MiCS-2714 with measurement circuit (top view)
The voltage measured on the load resistor is directly linked
to the resistance of the sensor. RLOAD must be 820 W at
the lowest in order not to damage the sensitive layer.
MiCS-2714 with recommended supply circuit (top view)
R is 131 . This resistor is necessary to obtain the right
temperature on the heater while using a single 5 V power
supply. The resulting voltages is typically VH = 1.7 V.
