Texas Instruments (TI) has introduced the first humidity sensors in a new family designed for automotive and industrial systems that could be potentially damaged by moisture.
The HDC3020 and HDC3020-Q1 will react as needed to changing water vapor conditions over time, which potentially could affect system performance and longevity of devices in vehicles, appliances and medical equipment.
TI said humidity sensor adoption is on the rise due to their ability to extend the life of products, keep automotive cameras clear of fog, control air quality and flow in buildings as well as improve reliability and more comfortable environments.
The sensors preserve data integrity under stress conditions and provide integrated correction to adapt to drift caused by aging, environmental stress and interact with contaminants.
Features of the device include:
- Less than 0.21% RH accuracy drift per year.
- High accuracy across full supply voltage of 1.62 V to 5.5 V.
- Wide temperature and humidity range at 1.5% RH.
Available in pin-to-pin package cover options including removable polyimide tape and permanent IP67-rated filter covers that help protect against dust and moisture.
