AtariLab is a sensor kit for the 8-bit Atari computers. I ordered two of the kits recently, the starter kit and the light kit, and they both arrived in pristine condition. They work great with the Atari 130XE, but the light sensor was giving me some random readings (replacing the photoresistor in that wouldn’t be hard).
The breakout board attaches to the second joystick port, and can read sensors as well as provide power:

The AtariLab includes a booklet full of experiments, and includes instructions for reading the sensors from BASIC and LOGO:
