When is Greenheck going to offer larger ... A VOC sensor will detect occupancy at the same level as a CO2 sensor. In other words, if you place a VOC sensor next to a CO2 sensor, the output of the VOC sensor will track the output of the CO2 sensor. Q: retrofits? Doesn’t the ASHRAE standard require me to use CO2? A: ASHRAE does say that CO2 can be used as a method for sensing occupancy, but …
