   <p style="box-sizing: border-box; margin-bottom: 16px;">The gas sensor series is designed to detect various flammable, combustible, and toxic gases in the environment. With pre-calibrated sensors, it can measure the concentration of specific gases quickly and accurately. Supporting multiple output modes, including Analog, I2C, UART, and digital alarm signals, it offers flexibility in different applications. The probes in this series use electrochemical principles, providing strong stability and sensitivity with a lifespan of up to two years.</p>
   <p style="box-sizing: border-box; margin-bottom: 16px;">Using the simple and user-friendly Gravity interface, you can easily build various gas concentration detectors. This sensor series has widespread applications in safety production, industrial manufacturing, and environmental protection, making it the ideal choice for settings such as coal mines, chemical industries, chemical laboratories, and environmental management.</p>

   <h3 id="precautions-for-use" style="box-sizing: border-box; font-family: inherit; line-height: 1.25; color: inherit; margin-top: 24px; margin-bottom: 16px; font-size: 1.25em;">Precautions for use</h3>
   <ul style="box-sizing: border-box; margin-top: 0px; margin-bottom: 16px; padding-left: 2em;">
      <li style="box-sizing: border-box;">The white waterproof and breathable membrane of the sensor on the module is strictly forbidden to open, otherwise it is regarded as artificial damage.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">It is forbidden to plug or unplug the probe with power on.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">It is forbidden to directly solder the pins of the module, but the sockets of the pins can be soldered.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">The module should avoid contact with organic solvents (including silica gel and other adhesives), paints, pharmaceuticals, oils and high-concentration gases.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">The module must not be subjected to excessive shock or vibration.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">The module needs to be warmed up for more than 5 minutes when powered on for the first time. It is recommended to warm up for more than 24 hours if it has not been used for a long time.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">Do not apply this module to systems involving personal safety.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">Do not install the module in environment with strong air convection.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">Do not leave the module in high-concentration organic gas for a long time.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">The data returned by the serial port of the module is the real-time concentration value in the current environment. If there is no standard gas, please do not try the calibration command. This command will clear the calibrated data, and the data returned by the serial port will be inaccurate.</li>
      <li style="box-sizing: border-box; margin-top: 0.25em;">To judge whether the module communication is normal, it is recommended to use a USB to TTL tool (communication level 3V) to observe and judge according to the communication protocol through the serial debugging assistant software.</li>
      </ul>
