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 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-5030/5031 Series Humidity Sensors are designed spec.

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 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-5030/5031 Series Humidity Sensors are designed specifically for high volume OEM (Original Equipment Manufacturer) users. 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. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. FEATURES Operates down to 2.7 Vdc, often ideal in battery-powered systems where the supply is a nominal 3 Vdc. Tape and reel packaging allows for use in high volume pick and place manufacturing (1,000 units per tape and reel) Molded thermoset plastic housing Near linear voltage output vs %RH Laser trimmed interchangeability Low power design Enhanced accuracy Fast response time Stable, low drift performance Chemically resistant The HIH-5030/5031 Series delivers instrumentation-quality RH (Relative Humidity) sensing performance in a competitively priced, solderable SMD. 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 RH sensor uses a laser trimmed, thermoset polymer capacitive sensing element with on-chip integrated signal conditioning. The sensing element's multilayer construction provides excellent resistance to most application hazards such as condensation, dust, dirt, oils and common environmental chemicals. Sample packs are available. See order guide.
