Function Documentation

int atlas_sensor_calibrate

(

uint8

sensor_address

)

Calibrate Atlas sensor using single-point method.

Parameters

sensor_address

I2C slave address of sensor

Returns

1 on success

int atlas_sensor_sleep

(

uint8

sensor_address

)

Put Atlas I2C sensor into sleep mode.

Parameters

sensor_address

I2C slave address of sensor

Returns

1 on success

uint8 atlas_take_con_reading

(

con_reading *

reading

)

Take a single reading from Atlas sensor in I2C mode. Used for conductivity sensor.

Parameters

reading

Struct for conductivity reading (to be written to)

Returns

1u on success, and 0u otherwise.

Here is the caller graph for this function:

uint8 atlas_take_single_reading	(	uint8	sensor_address,
		float *	reading
	)

Take a single reading from Atlas sensor in I2C mode. Used for Temperature, DO, ORP and PH.

Parameters

sensor_address	I2C slave address of sensor
reading	Value of reading (to be written to)

Returns

1u on success, and 0u otherwise.

Here is the caller graph for this function:

uint8 zip_atlas_wq	(	char *	labels[],
		float	readings[],
		uint8 *	array_ix,
		uint8	max_size
	)

Inserts current values of water quality measurements into labels and readings arrays.

Parameters

labels	Array to store labels corresponding to each sensor reading
readings	Array to store sensor readings as floating point values
array_ix	Array index to label and readings
max_size	Maximum size of label and reading arrays (number of entries)

Returns

(*array_ix) + number of entries filled
