This carbon monoxide gas sensor uses a simple circuit to convert conductivity changes caused by CO concentration into electrical output signals. With a 5 ppm to 5,000 ppm detection range, this compact MEMS CO sensor is suitable for carbon monoxide leak detection and monitoring in residential, commercial, and industrial applications. Its space-saving design enables easy integration into CO detectors, gas monitoring instruments, and embedded safety devices for the U.S. and global markets.
Lightweight and Space-Saving
- Ultra-Compact Sensor Design: SISCO carbon monoxide sensor features a miniaturized sensing element with a very small footprint, making it suitable for space-constrained gas detection equipment.
- Lightweight and Space-Saving: Its compact construction helps reduce the overall size and weight of the sensing module, ideal for portable and embedded CO detection devices.
- Sensitive Sensing Element: The exposed sensing surface is designed to interact with carbon monoxide gas, supporting responsive CO detection in various gas monitoring applications.
- Easy PCB Integration: The small sensor form factor allows convenient integration into circuit boards and compact gas detection systems.
- Suitable for Embedded Applications: Its miniature size makes the sensor well suited for gas alarms, air-quality monitoring devices, industrial detectors, and other CO sensing equipment.
Distinctive Golden Contact Pads
- Standard SMT Carrier Tape Packaging: The sensors are neatly arranged in a black, perforated carrier tape, which is the industry-standard packaging for surface-mount components. This design is fully compatible with high-speed automated pick-and-place machines, ensuring efficient, precise, and dust-free mass production.
- Distinctive Golden Contact Pads: Unlike the continuous pads seen in some other models, the SISCO carbon monoxide sensor features a unique array of small, dot-matrix-style golden solder pads on its surface. This specific layout provides a larger soldering area, ensuring stronger mechanical adhesion and more stable electrical signal transmission when mounted on a PCB.
- Robust Black Ceramic/Molding Package: Each sensor is housed in a square, black, solid package. This material offers excellent resistance to high temperatures and harsh chemical environments, effectively protecting the sensitive internal sensing elements from damage during the reflow soldering process and throughout the product's lifecycle.

Q1: What is a CO gas sensor?
A1: A CO gas sensor is a sensing device designed to detect and measure carbon monoxide (CO) concentrations in the air. It is commonly used in gas detection systems, safety monitoring equipment, industrial instruments, and indoor air quality applications.
Q2: What does a CO gas sensor detect?
A2: A CO gas sensor is specifically designed to detect carbon monoxide (CO). It measures the concentration of CO in the surrounding environment and provides a corresponding electrical signal for monitoring or alarm systems.
Q3: How does a CO gas sensor work?
A3: SISCO CO gas sensors use a sensing element that reacts with carbon monoxide and produces a measurable electrical signal. The signal changes according to the concentration of CO, allowing the connected instrument or control system to determine the gas level.
Tips: What is the difference between a CO sensor and a CO detector?
A CO sensor is the core sensing component responsible for detecting carbon monoxide in the surrounding environment. It responds to the presence and concentration of CO and converts the detected gas concentration into an electrical signal, which can then be processed by an external circuit or control system. A CO sensor by itself generally does not include an alarm, display, power management, or user interface.
A CO detector is a complete carbon monoxide detection device that incorporates a CO sensor together with electronic circuits and other components. It typically processes the sensor signal, evaluates the CO concentration, and provides visual, audible, or digital alerts when the concentration reaches a predefined threshold. In simple terms, the CO sensor performs the gas sensing, while the CO detector uses that sensing element to provide a complete monitoring and alarm function.
