Typical Applications for the MQ-7 Carbon Monoxide Gas Sensor Module: The MQ-7 Carbon Monoxide Sensor Module is an excellent investment for any environment in which carbon monoxide may build up to toxic levels. Environments like these include workshops, laboratories, underground rooms or even garages where vehicles are parked or stored.

In this work, geopolymer synthesized with perlite and an alkaline activator medium was evaluated as a new adsorbent and photocatalyst for degradation of methylene blue (MB) dye from an aqueous medium. The functional group, the structure, and the morphology of the raw and the synthesized materials were characterized using FT-IR, XRD, and SEM analysis.

In [14], a gas detection system employing an MQ-9 sensor was proposed. The study developed an embedded system that triggers a buzzer and a set of LEDs to alert residents in the event of a gas leak. An android based automatic gas detection and indication robot was developed by [15]. When gas leak is

When it comes to lifesaving gas detectors, you can't afford to guess. Gas detectors today offer features that provide clear information on the instrument status and sensors, tell the user how to react when an alarm goes off, and make it easy to interpret the readings. This white paper covers technology that makes gas detection easy for all users.
