Light, Temperature, Humidity and Motion Sensor.

Light Sensor, connected to Analog pin, I used one like this:- https://www.ebay.co.uk/itm/LDR-Photoresistor-Light-Detection-Sensor-Module-Dependent-Resistor-Arduino-PIC/274289838944?hash=item3fdcf2cb60:g:ArUAAOSwGyleWUjE

LED on GPIO 13 with a suitable resistor dependant on your LED

Motion sensor HC-SR501 on GPIO 5

Temperature sensor DHT22 on GPIO 4
