Overview

The Honeywell HIH-4000-003 is a precision, board-mount humidity sensor from the HumidIcon series, designed for through-hole mounting in a compact SIP-3 package. This analog output sensor provides a linear voltage output proportional to relative humidity across a full 0% to 100% RH range, with an accuracy of ±3.5% RH. Operating from a 4V to 5.8V supply while drawing only 200 µA, it is ideal for low-power environmental monitoring applications. The HIH-4000-003 is suitable for HVAC, medical equipment, and industrial control systems where reliable, long-term humidity measurement is required. Its laser-trimmed thermoset polymer capacitive sensing element ensures excellent stability and resistance to condensation, making it a robust choice for demanding environments.

Features

High RH Range: 0% to 100% RH measurement capability, covering full-scale humidity conditions without saturation.
Low Power Consumption: 200 µA typical operating current, enabling energy-efficient designs for battery-powered systems.
Analog Output: Linear voltage output simplifies interface with microcontrollers or ADCs, requiring no complex digital protocol decoding.
Wide Supply Voltage: 4V to 5.8V supply range provides flexibility for integration with standard 5V logic systems.
Condensation Resistance: Robust thermoset polymer sensor withstands condensation and harsh environments, ensuring long-term reliability.

Pin Configuration and Functions

Pin1: VDD - Supply voltage input, connect to 4V to 5.8V DC power source.
Pin2: VOUT - Analog output voltage proportional to relative humidity, typically 0.8V to 3.9V for 0% to 100% RH.
Pin3: GND - Ground reference, connect to system ground plane.

Typical Applications

HVAC Systems: Air quality monitoring and humidity control in residential and commercial building automation.
Medical Equipment: Respiratory therapy devices and incubators requiring precise humidity measurement.
Industrial Process Control: Environmental monitoring in clean rooms, storage facilities, and manufacturing lines.
Weather Stations: Outdoor environmental sensing for meteorological data collection and forecasting.

Equivalent / Alternative Parts

HIH-4000-001 (Honeywell): Same SIP-3 package and 0-100% RH range, but with ±3.5% accuracy and different output voltage scaling.
HIH-4000-002 (Honeywell): Pin-to-pin compatible, same accuracy and supply range, optimized for specific calibration curves.

Design-in Tips

Filter Capacitor Placement: Place a 0.1 µF ceramic capacitor close to Pin1 (VDD) and Pin3 (GND) to reduce power supply noise and ensure stable output.
Airflow Consideration: Avoid sealing the sensor in a closed housing; provide ventilation slots to allow ambient air to reach the sensing element for accurate readings.
Output Loading: Connect VOUT to a high-impedance load (>10 kΩ) to prevent output voltage droop and maintain specified accuracy.

Wiki Reference

Soil moisture sensors are devices that measure the amount of water present in the soil. Rather than directly measuring the moisture content by physically removing, drying, and weighing a sample, these sensors indirectly determine the volumetric water content by utilizing other soil properties such as electrical resistance, dielectric constant, or interaction with neutrons. The relationship between the measured property and soil moisture needs to be calibrated and can be influenced by factors like soil type, temperature, and electrical conductivity. Reflected microwave radiation, which is affected by soil moisture, is utilized for remote sensing in hydrology and agriculture. Farmers and gardeners can use portable probe instruments to monitor soil moisture levels. While soil moisture sensors primarily focus on measuring volumetric water content, there are also sensors that measure another property of moisture in soils known as water potential, such as tensiometers and gypsum blocks.
