Implementations

impl PhSensor

pub fn new() -> Self

pub fn new_alt_addr() -> Self

Create a new sensor with an ADC I2C address of 0x49.

pub fn cal_nitrate_default(&mut self)

Set calibration to a sensible default for nitrate, with unit mg/L

pub fn cal_phosphate_default(&mut self)

Set calibration to a sensible default for phosphate, with unit mg/L

pub fn cal_potassium_default(&mut self)

Set calibration to a sensible default for potassium, with unit mg/L

pub fn read<I2C, E>(&mut self, t: TempSource, i2c: &mut I2C) -> f32 where
    I2C: Write<Error = E> + WriteRead<Error = E>, 

Take a pH reading

pub fn read_voltage<I2C, E>(&mut self, i2c: &mut I2C) -> f32 where
    I2C: Write<Error = E> + WriteRead<Error = E>, 

Useful for getting calibration data

pub fn read_temp<I2C, E>(&mut self, i2c: &mut I2C) -> f32 where
    I2C: Write<Error = E> + WriteRead<Error = E>, 

Useful for getting calibration data

pub fn calibrate<I2C, E>(
    &mut self,
    slot: CalSlot,
    pH: f32,
    t: TempSource,
    i2c: &mut I2C
) -> (f32, f32) where
    I2C: Write<Error = E> + WriteRead<Error = E>, 

Calibrate by measuring voltage and temp at a given pH. Set the calibration, and return (Voltage, Temp).

pub fn calibrate_all(&mut self, pt0: CalPt, pt1: CalPt, pt2: Option<CalPt>)

pub fn reset_calibration(&mut self)
