What instrument can measure the relative humidity of air?
The relative humidity can be measured by a high molecular capacitive humidity sensor.
Relative humidity, ratio of absolute humidity in the air at the same temperature and absolute humidity saturation, that is a percentage. The percentage of saturated vapor temperature when the absolute humidity of air with the same water temperature, the relative humidity of the air was called. If the absolute humidity of air temperature when using P, P said the same temperature water saturation vapor pressure, relative humidity expressed by B, then a saturation vapor pressure temperature of water can be found out from the table. Therefore, you can calculate the relative humidity when you know the absolute humidity; conversely, you can calculate the absolute humidity by knowing the relative humidity. If the absolute humidity of p=800Pa air, when the temperature is 20 degrees centigrade, the relative humidity of the air is when the temperature is 10 DEG C, the relative humidity of the air in the living room, proper humidity is around 60%. Rice at flowering stage, the most suitable relative humidity is 70% ~ 80%.
