<p> The HIH-4021-001 Analog Humidity Sensor is a covered, condensation-resistant, integrated circuit humidity sensor. Humidity sensors are used to provide an indication of the moisture levels in the environment and are very useful for industry processes. The HIH-4000 series sensors are designed to deliver instrumentation-quality RH (Relative Humidity) sensing performance. These sensors have near linear voltage output that allows direct input to a controller or other device. Honeywell sensors are used in a variety of industrial, medical and commercial applications, such as battery-powered systems, meteorology, refrigeration equipment, medical equipment, drying and HVAC equipment, OEM assemblies, among others.</p> <p>The HIH-4021-001 humidity sensor from Honeywell is specifically designed for high volume OEM (Original Equipment Manufacturer) users. This thermoset polymer capacitive sensing element is laser-trimmed for better interchangeability. Its multilayer construction offers resistance to several application hazards like wetting, dust, dirt, oil and chemicals. This Honeywell sensor features a low power design, offers enhanced accuracy, stable, low drift performance and a fast re
