ITEM NAME:MQ-7 Carbon Monoxide CO Gas Alarm Sensor Detection Module For Arduino F ITU Descriptio n Description: Mq-7 Fire Alarm Module Of Carbon Monoxide And Combustible Gas Detection Sensor Introduction To Mq-7 Sensors: The Mq-7 Gas Sensor USES A Gas-Sensitive Material Called SnO2, Which Has A Low Conductivity In Clean Air. High And Low Temperature Cycle Detection Method Was Adopted To Detect Carbon Monoxide At Low Temperature (1.5v Heating). The Conductivity Of The Sensor Increased With The Increase Of Carbon Monoxide Gas Concentration In The Air, And The Stray Gas Adsorbed At Low Temperature Was Cleaned At High Temperature (5.0v Heating). The Change In Conductivity Can Be Converted Into An Output Signal Corresponding To The Concentration Of The Gas Using A Simple Circuit. The Mq-7 Gas Sensor Is Highly Sensitive To Carbon Monoxide. It Can Detect A Variety Of Carbon Monoxide Containing Gases And Is A Low-Cost Sensor Suitable For A Variety Of Applications Application: Carbon Monoxide Detector For Home And Environment. Suitable For The Detection Of Carbon Monoxide And Gas. Specifications: 1. Long Size: 32mm X 22mm X 27mm Ii. Main Chips: LM393, Mq-7 Gas Sensor Iii. Working Voltage: 5 Volts Dc Iv. Features: 1. Signal Output Indication. 2. Dual-Channel Signal Output (Analog Output And TTL Level Output) 3. TTL Output Effective Signal Is Low. (When The Output Power Is Low, The Signal Lamp Will Be Bright, Which Can Be Directly Connected To The Single-Chip Microcomputer) 4, The Analog Output Voltage Of 0~5V, The Higher The Concentration, The Higher The Voltage. 5. High Sensitivity And Good Selectivity To Carbon Monoxide. 6, With A Long Service Life And Reliable Stability Package Included: The Sensor Note: 1.Due To The Manual Measurement And Different Measurement Methods, Please Allow 2-3mm Deviation. 2.Please Be Reminded That Due To Lighting Effects And Monitor'S Brightness/Contrast Settings Etc, The Color Tone Of The Website'S Photo And The Actual Item Could Be Slightly Di.Mq-7 Fire Alarm Module Of Carbon Monoxide And Combustible Gas Detection Sensor. The Conductivity Of The Sensor Increased With The Increase Of Carbon Monoxide Gas Concentration In The Air, And The Stray Gas Adsorbed At Low Temperature Was Cleaned At High Temperature (5.0v Heating).
