LTR-559 Light and Proximity Sensor

LTR-559 Light and Proximity Sensor Breakout

This LTR-559 sensor detects light over a broad dynamic range (0.01 lux to 64,000 lux) and proximity in a range of ~5cm.

The Light and Proximity Sensor is the same kind of sensor of your smartphone that determines if your phone is close to your ear and if it would be better to switch off the touchscreen.

If you want to implement an automatic and manual nightlight switch, this sensor is perfect. It can determine when light drops below a desired level and can automatically activate something like Unicorn pHAT to come on. Besides, thanks to this proximity sensor, by simply waving your hand over it, you can manually turn the light on or off.

This Breakout has an I2C interface and is 3.3V or 5V compatible. As it happens with other breakouts, the design of the Light and Proximity Sensor allows you to solder onto it a piece of right-angle header and then slide it onto the 5 pins (pins 1, 3, 5, 7, 9) on the bottom left of your Raspberry Pi’s GPIO header.

Here’s a project idea: combine this sensor with the Breakout Garden by simply sliding your breakout into one of its six slots.
