Carbon monoxide is a dangerous, odorless, and colorless gas that poses serious health risks when inhaled in high concentrations. With the MQ7 sensor, users can easily integrate gas monitoring into their safety, industrial, or DIY projects.At Electroxbd, we bring you original and dependable gas detection modules at competitive prices. Whether you are working on an Arduino project, building a home safety alarm, or developing industrial monitoring systems, the MQ7 sensor offers stable performance and durability.FeaturesWide Range Detection: Capable of detecting CO concentrations from 10 ppm up to 10,000 ppm.High Sensitivity: Designed with SnO₂ sensing material for accurate readings.Dual Output Signals: Supports both analog and digital output, making it compatible with microcontrollers like Arduino and ESP8266.Fast Response and Recovery: Quickly detects changes in CO concentration and resets efficiently.Durable Build: Long life span with stable performance in various environments.Technical SpecificationsGas Detection: Carbon Monoxide (CO)Detection Range: 10 – 10,000 ppmOperating Voltage: 5V DCLoad Resistance: Adjustable with onboard potentiometerOutput Type: Analog and digital signalsPreheat Time: 24 hours for best accuracySensing Material: SnO₂ (Tin Dioxide)Module Size: Compact and easy to integrate with DIY kitsWorking PrincipleThe MQ7 sensor works on the principle of conductivity change in SnO₂ material when exposed to carbon monoxide gas. In clean air, the conductivity remains stable. When carbon monoxide is present, the resistance drops, and the sensor outputs a measurable analog signal.To increase accuracy, the MQ7 sensor operates in a cyclical heating mode. It requires a high heater voltage for a short time to detect CO and then switches to a low heater voltage to maintain stability. This cycle ensures higher sensitivity and reduces false readings.ApplicationsThe MQ7 Carbon Monoxide Gas Detection Sensor is suitable for various applications:Home Safety Systems: Detect CO leaks from stoves, heaters, and fireplaces.Industrial Monitoring: Prevent hazards in factories and manufacturing units.Automobile Safety: Monitor exhaust systems for harmful gas leakage.Arduino & DIY Projects: Build gas alarm prototypes and educational projects.Smart IoT Devices: Integrate into WiFi-enabled systems for real-time gas monitoring.Why Choose MQ7 Sensor from Electroxbd?At Electroxbd, we ensure that every sensor is tested for quality and reliability.
