To properly connect the Winsen MC114 Catalytic Gas Sensor to your circuit, adhere to these wiring guidelines. First, designate one pin each from the detection part and the compensation part for signal output. Secondly, connect the remaining detection part pin to the negative electrode and the remaining compensation part pin to the positive electrode. Remember that the detection part is identified by the "■" mark. If you are using a separate-type sensor, the detection part is the one with the larger hole. Following these instructions will ensure correct wiring, thus protecting both your Winsen MC114 sensor and your circuit from potential damage.
