The analog version of the Nose® has three sensors for measuring and monitoring indoor air quality (IAQ) parameters - temperature, humidity, or carbon dioxide (CO2). The sensors are on one circuit board with field-selectable 0-10VDC or 4-20mA outputs. It can be integrated into legacy building automation systems. The unit's temperature sensor accuracy is ±0.5°C, the humidity sensor accuracy is ±2 percent, and the CO2 sensor accuracy is ±5 percent. The product is mounted at a height similar to that of a thermostat, typically in close proximity to the return air duct on a wall representative of the breathable air space in the area being monitored.
