Proximity Sensor Breakout - 20cm, VCNL4040 (Qwiic) (SEN-15177)

The SparkFun Proximity Sensor Breakout is a simple IR presence and ambient light sensor utilising the VCNL4040. This type of sensor is often seen in automatic towel and soap dispensers or automatic faucets. With the ability to detect objects qualitatively up to 20cm away, you will be able to detect if something is there and if it is closer or further away since the last reading. Utilising the handy Qwiic system, no soldering is required to connect it to the rest of your system. However, there are still broken out 0.1"-spaced pins in case you prefer to use a breadboard.

The SparkFun Proximity Sensor Breakout is a great digital alternative to the popular analogue based Sharp sensors. The VCNL4040 has no dead zone and can read all the way up to the face of the sensor. This sensor also has an ambient light sensor built into it which is excellent if you need a digital light sensor for your next glitter cannon.
