The WisBlock VOC Sensor RAK12047 uses the Sensirion SGP40 digital gas sensor to provide reliable VOC (volatile organic compound) measurements for indoor air quality monitoring.
This VOC sensor for WisBlock outputs a signal that can be processed by Sensirion’s Gas Index Algorithm, translating raw measurements into a simple VOC Index for easy interpretation.
Key Features & Benefits:
Sensirion SGP40 Sensor: Industry-leading digital VOC sensor for IAQ monitoring
VOC Index Output: Use Sensirion’s open-source libraries and Gas Index Algorithm for easy data interpretation
WisBlock Compatible: Plug-and-play integration with WisBlock Base Boards and Core Modules
Enhanced Accuracy: Combine with temperature and humidity sensors (RAK1901 or RAK1906) for best results
Compact Design: Perfect for smart homes, HVAC systems, and portable air quality monitors
The WisBlock VOC Sensor RAK12047 is ideal for air purifiers, demand-controlled ventilation, smart building automation, and indoor environmental sensing projects.
