PRODUCT FEATURES
A54-24 CO2 Sensor
- Dedicated CO2 Monitoring: The A54-24 uses NDIR infrared technology to provide stable and reliable carbon dioxide measurement for your indoor air quality and ventilation control systems.
- Wide CO2 Measurement Range: The sensor measures CO2 from 400–9,999 ppm with 1 ppm resolution and an accuracy of ±(50 ppm + 5% of reading), supporting precise monitoring across changing indoor conditions.
- Flexible Communication Interfaces: The A54-24 supports RS485 and UART communication interfaces, with expandable Modbus protocol support. Powered by 12–24 VDC, it provides stable data transmission for system integration.
- Compact and Durable HVAC Design: Measuring only 66.4 × 51.4 × 19 mm, the sensor features a flame-retardant PC+ABS V0 housing and a low average power consumption of ≤1 W. Its compact construction simplifies installation in space-constrained commercial and industrial air quality equipment.
