SparkFun Particle, VOC, Humidity, and Temperature Sensor - SEN54

The SEN54 sensor module from Sensirion combines the measurement of particulate matter, VOC, humidity, and temperature in a single package. The SEN54 sensors provide fully calibrated outputs with a digital interface, a strong lifetime under 24 h/day operation, and a compact form factor. The combination of all measurement parameters in a single device allows users to reduce design and integration efforts, shorten development times and simplify supply chain. Additionally, the included Sensirion Temperature Acceleration Routine (STAR) engine accelerates the device�s response to ambient temperature change by a factor of 2-3 to provide better UX and more accurate measurements to end users.

The SEN54 uses the the GHR style 'locking' JST connector. This module includes a 6-pin compatible cable that is terminated in breadboard pins making it very easy to connect to the SEN54. The only downside is that we use our generic 6-pin GHR cable and the wire colors do not match normal 'red for 5V' sort of connections. Please see this image for the correct wire color and pin function.

Note: The SEN54 uses I2C to communicate at 3.3V but requires 5V for power. We recommend the Qwiic Boost to connect this sensor easily to our Qwiic system.
