Wemos D1
The Wemos D1 looks like the normal Arduino board with the same pin layout as the Uno, which means all of the shields which can be used with the Arduino Uno, will plug in seamlessly with the Wemos D1. While the connection is one thing, the shields must have matching libraries that work with the esp8266 platform so as to be able to establish easy communication between the Wemos and the shield.
Crowtail- PIR Motion Sensor 2.0
This is a simple to use PIR motion sensor with Crowtail compatible interface. Simply connect it to Crowtail base shield and program it, when anyone moves in its detecting range, the sensor outputs HIGH on its SIG pin. The detecting range can be adjusted by a potentiometer soldered on its circuit board, The max detecting range of it up to 6 meters.
