DESCRIPTION The HIH-5030/5031 Series Low Voltage Humidity Sensors operate down to 2.7 Vdc, often ideal in battery-powered systems where the supply is a nominal 3 Vdc. The HIH-5030/5031 Series delivers instrumentation-quality RH (Relative Humidity) sensing performance in a competitively priced, solderable SMD. The HIH 5030/5031 complements our existing line of 5 Vdc SMD (Surface Mount Device) humidity sensors. SMD packaging on tape and reel allows for use in high volume, automated pick and place manufacturing, eliminating lead misalignment to printed circuit board through-holes. 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 many condensing environments including industrial, medical and commercial applications. The HIH-5030/5031 Series Humidity Sensors are designed specifically for high volume OEM (Original Equipment Manufacturer) users. The RH sensor uses a laser trimmed, thermoset polymer capacitive sensing element with on-chip integrated signal conditioning. Direct input to a controller or other device is made possible by this sensor s near linear voltage output. With a typical current draw of only 200 A, the HIH-5030/5031 Series is ideally suited for many low drain, battery operated systems. The sensing element's multilayer construction provides excellent resistance to most application hazards such as condensation, dust, dirt, oils and common environmental chemicals. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. Sample packs are available. See order guide.

When liquid water falls on the humidity sensor die, output goes to a low rail condition indicating no humidity. 4. Total accuracy including interchangeability is 3 %RH. 2 Typical 7 3 +3 General Notes: Sensor is ratiometric to supply voltage. Extended exposure to >90 % RH causes a reversible shift of 3 % RH. Sensor is light sensitive. For best performance, shield sensor from bright light. Figure 1.
