Pololu 38 kHz IR Proximity Sensor, Fixed Gain, Low Brightness Hand These sensors are often used

These sensors are often used in applications with long wires where a voltage signal would normally drop off due to line resistance and be susceptible to interference

making them an excellent choice for beginners looking to get started with open-source hardware

FAULT Open-drain output that drives low when an over-current

5 RC (digital) 30 mA 220 mA 5 mm This array of IR LED/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection)

Pololu 38 kHz IR Proximity Sensor, Fixed Gain, Low Brightness Hand These sensors are often usedThis module features a fixed gain, 38 kHz modulated IR sensor and a corresponding IR LED with oscillator circuit to make a tiny proximity sensor. This low brightness version draws an average of 8 mA at 5 V and has a typical sensing range up to approximately 12 inches (30 cm) . Overview These sensor modules are based on Vishay's TSSP77038 modulated infrared receivers. Most IR receiver modules designed for remote control of appliances like televisions,
