Detect motion of close-up surfaces with this Breakout Garden compatible optical navigation breakout - great for floor tracking for ground-dwelling robots!

The PAA5100JE sensor is used in robot vacuum cleaners and uses a low-resolution camera and some clever algorithms to detect motion of surfaces. This sensor has a super close range of 15-35mm so it's suitable for use with a variety of different surfaces. If you're looking for a similar sensor with a bigger range (for attaching to something like a drone) check out the PMW3901 breakout.

You can use this breakout completely solder-free with any Breakout Garden with an SPI slot, for ease of prototyping.

Python library

Software

Pimoroni has adapted the PWM3901 Python library to work with this sensor as well. It makes reading the x/y motion values and their magnitude really straightforward. Use the following line at the beginning of your code to make sure it's set up correctly:

from pmw3901 import PAA5100

Connecting to your Raspberry Pi

If you're not using a Breakout Garden, this is how to connect your Near Optical Flow Sensor Breakout up to your Raspberry Pi.

This library is set up to use the front SPI slot by default: BCM 7 for CS, BCM 11 for SCK, BCM 10 for MOSI, BCM 9 for MISO, and BCM 19 for the INT pin.

Here's which pins to connect between your Near Optical Flow Sensor Breakout and your Pi's GPIO (note that it's BCM pin numbering):

3-5V to any 5V or 3V pin
CS to BCM 7
SCK to BCM 11
MOSI to BCM 10
MISO to BCM 9
INT to BCM 19
GND to any ground pin

You can of course use other pins but you'll have to change them accordingly when you instantiate the sensor in your code.
