High-accuracy, fully calibrated digital I2C temperature and humidity sensor with two selectable addresses and an ALERT pin for humidity/temperature threshold monitoring.
Frequently Asked Questions & Transparency
Helpful information about data sources, usage, and privacy
Where does the pinout data and technical specification come from?
The pinout data and technical specifications are based on official manufacturer datasheets as well as publicly available documentation and community resources. As PinoutDatabase is an independent project maintained by me as an individual, I strive for high accuracy, though inadvertent mistakes can still happen.
Can I use the graphics and how are they created?
The SVG vector files and PNG graphics are free to download and use for private/personal purposes. Depending on the component, the diagrams are either crafted manually or generated automatically based on package footprint and pin definitions.
Found an error or missing a component? How can I give feedback?
Community feedback is always appreciated! If you spot an error or are missing a specific component, please use the 'Report Issue' button directly on that component's page or send me a message via the contact form.
Is the site free to use and how is privacy handled?
Currently, using PinoutDatabase is completely free and requires no registration. All interactive web tools run entirely client-side inside your browser. Detailed information regarding data processing can be found directly on our Privacy Policy page.
