Light Sensitive Photo Resistor
$0.54The Light Sensitive Photo Resistor, also known as a photoresistor or light-dependent resistor (LDR), is a passive electronic component that changes its resistance based on the amount of light that falls on it. Photo resistors are used in a variety of applications, including light-activated switches, automatic street lights, and light-sensitive security systems. The photoresistor is made of a material that changes its electrical resistance when exposed to light. When the photoresistor is in the dark, its resistance is high, and when it is exposed to light, its resistance decreases. This change in resistance can be used to control the flow of current in a circuit, allowing for the detection of light levels and the control of light-activated devices.

Raspberry Pi NoIR Camera Board – Infrared-sensitive Camera
$39.96This 5mp IR (Infrared) camera module is capable of 1080p video and still images and connects directly to your Raspberry Pi. Similar to the non-IR version Raspberry Pi Camera, connect the included ribbon cable to the CSI (Camera Serial Interface) port on your Raspberry Pi, boot up the latest version of Raspbian and you are good to go!
At 25mm x 20mm x 9mm and weighing a little over 3 grams this board is pretty small which makes it perfect for mobile or other small applications that require you to see in near dark. The sensor has a native resolution of 5 megapixels with a fixed focus lens on board. The camera is capable of 2592 x 1944 pixel static images and also supports 1080p30, 720p60 and 640x480p60/90 video.
