This is an amazing Arduino Carbon Monoxide Sensor. It uses an MQ7 probe to detect carbon monoxide (CO) concentrations in the air ranging from 20 to 2000ppm. You can easily adjust the sensitivity via the potentiometer, and the output is proportional to the gas density. You can simply use analog reading to get data from this sensor. To make it super easy to use, it comes with a Gravity Interface for plug-and-play. The Arduino IO expansion shield is the perfect match when connecting this sensor to your Arduino microcontroller. Specifications include a 5V power supply, an analog interface, a pin definition of 1-Output, 2-GND, 3-VCC. It has high sensitivity to carbon monoxide, fast response, and is stable with a long life. Its size is 40x20mm (1.57'x0.79'). You'll also get access to documents like the Wiki, MQ7 datasheet, and schematic. The shipping list includes 1 unit of the Carbon Monoxide Sensor (MQ7).
Using this Arduino Carbon Monoxide Sensor is a breeze. First, connect it to your Arduino microcontroller with the help of the Arduino IO expansion shield as it's the best match. The Gravity Interface allows for easy plug-and-play, so you don't have to worry about complex set - ups. Once connected, power it with 5V. You can adjust the sensitivity using the potentiometer according to your needs. To get data about carbon monoxide levels, use analog reading. When it comes to maintenance, keep it in a clean environment to ensure its long - term performance. Avoid exposing it to extreme temperatures or humidity. If you need more detailed information, refer to the Wiki, MQ7 datasheet, and schematic provided.
