Size: 32mm X 22mm X 27mm

Main chip: LM393, gas sensor MQ-8

Operating voltage: DC5V

With signal output instructions.

• Dual signal output (TTL output and analog output)
• The TTL output has a valid signal at a low level.
• Analog voltage 0 ~ 5V, the higher the concentration, the higher the voltage.
• High sensitivity to hydrogen.
• Can withstand moisture from ethanol, LPG (oil), and smoke interference.
• Continuous lifespan and reliable stability.
• Fast response and recovery characteristics.
