Product Description
SEN5x Environmental Sensor Node
The SEN5x is an advanced environmental sensor node designed for HVAC and air quality applications. It integrates multiple sensing capabilities, including particulate matter (PM), NOx, VOC, relative humidity (RH), and temperature (T). This platform offers fast and easy integration with a single driver for up to 8 data signals, superior sensing accuracy, and a long lifetime. The fully calibrated digital output simplifies implementation in various systems.
