Abstract
A moisture detector includes a sensor chip and a moisture determining unit. The sensor chip includes a humidity detector having a detection surface on which to measure humidity, and also includes a heater heating the detection surface, and the moisture determining unit is configured to, after causing the heater to start heating, determine whether moisture is present on the detection surface based on a difference in changes in the humidity measured by the humidity detector.
Claims15
A moisture detector comprising:
- a sensor chip including a humidity detector and a heater, the humidity detector having a detection surface on which to measure humidity, and the heater heating the detection surface;
- and
- a moisture determining unit configured to, after causing the heater to start heating, obtain the humidity, measured by the humidity detector, a plurality of times at predetermined time intervals, and determine that moisture is present on the detection surface in a case where an average value of the humidity obtained the plurality of times is greater than or equal to a threshold.
A moisture detector comprising:
- a sensor chip including a humidity detector and a heater, the humidity detector having a detection surface on which to measure humidity, and the heater heating the detection surface;
- and
- a moisture determining unit configured to, after causing the heater to start heating, obtain the humidity, measured by the humidity detector, a plurality of times at predetermined time intervals, and determine that moisture is present on the detection surface in a case where a number of consecutive times a differential value becomes greater than or equal to a reference value is greater than or equal to a reference number of times, the differential value being calculated between readings of the humidity obtained at two consecutive times.
A moisture detection method using a sensor chip including a humidity detector and a heater, the humidity detector having a detection surface on which to measure humidity, and the heater heating the detection surface,
- causing the heater to start heating, and subsequently obtaining the humidity, measured by the humidity detector, a plurality of times at predetermined time intervals, and determining that moisture is present on the detection surface in a case where an average value of the humidity obtained the plurality of times is greater than or equal to a threshold.
