# `hts221` > I²C API for the HTS221 humidity and temperature sensor # [Documentation](https://docs.rs/hts221) # Example To use the driver, you must have a concrete implementation of the [embedded-hal](https://crates.io/crates/embedded-hal) traits. This example uses [linux-embedded-hal](http://crates.io/linux-embedded-hal): ``` rust let mut i2c = I2cdev::new("/dev/i2c-1")?; let mut hts221 = hts221::Builder::new().build(&mut i2c)?; let rh = hts221.humidity_x2(&mut i2c)?; let deg_c = hts221.temperature_x8(&mut i2c)?; println!("rH = {}%", rh as f32 / 2.0); println!("Temp = {} deg C", deg_c as f32 / 8.0); ``` # License Licensed under either of - Apache License, Version 2.0 ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) - MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option. ## Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
