Another APDS9960 / GY-9960LLC / APDS9900 micro python library optimized for ESP8266 / ESP12-E for:
* Light Sensing (Ambient Light and RGB Color Sensing)
* Proximity Sensing
Documentation
=============
Complete documentation is hosted on the "Read the Docs" page
`upy-apds9960.readthedocs.io `_
Dependencies
============
This driver depends on:
* `MicroPython `_
Tested on:
| Sensor: `GY-9960LLC `_
| Sensor: `APDS-9900 `_
| Devboard: Node MCU v1.0 & Raspberry PI Pico
Installation
============
* Flash the device with MicroPython
* Copy the folder uPy_APDS9960 and content (apds9960LITE.py) to the root folder for APDS9960 circuits
* Copy the folder uPy_APDS9900 and content (apds9900LITE.py) to the root folder for APDS9900 circuits
The steps above is descsribed in the `Thonny IDE tutorial`_.
.. _Thonny IDE tutorial: https://upy-apds9960.readthedocs.io/en/latest/thonny_guide.html
Examples
========
The examples in theis respository uses the NodeMCU devboard the devboard to use rpi pico please change the I2C inferface as show in the code below
.. code-block:: python
#Change I2C interface from:
# i2c = machine.I2C(scl=machine.Pin(5), sda=machine.Pin(4))
#to:
i2c = machine.I2C(0,scl=machine.Pin(17), sda=machine.Pin(16))
Here is the `NodeMCU Hookup`_.
.. _NodeMCU Hookup: ./node_mcu_example.rst
APDS9960 Example
================
.. code-block:: python
import machine
from time import sleep_ms
from uPy_APDS9960.apds9960LITE import APDS9960LITE
#Init I2C Buss on RP2040
i2c = machine.I2C(0,scl=machine.Pin(17), sda=machine.Pin(16))
apds9960=APDS9960LITE(i2c) # Enable sensor
apds9960.prox.enableSensor() # Enable Proximit sensing
while True:
sleep_ms(25) # wait for readout to be ready
print(apds9960.prox.proximityLevel) #Print the proximity value
APDS9900 Example
================
.. code-block:: python
import machine
from time import sleep_ms
from uPy_APDS9900.apds9900LITE import APDS9900LITE
#Init I2C Buss on RP2040
i2c = machine.I2C(0,scl=machine.Pin(17), sda=machine.Pin(16))
apds9900=APDS9900LITE(i2c) # Enable sensor
apds9900.prox.enableSensor() # Enable Proximit sensing
while True:
sleep_ms(25) # wait for readout to be ready
print(apds9900.prox.proximityLevel) #Print the proximity value
Hardware Set-up
---------------
Connect Vin to 3.3 V or 5 V power source, GND to ground, SCL and SDA to the appropriate pins to the Raspberry PI Pico

Basics
------
Of course, you must import the device and library :)
.. code:: python
import machine
from time import sleep_ms
from uPy_APDS9960.apds9960LITE import APDS9960LITE
To set-up the device to gather data, initialize the I2C-device using SCL and SDA pins.
Then initialize the library.
.. code:: python
i2c = machine.I2C(0,scl=machine.Pin(17), sda=machine.Pin(16))
apds9960=APDS9960LITE(i2c) # Poweron APDS9960
Proximity
~~~~~~~~~
Proximity funxtionalites is accessed torough the apds9960.prox member :class:`.PROX`
.. code:: python
apds9960.prox.enableSensor() # Enable Proximity sensing
sleep_ms(25) # wait for readout to be ready
print(apds9960.prox.proximityLevel) # Print the proximity value
Light Sensing
~~~~~~~~~~~~~
Proximity funxtionalites is accessed torough the apds9960.als member :class:`.ALS`
.. code:: python
apds9960.als.enableSensor() # Enable Light sensor
sleep_ms(25) # Wait for readout to be ready
print(apds9960.als.ambientLightLevel) # Print the ambient light value
Debug
-----
If things does not work try to run the script below to verify that it i2c communication with the apds9960 is working as expected
.. code:: python
import machine
i2c = machine.I2C(0,scl=machine.Pin(17), sda=machine.Pin(16))
print('Scan i2c bus...')
devices = i2c.scan()
if len(devices) == 0:
print("No i2c device !")
else:
print('i2c devices found:',len(devices))
for device in devices:
print("Decimal address: ",device," | Hexa address: ",hex(device))
if(device==0x39): # APDS9960 Address = 0x39
deviceID=i2c.readfrom_mem(devices[0],0x92, 1) #Get deviceID
deviceID=int.from_bytes(deviceID,'big') #Conv byte to int
if(deviceID==0x29):
deviceID=9900
elif(deviceID==0x20):
deviceID=9901
else:
deviceID=9960
print("Found ADPS-",deviceID)
If successful the output should be:
.. code-block:: shell
Scan i2c bus...
i2c devices found: 1
Decimal address: 57 | Hexa address: 0x39
Found ADPS- 9960
.. note:: Be aware if the output shows: ::
"many i2c devices was listed" check if the i2c pins are allocated correctly
"No i2c device" check if the power is correctly connected
The Device id can be 0xa8, 0xab 0x9c or 0x55.)
