivers via GitHub to facilitate rapid integration with microcontrollers or SBCs. For initial prototyping, the SEK-SEN5x evaluation kit can be used to connect the sensor directly to a PC via a USB bridge.
