The RH sensor is a laser trimmed thermoset polymer capacitive sensing elementThe sensing element's multilayer construction provides excellent resistance to application hazardsUsed in applications in such areas as meteorology, drying, agronomy, instrumentation, etcLinear Voltage Output vs % RH±2% RH accuracy2.54mm lead pitch

Reliably monitor the atmospheric conditions in your workspace with this humidity sensor from Honeywell. It's a capacitive sensor, which measures the changing electrical conductivity of a thin strip of metal oxide to calculate the humidity level in the surrounding air. The electrical system features a near linear voltage output, which means you can set up a direct input to a controller or other device for improved functionality and versatility.

• Wide operating temperature range of -40°C to +85°C makes it suitable for a variety of demanding settings, both indoors and outdoors
• This sensor offers an accuracy of ±3.5% to ensure reliable measurements
• Low current drain of 200μA makes this sensor suitable for battery-operated systems

• Metrology
• Refrigeration equipment
• Medical applications

Yes, you can. The sensing element has a multi-layered construction, which makes it highly resistant to moisture. It's also protected from dust and other small particles as well as chemicals and oil.

The sensor offers a fast response time of just 0.2 seconds, which is particularly suitable for applications where frequent measurements are necessary.
