A shield is essentially a "daughterboard" of a PCB that has pins to match the female pin headers on a standard format Arduino board. You build your circuits/connections of sensors (switches, light, sound, temperature sensors, etc.) and outputs (LED's, displays, etc.) on a shield as an efficient way to mate the inputs/output connections to an Arduino board. A shield is not required but is highly advised as a way to insure solid connections and organization of connections. For more information see:
No the sensor is an LED and a photo-transistor.
LED motion sensor lights can be purchased on the Amazon website, at Lowes and its website, Sylvania Online Store, Home Depot and its website, and DHgate.
The airport code for Pulkovo Airport is LED.

i have just gone through this same situation, in my case it follows with i think 1157 or 1137 regardless they are o2 sensor codes. funny enough this , in my case, led to the MAP sensor found center rear of intake manifold. worked for me 100 CAD new pop it out and replace it should be good as new! Good luck

It depends on the wattage and how much light the LED emits. 3000K refers to the color temperature of the light and has no relationship to brightness.
no
Please unscramble your code.
Two pairs of Infrared LEDs are used as motion sensor detector. The first one is wired to emit LED and the second is wired to transmit a signal when it receives an infrared input. this infrared is reflected back to the receiving LED and then the signal is produced. This signal can be used to open sliding doors, turn on a light or set off an alarm.
