Sensor Alarm w/ Threshold Control Seven Segment Display

+

NOTE: This project shows a MQ7 CO gas detector in use because this is the only working gas detector that I have. The MQ7 sensor requires an alternating and 5v, which needs to be achieved via pulse width modulation (PWM). That feature is not present in this project, and I intend to substitute a methane sensor (MQ4) for the MQ7 when it arrives from China. FAQ; About; Contact; seawarrior ...
