CO Sensor MQ7 Breakout with Qwiic
The sensitivity and selectivity of the MQ7 sensor enable it to effectively detect and measure carbon monoxide levels, making it a crucial tool for applications such as gas leakage detection, security systems, and environmental monitoring. By integrating the MQ7 sensor with appropriate electronic circuits and microcontrollers like Dasduino, you can create systems that enable real-time monitoring and prompt alerts in the presence of hazardous CO concentrations. It requires a short time to warm up in order to work correctly.
The breakout board provides digital and analog information through the Qwiic system. Sensor readings are obtained through Qwiic.
Product usage tips:
When gas is detected, the LED will start glowing. It will remain off if it doesn't detect anything. Four mounting holes enable easy mounting to surfaces. The board comes with three male headers.
