TI Introduces New Family of Humidity Sensors

Texas Instruments (TI) has rolled out the first devices in a new family of humidity sensors that provide the industry’s highest reliability and accuracy and the lowest power consumption – along with built-in protection of sensing elements.

TIThe HDC3020 and HDC3020-Q1 will allow engineers to create more reliable industrial and automotive systems that withstand potential damage caused by moisture, and react as needed to changing water vapor conditions over time.

Offering improved relative humidity measurement accuracy with reduced long-term error, when compared to existing RH sensors, the HDC3020 and HDC3020-Q1 preserve data integrity under stress conditions and are the industry’s first to provide integrated correction to adapt to drift caused by natural aging, environmental stress, or interactions with contaminants.

Extend system reliability with enhanced sensing elements

The HDC3020 and HDC3020-Q1 achieve lower drift in extreme conditions than competing devices, with less than 0.21% RH accuracy drift per year and less than 5% RH drift from temperature and humidity stress (tested up to 85% RH and 85°C). This sustained accuracy enables longer system lifetimes, eliminating the need to frequently replace or recalibrate the sensor.

Increase system efficiency with the industry’s highest accuracy

The HDC3020 and HDC3020-Q1 provide the highest accuracy – verified with a procedure traceable to the National Institute of Standards and Technology – across the full supply voltage of 1.62 V to 5.5 V and the widest temperature and humidity range at ±1.5% RH. This high accuracy enables more precise control of a system, increasing efficiency by ensuring that the system only runs when necessary.

Additionally, the HDC3020 and HDC3020-Q1 are available in several pin-to-pin compatible package cover options, such as removable polyimide tape and permanent IP67-rated filter covers.

Increase lifetimes for battery-operated systems with the industry’s lowest-power humidity sensors

Ultra-low power consumption (nano ampere) across a wide supply range from 1.62 V to 5.5 V enables low-power operation both while a system is actively running and in sleep mode.
