SKU: AF-5378

The Adafruit Right Angle VEML7700 Lux Sensor is an I2C ambient light sensor that measures calibrated lux values rather than arbitrary brightness numbers. Its unique right-angle orientation senses light coming parallel to the PCB surface rather than perpendicular — ideal for edge-lit enclosures an...

SKU: AF-5396

The Adafruit VL53L4CD is a Time-of-Flight (ToF) distance sensor from ST that combines short-range and medium-range sensing in one chip. It measures from approximately 1 mm right up to 1300 mm, bridging the gap between the close-range VL6180X and the longer-range VL53L0X — all using an invisible l...

SKU: AF-5425

The Adafruit VL53L4CX is the longest-range Time-of-Flight (ToF) distance sensor in ST's VL5 series, measuring from approximately 1 mm up to 6000 mm (6 metres). It uses an invisible laser to precisely time how long light takes to bounce back, delivering accurate distance readings without the linea...
