MQ-9 Carbon Monoxide Combustible Gas Sensor Module

Description

• 100% Brand new and high quality gas sensor
• Operating voltage: DC 5V
• Driver IC: LM393 , ZYMQ-9
• Using high-quality dual-panel design, with power indicator and TTL signal output instructions
• With a DO switch signal (TTL) output and AO analog signal output
• TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)
• Analog output voltage, the higher the concentration the higher the voltage
• Hydrogen gas detection with better sensitivity
• There are four screw holes for easy positioning
• Product dimensions: 32(L) * 20(W) * 22(H)
• With a long service life and reliable stability
• Rapid response and recovery characteristics
