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)
