Show Product Description

Enhance the safety of your home, office, or workspace with the MQ-2 Gas and Smoke Sensor (CO/LPG model), featuring a compact size of 32×22×27 mm. This advanced sensor from the renowned MQ brand offers reliable and precise detection of hazardous gases and smoke, making it an essential addition to any environment where air quality and safety are a priority. Technical Specifications: The MQ-2 sensor is engineered to detect and measure a wide range of gases, including Liquefied Petroleum Gas (LPG), alcohol, propane, hydrogen, carbon monoxide (CO), and even methane. The module version is equipped with a digital pin, enabling the sensor to operate independently from a microcontroller—ideal for simple setups or when detecting a single type of gas. For accurate gas concentration measurement in parts per million (ppm), the analog pin can be used, which operates at 5V and is compatible with most microcontrollers such as Arduino. Key Features: - Built-in power indicator LED and low TTL indicator LED for easy status monitoring. - Operating voltage: 5V, ensuring compatibility with a wide range of electronic circuits. - Capable of detecting multiple hazardous gases. - Analog output voltage range: 0V to 5V; Digital output: 0V or 5V (TTL logic). - Quick preheat time of just 20 seconds. - Adjustable digital pin sensitivity via an integrated potentiometer. - Compact dimensions: 32 mm (L) × 22 mm (W) × 27 mm (H); lightweight at only 10 g. Use Cases: The MQ-2 sensor is ideal for air quality monitoring, gas leak detection in kitchens, factories, hospitals, laboratories, and offices. It can also serve as a safety alarm system in public and residential spaces, helping to uphold safety standards and reduce the risk of accidents caused by gas leaks or smoke. Benefits: - Provides effective protection for lives and property from gas and smoke hazards. - Easy to integrate and install with smart systems and popular platforms like Arduino. - High accuracy and rapid response to changes in air quality. - Flexible for use as either a digital or analog sensor depending on your needs. Care Instructions: Install the sensor in a well-ventilated area, away from excessive moisture and dust for optimal performance. Clean periodically with a soft brush, avoiding strong liquids. Regularly check electrical connections to ensure safe operation. If the indicator LED stops functioning or readings become inaccurate, consider replacing the sensor or checking the electronic circuit. Origin: China Brand: MQ Model: MQ-2 CO/LPG Suitable Environments: Kitchens, offices, factories, hospitals, laboratories, homes
