Parameters
Parameters 
Description 
M32 * pDeviceResponse = NULL 
(see Message) 
void * pReserved = NULL 
(see Message) 
Returns

The sensor distance measurement, 0 if an error occurred.

Description

GetMeasure gets the distance measurement of the sensor, in meter. If the sensor 'see' nothing, measurement is equal to the maximum detection distance. The returned value, if valid, is the latest known value. Consecutive calls to GetMeasure faster than the device refresh rate may return the same value. 

 

 

Notes

Caution: measurement 0 can mean OR NOT that error it occurred. It is required to use pDeviceResponse to make the difference between an error and a true 0 measurement.
