Rated 4.6 out of 5 stars.
Need a simple IR sensor for your electronics project? These QRE1113 modules are a popular choice. They work on 3.3V to 5V DC, draw about 25mA, and have an optimal sensing distance of around 3mm. They use an infrared LED and receiver to detect reflected light—great for line following, obstacle avoidance, proximity sensing, or surface brightness detection. The brighter the surface, the faster the output changes. Each module is tiny (roughly 14.5x8mm), so they're easy to mount on robots, cars, or custom circuits. You get 4 modules in the pack, which is handy for prototyping or multi-sensor setups. No fancy extras, just reliable, basic IR sensing. Perfect for Arduino, Raspberry Pi, or other microcontroller projects.
