Basic Circuit
Fig2. WSP2110 Test Circuit
Instructions:The above fig is the basic test circuit of WSP2110.The sensor requires two voltage inputs: heater
voltage(V
H
) and circuit voltage(V
C
). V
H
is used to supply standard working temperature to the sensor and it can
adopt DC or AC power, while V
RL
is the voltage of load resistance R
L
which is in series with sensor. Vc supplies the
detect voltage to load resistance R
L
and it should adopts DC power.

Rs means resistance in target gas with different
concentration, R
0
means resistance ofsensor in clean air. All
tests are finished under standardtestconditions.
Fig4.Typical temperature/humiditycharacteristics
Rs means resistance of sensor in 10ppm tolueneunder
different tem. and humidity. Rsomeans resistance of the
sensor in clean air under 20℃/55%RH.
