We have some in stock and you can get from here. So we did some tests on this module, as following.
Frist, connected with arduino mainboard, there are just 3 pins on DYP-ME003. You can connect ECHO（output signal）with any digital pin on mainboard, and read the value of this pin, if any people moved in the front , it will return HIGH value.
Ok，let us see some features about the module, specification here.
As the specification shows, the maximum detection range is 7 meter and the minimum delay time is 5 seconds. So, we actually test it in default status. Finally, the maximum detection range is 3.5 meters.We adjust tag 2 potentiometer（as the following picture shows）clockwise, detection range up to 7 meters. The other potentiometer tag 1(as the following picture shows) is used to adjust delay time for ECHO high duration, the minimum duration is about 4~5s and maximum duration is about 300s which match to specifications.
Tag 1: Delay Time potentiometer Tag 2:Distance potentiometer Tag 3: Trigger mode jumping
The photosensitive control, I think it not widely use, we test the module both the day and night. We find the influence of light is not very clear.
Twice trigger mode, this very interesting. once trigger mode couldn’t repeat the trigger, the another could repeatable trigger,you can select by tag 3 jumping.
These modes should satisfy the most people ‘s needs .
We think that you can use it to make something very interesting. All in all, this DYP-ME003 module is recommended, as its performance and price.
