Possible causes of no output from SPAD sensor

As the first time I used a SPAD sensor, I didn't get the correct output from my SPAD sensor for two reasons:

Reason 1:


The enable terminal is not connected high level voltage. The SPAD sensor is likely to have an enable terminal. Only when the enable terminal is connected to a high level can data be collected normally.

Reason 2:


The protective head of the SPAD sensor has not been removed. In order to protect the sensor, SPAD sensors usually have a protective cover. Data can only be obtained if the black protective cover is removed.

Summary:


The above reasons are generally explained in the manual. Reading the manual carefully before the first use can avoid many common mistakes.
