The HIH-4000 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 µA, the HIH-4000 Series is often ideally suited for low drain, battery operated systems. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. Individual sensor calibration data is available

The HIH-4000-003 is a high-performance, analog-output relative humidity (RH) sensor designed for accurate, stable, and cost-effective environmental monitoring. It provides a direct, near-linear voltage output proportional to the measured humidity, simplifying signal processing in both analog and digital systems. This sensor is factory-calibrated for precision, minimizing the need for additional calibration during integration. Its small form factor and low power consumption make it ideal for portable, battery-powered, or embedded applications. Designed to operate reliably in various environmental conditions, it is well-suited for HVAC systems, weather monitoring devices, medical instrumentation, and industrial control equipment.
