Struct SysfsSensor 

pub struct SysfsSensor { /* private fields */ }

Sensor that reads a single value from a /sys filesystem path.

Common uses:

• /sys/class/thermal/thermal_zone0/temp (temperature in millidegrees)
• /sys/class/hwmon/hwmon0/fan1_input (fan RPM)
• /sys/class/power_supply/BAT0/capacity (battery percentage)

The scale field divides the raw integer value (e.g., 55000 → 55.0 for millidegrees → degrees).

Implementations

impl SysfsSensor

pub fn new( id: impl Into<String>, kind: SensorKind, path: impl Into<String>, scale: f64, ) -> Self

Create a new sysfs sensor.

• path: absolute path to the sysfs file (e.g., /sys/class/thermal/thermal_zone0/temp)
• scale: divisor to convert raw integer to float (e.g., 1000.0 for millidegrees)

pub fn thermal(zone: usize) -> Self

Create a thermal zone sensor (temperature in °C).

pub fn battery(name: &str) -> Self

Create a battery capacity sensor (0.0–100.0).

pub fn fan(hwmon: usize, fan: usize) -> Self

Create a fan speed sensor (RPM).

Trait Implementations

impl Debug for SysfsSensor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl SensorDevice for SysfsSensor

fn id(&self) -> &str

Unique sensor identifier.

fn kind(&self) -> SensorKind

Sensor type.

fn read(&self) -> Option<SensorReading>

Read current value. Returns None if the sensor is unavailable.

fn is_available(&self) -> bool

Whether the sensor is currently available/connected.
