SHIELDPASCO2SENSORTOBO1 is a XENSIV™ PAS CO2 Shield2Go evaluation board that offers a unique customer and evaluation experience – this board is equipped with the XENSIVTM PAS CO2 sensor and comes with a ready to use Arduino library (via GitHub). My IoT adapters are gateways to external hardware solutions like Arduino and Raspberry PI, which are popular IoT hardware platforms. All this enables the fastest evaluation and development of user IoT system. The XENSIVTM PAS CO2 sensor module integrates, on the same PCB, the PAS transducer, a microcontroller for signal processing, algorithms and a MOSFET. Key applications for air quality monitoring and/or demand controlled ventilation are HVAC (heating, ventilation, air conditioning)-residential, commercial, automotive HVAC as well as air purifiers, smart home and building-smart thermostats, lighting and air quality devices and agriculture/greenhouses.
