Note:

Product images are for illustration purposes only. Actual PCB color, component placement, and module dimensions may vary depending on the manufacturing batch. The MQ-7 sensor requires a warm-up period before providing stable readings and is intended primarily for carbon monoxide (CO) detection. For accurate gas concentration measurements, proper calibration and controlled operating conditions are recommended. Avoid exposing the sensor to water, corrosive gases, or excessive dust for optimal performance.
