GP2Y0A41SK0F

General description

GP2Y0A41SK0F is a distance measuring sensor unit,composed of an integrated combination of PSD(position sensitive detector) , IR-LED (infrared emitting diode) and signal processing circuit.The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor.

Feature

Distance measuring sensor is united with PSD,infrared LED and signal processing circuit
Short measuring cycle (16.5ms)
Distance measuring range : 4 to 30 cm
Compact size (29.5 × 13.0 × 13.5mm)
Analog output type

Application

Touch-less switch
Robot cleaner
Sensor for energy saving
Amusement equipment

etCMD
eCMD_START

Feature :
Command to start AD conversion.

Process :
1. AD conversion start.

Command API function :
etSTS oGP2Y0A41SK0F_START( void )

Return value :
eSTS_FIN
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT

NOTE :
Arduino, Mbeb, ModusToolbox not supported.

eCMD_READ

Feature :
Command that reads the AD conversion value, converts the AD conversion value to a characteristic Distance, and stores the Distance in rlt.

Process :
1. Read AD conversion value.
2. Convert AD conversion value to Distance.
Voltage value = (AD conversion value × VDD) / ( 2^{AD bit} )
Distance = ((voltage value – voltage offset value) / gain) + Distance offset value (Min, Max Limit)
3. Store Distance to rlt.

Command API function :
etSTS oGP2Y0A41SK0F_READ( float32* rlt )

Return value :
eSTS_FIN
eSTS_ERR_MIN
eSTS_ERR_MAX
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT

NOTE :
Please execute this API function after starting AD conversion.
Arduino, Mbeb, ModusToolbox not supported.

eCMD_START_READ

Feature :
Command that starts AD conversion, waits for AD conversion to finish, reads out the AD conversion value, converts the AD conversion value to a characteristic Distance, and stores the Distance in rlt.

Process :
1. AD conversion start.
2. Wait until AD conversion is completed.
3. Read AD conversion value.
4. Convert AD conversion value to Distance.
Voltage value = (AD conversion value × VDD) / ( 2^{AD bit} )
Distance = ((voltage value – voltage offset value) / gain) + Distance offset value (Min, Max Limit)
5. Store Distance to rlt.

Command API function :
etSTS oGP2Y0A41SK0F_START_READ( float32* rlt )

Return value :
eSTS_FIN
eSTS_ERR_MIN
eSTS_ERR_MAX
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT
