7.3.3
Humidity calculation process
The figure below shows the details of the humidity calculation process. The voltage divisor
10
is obtained by multiplying the A/D conversion average by 0.00322 (= 3.3 volts / 2
), because
the A/D converter has 10 bits of resolution. The humidity is found by looking up the voltage
divisor in Table 9.2.3-2, Humidity sensor voltage dividing characteristics table 2
Humidity calculation process
Calculate voltage divisor.
( = ad_average x 0.00322)
Obtain humidity by looking up the voltage divisor in the
humidity sensor voltage division characteristics table.
