BOOSTXL-TLV8544PIR: what is the difference between ready PIR module(digital output HIGH/LOW) like (penasonic,parallax) and TLV8455PIR.

Part Number:BOOSTXL-TLV8544PIR

Hello,

1) is there any difference between PIR module(digital output HIGH/LOW) like (penasonic,parallax) and TLV8544PIR?

2) is it possible to detect stationary human using TLV8544PIR with some software algorithms?

3) what is the purpose of giving analog output of each stage along with digital output? 

4) how to use this device for best performance?

Regards
