The Honeywell HIH-5031-001 is a high-precision, low-power analog humidity sensor designed for reliable environmental monitoring. It provides a linear voltage output (0.8V–3.9V) proportional to relative humidity (0–100% RH) with ±3.5% accuracy. Operating from 2.7V to 5.5V, it is ideal for battery-powered and embedded systems, including HVAC controls, medical devices, and industrial applications. Its fast response time, low drift, and compact SMD package make it suitable for space-constrained designs requiring stable humidity measurements.
