Expand description
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.
Usage
use linux_embedded_hal::{Delay, I2cdev};
use bme280::i2c::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);Modules
