Hydrogen Sulfide Gas Sensor - MQ-136

Description Attachments

The MQ-136 Hydrogen Sulfide Gas Sensor is a powerful tool for detecting H₂S gas within a range of 1 - 200ppm. It utilizes a SnO2 sensing element, which exhibits lower conductivity in clean air. However, when H₂S gas is present, the sensor's conductivity increases proportionally with the gas concentration. To translate this change in conductivity into usable data, a simple circuit is used, although some calibration may be necessary.

The MQ-136 sensor can be easily soldered using the Gas Sensor Breakout Board from Sparkfun. This board simplifies the process of soldering and ensures a stable and secure connection.

One of the key benefits of the MQ-136 Hydrogen Sulfide Gas Sensor is its high sensitivity and dynamic range. It can detect H₂S gas concentrations as low as 1ppm and as high as 200ppm, making it suitable for a wide range of applications. Whether you're monitoring air quality in an industrial setting or conducting environmental research, the MQ-136 sensor provides accurate and reliable readings.

Another unique feature of this sensor is its SnO2 sensing element. This material offers lower conductivity in clean air, which allows for a more distinct and noticeable change when H₂S gas is present. This characteristic enhances the sensor's performance and accuracy, ensuring that you get the most precise data possible.
