MQ-7 Sensor Module (Carbon Monoxide Gas)

MQ-7 CO Carbon Monoxide Gas Sensor Module

• Main chip: LM393, MQ-7 gas sensor.
• Operating voltage: DC 3-5V.
• With the signal output indication.
• The dual signal output (analog output, and TTL level output).
• TTL output valid signal is low level, can connected to microcontroller directly.
• 0 ~ 5V analog output voltage, the higher concentration the higher voltage.
• With high sensitivity and good selectivity for CO.
• With a long service life and reliable stability.
• Rapid response and recovery characteristics.
• Size: 33mm*20mm*16mm(L * W * H)
