I have just received the PIR2 sensors and I have started playing with them.
At first glance, it seems they are working fine but I have a problem with the sensor sensibility.
The problem is that the sensor detects very hard objects that are located on more than 3 meters.
For example, when my kids are running around the sensor (>3 and <5 meters) it does not detect them (very rarely it detects that something is happening).
I guess that pets detection is something that makes the sensor not so sensitive and I was wondering if somehow I can adjust the sensitivity of the sensor. I saw that the sensor has modes (Full, Norm, Code, Puls1, Pusl2 and Puls3) but I am not sure what do they do. I also noticed that the old versions of the sensors have had jumpers but mine has only a place ready for jumpers.
Can you tell me if there is a way I can increase the sensitivity of the sensor as in the current state it is almost useless?
Thanks in advance.
I have the same question. Just blank solder joints. Are they not adjustable like other boards (broadlink)?
Can I solder a wire across?
