HIH-5030/5031 Series Covered Integrated Circuit Humidity Sensor

The HIH-5030 and HIH-5031 humidity sensors are ideally suited in battery-powered systems where the supply is a nominal 3 V as they can operate down to a low 2.7 V. They have been specifically designed for high volume OEM (Original Equipment Manufacturer) users. These sensors utilise a near linear voltage output making direct input to a controller or other devices possible. They are ideally suited for low drain, battery operated systems with a typical current draw of only 200 μA.

The HIH-5030 is a covered integrated circuit humidity sensor.
The HIH-5031 is a covered, condensation-resistant, integrated circuit humidity sensor that is factory-fitted with a hydrophobic filter allowing it to be used in condensing environments including industrial, medical and commercial applications.
