  MQ8-Hydrogen Gas Sensor Module

  ₹165.00 Original price was: ₹165.00.₹135.00Current price is: ₹135.00.

  Quick Review:

  • Operating Voltage: 5V DC (typically).
  • Sensor Resistance: The resistance of the sensor element changes with gas concentration, usually between a few kΩ and several hundred kΩ.
  • Sensitivity Range: Can detect hydrogen gas concentrations from 100 to 10,000 ppm.
  • Response Time: The sensor typically responds within a few seconds to changes in gas concentration, but it requires 1-2 minutes of preheating for optimal performance.

  Shipping: Usually delivered in 3-7 days.
