Smart Sensor AR867 LCD Digital Hygrometer Thermometer Dual Humidity Temperature Meter Indoor Outdoor Tester Weather Station with Calendar & Clock Alarm SMART SENSOR Temperature Humidity Meter is an instrument used for measuring the moisture content in the atmosphere. Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can lead to a measurement of humidity.
