[−][src]Crate bme280
A platform agnostic Rust driver for the Bosch BME280 and BMP280, based on the
embedded-hal
traits.
The Device
The Bosch BME280 is a highly accurate sensor for atmospheric temperature, pressure, and relative humidity.
The Bosch BMP280 is a highly accurate sensor for atmospheric temperature, and pressure.
The device has I²C and SPI interfaces (SPI is not currently supported).
Usage
extern crate linux_embedded_hal as hal; extern crate bme280; use hal::{Delay, I2cdev}; use bme280::BME280; // using Linux I2C Bus #1 in this example let i2c_bus = I2cdev::new("/dev/i2c-1").unwrap(); // initialize the BME280 using the primary I2C address 0x76 let mut bme280 = BME280::new_primary(i2c_bus, Delay); // or, initialize the BME280 using the secondary I2C address 0x77 // let mut bme280 = BME280::new_secondary(i2c_bus, Delay); // or, initialize the BME280 using a custom I2C address // let bme280_i2c_addr = 0x88; // let mut bme280 = BME280::new(i2c_bus, bme280_i2c_addr, Delay); // initialize the sensor bme280.init().unwrap(); // measure temperature, pressure, and humidity let measurements = bme280.measure().unwrap(); println!("Relative Humidity = {}%", measurements.humidity); println!("Temperature = {} deg C", measurements.temperature); println!("Pressure = {} pascals", measurements.pressure);
