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.
