SENSOR Detects Hydrogen MQR1003AH

MQR1003-A-H Package :A Detects Hydrogen


The MQR1003 is a kind of n-type semiconductor gas sensor
based on tin dioxide (SnO2). When this sensor is powered on,
and it is exposed to a combustible gas, the resistance between A
and B will reduce, and the variation is related to the
concentration of combustible gas. Because of its especially high
sensitivity to methane, propane and butane, the MQR1003 is
very practical for Natural Gas and LPG monitoring.
The MQR1003 is most practically employed in a circuit design,
which maintains circuit voltages at fixed values under 15V and with the heater
voltage stabilized at 5V. These voltage ratings are very practical when
determining your design specifications because of the wide range of available
components. This makes the use of the MQR1003 an especially way to design
low-cost, highly reliable gas detection circuits.
