AM2315 by Measurement Specialties (http://www.aosong.com/asp_bin/Products/en/AM2315.pdf) is a digital humidity sensor with temperature output. RH reports between 0 and 100%, and the temperature range is -40 to +125 degC. The sampling period of this sensor is 2 seconds. Reads occurring more often than that return cached data.

Constructor & Destructor Documentation

AM2315	(	int	bus,
		int	devAddr
	)

Instantiates an AM2315 object

Parameters

bus	Number of the used bus
devAddr	Address of the used I2C device
mode	AM2315 oversampling

Member Function Documentation

int i2cReadReg_16

(

int

reg

)

Reads a two-byte register

Parameters

reg	Address of the register

long i2cReadReg_32

(

int

reg

)

Reads a four-byte register

Parameters

reg	Address of the register

short i2cReadReg_8

(

int

reg

)

Reads a one-byte register

Parameters

reg	Address of the register

int i2cWriteReg_16	(	int	reg,
		int	ival
	)

Writes a two-byte (16b) register

Parameters

reg	Address of the register
ival	16b value

int i2cWriteReg_32	(	int	reg,
		long	ival
	)

Writes a four-byte (32b) register

Note: these access routines are not the normal accesses to an I2C device. AM2315 contains a microcontroller that manages the actual readings. These handlers then make requests over I2C using a protocol defined by AM2315.

Parameters

reg	Address of the register
ival	32b value

int i2cWriteReg_8	(	int	reg,
		short	ival
	)

Writes a one-byte (8b) register

Parameters

reg	Address of the register
ival	8b value
