Summary of MQ-7 CARBON MONOXIDE ALARM CIRCUIT PIC16F88
This article describes a carbon monoxide alarm circuit using an MQ-7 sensor and PIC16F88 microcontroller. Operating at 12V DC, the system detects CO levels and activates a relay to trigger external devices like sounders or lamps when thresholds are exceeded. The project includes schematic PCB designs and assembly source code for implementation.
Parts used in the MQ-7 Carbon Monoxide Alarm Circuit:
- MQ-7 Carbon Monoxide Sensor
- PIC16F88 Microcontroller
- 12V DC Power Supply
- 12V Relay
- Sounder

MQ-7-CO While carbon dioxide (CO2) is not poisonous as such (in fact the air we breathe naturally contains around 0.03% carbon dioxide), in sufficient quantity it can displace oxygen in the air and therefore cause suffocation.
