VCNL4010 Proximity/Light sensor - (AD18300)

Description:

The VCNL4010 sensor is an excellent choice for incorporating a short-distance proximity sensor into your microcontroller project. For longer distances (in the cm range), you can use a SHARP IR distance sensor, but these are only useful if the object is more than 10 cm away. The VCNL4010 is designed for much shorter distances, no more than 200 mm (about 7.5"), and in our experimentation, we found it worked best at distances of about 10-150 mm. It would be useful, for example, to detect when a hand moves nearby or before a robot crashes into a wall. The sensor also incorporates an ambient light sensor.

This sensor is easy to use with any I2C-enabled microcontroller. It's 5-volt compatible, so you can use it with either 3.3V or 5V logic without risk of damage. It features a built-in 3.3V ultra-low-dropout regulator, allowing it to be powered from 3.3V to 5.0V. However, if you can supply it with 5.0V, that's ideal, as the VIN voltage powers the IR LED, and the higher the voltage, the better. The more you use it, the more powerful it will be.
