About the CO-sensor-MQ7-breakout with easyC-hardware design

CO-sensor-MQ7-breakout with easyC-hardware design is an open source AVR/Arduino PCB design by SolderedElectronics, published on GitHub under the TAPR-OHL-1.0 license. It is a 2-layer board measuring 22 × 54 mm, with 26 components from 16 distinct parts.

Its main chip is the ATTINY404-SSNR, from the AVR/Arduino family. Other key parts include the MQ-X, NMOS-DUAL and TPS613222A. By type, the board carries 6 resistors, 4 ICs, 4 relays, 4 capacitors, 2 jumpers and 1 diode.

It belongs with the sensors and dev boards & breakouts designs in this gallery.

From the project

Hardware design, BOM, gerbers and 3D files for CO-sensor-MQ7-breakout-with-easyC designed by Soldered Electronics.

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.
