*Please note: Prior to purchasing please make sure to check the specifications to see all compatible sensors as shown below in the "works with these sensors" list*

Use the CM-200 as an Arduino Shield with the example code provided in this repository can rapidly get a prototype running for interfacing our most popular sensors with Arduino Uno and Arduino Mega. or use the CM-200 as a Raspberry Pi Hat to prototype using the Raspberry Pi ecosystem.

Finally, users can develop production ready code with the onboard STM32WB55, with available BLE, USB, User LEDs, User Buttons, and multiple communication protocols.is designed to make it easy to use our most popular gas sensors.

For quick, real-time data analysis use the GasLab® Data logging software. Plug in a sensor, plug the PCB into a PC's USB port, and begin to graph and store data as industry standard .csv files in minutes for project analysis, trends and reporting.

Whether you are evaluating production code, building prototypes, doing data analysis or are in need of a full software development platform, the CM-200 is the right technology for you.

Please note: To ensure safety and proper operation, please observe precaution regarding electrical components on the CM-200 near other metal materials.
