The Carbon Monoxide (CO) Gas Detection Sensor is a high-accuracy and reliable monitoring device designed for industrial safety, indoor air-quality systems, and gas-leak detection applications. It supports multiple output formats including Modbus RTU (RS485), Analog 0–10V, and Analog 4–20mA, making it compatible with PLCs, BMS, EMS, and other automation systems. Powered by a 5V DC supply, the sensor delivers fast response, stable performance, and long-term reliability for real-time CO gas concentration monitoring. Ideal for factories, warehouses, parking areas, HVAC systems, gas-filled environments, and safety monitoring installations.
