About this item

The SparkFun BOB-08891 Gas Sensor Breakout is a versatile and easy-to-use sensor board designed to detect a variety of gases in the environment, such as carbon monoxide (CO), methane (CH4), and propane (C3H8). Using a reliable and sensitive gas sensor element, this breakout board is ideal for applications like air quality monitoring, safety alarms, industrial gas leak detection, and environmental research. The breakout includes a simple analog output that varies according to the concentration of the detected gas, allowing straightforward integration with microcontrollers that have analog-to-digital converters (ADCs). The sensor’s response time is rapid, enabling near real-time gas level monitoring. Additionally, the board is designed with a convenient 0.1” pitch pin header for easy breadboarding or soldering onto custom PCBs. Its robust sensor element operates over a wide temperature and humidity range, ensuring reliable performance across diverse environmental conditions. The compact and lightweight design makes it well-suited for portable and embedded applications. While the sensor outputs an analog signal, libraries and example code are readily available to assist users in interpreting and calibrating readings for different gases.
