HUABAN Gas Detectors & Alarms MQ-139 Editorial Review
This review provides an in-depth analysis of the MQ-138 gas sensor module, which is suitable for tracking changes in VOC levels in real-time, detecting their presence or setting an alarm at a certain gas threshold. In particular, the module is sensitive to acetone fumes, but it does not provide precision readings for PPM. While the MQ-138 is not super accurate, it is very reactive to gases and provides useful data. It has a preheat time of 48 hours but does not necessarily need to be heated for hours on end every time it is powered on. It is a variable resistor and has humidity and temperature influences, but the resistance of the sensor component stabilizes after 24 hours. The MQ-138 works as a stand-alone module, emitting an LED signal for specific concentration levels but needs an analog pin (AOUT) for approximations of the actual gas level, which can be achieved by using an Adruino or MCP3008. The pinout on the sensor component is also discussed. Finally, a drawback of this module is the long warm-up time, several hours, and its relative inaccuracy for ppm readings.
