To connect the Winson MC227D Catalytic Flammable Gas Sensor to a circuit, you will need to follow the pins connection instructions provided in the user manual. One of the detection part pins and one of the compensation part pins should be connected as the signal output. The other pin of the detection part should be connected to the negative electrode, while the other pin of the compensation part should be connected to the positive electrode. Please note that the part with the "D" mark on the sensor bottom is the detection part, and the part with the "C" mark is the compensation part. It is recommended to use handmade welding for soldering, and the soldering conditions should include using rosin soldering flux with minimal chlorine content, a homothermal soldering iron with a temperature below 350℃, and a soldering time of less than 5 seconds. It is important to follow these instructions to ensure proper performance of the sensor.
