Honeywell IAQ sensors can connect to existing building automation systems through BACnet/IP, BACnet MS/TP, Modbus RTU and standard outputs like 4-20mA and 0-10VDC. These open protocols can help facilities add advanced monitoring without the need to replace legacy controllers.
For accuracy, our CO₂ sensors are self-calibrating and factory-certified to align with applicable requirements of California Title 24.1, 2 The sensors can feed continuous, up-to-the-minute data into Honeywell's Healthy Building Dashboard, which combines IAQ readings with occupancy counts to help provide zone-level scores and automated alerts.3
