| - | ===== IR-Sensitive Camera Modules ===== | ||
| - | |||
| - | Standard cameras block infrared light to mimic human vision. For this project, you must use a **NoIR** (No Infrared) sensor. These sensors are wide-open to the 850nm spectrum, allowing your flashlight to act like a massive invisible floodlight. | ||
