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