However, regression shows linear characteristics towards the line-up of booth sen-

sors. Apart from that accuracy amoung the two sensors in temperature reading is

well demonstrated, but is to be discussed later in this section.

Figure 5.4 shows the humidity proﬁle of both sensors regarding the reference device

of the climate chamber.

Figure 5.4: RH Proﬁle Sensor 1 and Sensor 2

Both sensors indicate quite linear charactericstics and there are just small variances

among the sensors in bands less and greater than 70 % humidity. However, the

actual result shows that readings range within the speciﬁed measuring tolerance of

2 % humidity.
