4. Case study: psychrometer
Design a device for automatic measurement of air humidity and temperature with good accuracy over a temperature range from – 10 °C to 120 °C, using temperature sensors arranged as shown in figure 8 .
The first sensor indicates the air temperature called dry temperature T s as opposed to the wet temperature T h indicated by the second sensor covered with cotton moistened with distilled water. Both sensors are placed in the air duct whose humidity is to be measured
