3595-ADA Adafruit APDS9960 Proximity, Light, RGB, and Gesture Sensor
US$11.95
Add basic gesture sensing, RGB color sensing, proximity sensing, or ambient light sensing to your project with the Adafruit APDS9960 Proximity, Light, RGB and Gesture Sensor. When connected to your microcontroller (running our library code) it can detect simple gestures (left to right, right to left, up to down, down to up are currently supported), return the amount of red, blue, green, and clear light, or return how close an object is to the front of the sensor. This device uses an I2C interface so it's easy to wire up and use. The APDS9960 from Avago Technologies has an integrated IR LED and driver, along with four directional photodiodes that sense reflected IR energy from the LED. It's proximity detection feature allows it to measure the distance an object is from the front of the sensor (up to a few centimeters) with 8 bit resolution.

164-ADA IR distance sensor includes cable (10cm-80cm) - GP2Y0A21YK0F
164-ADA IR distance sensor includes cable (10cm-80cm) - GP2Y0A21YK0F
US$26.17
This SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine how close the nearest object is. Comes with 12" long 3-JST interface wire. These sensors are good for short-range detection. For over 1 m distance, we suggest using sonar sensors.
