APDS-9960 Light Sensor
This documentation includes installation guidelines and sample code for your hardware.
Turta_APDS9960 library is responsible for communicating with the APDS-9960 sensor.
To install the library from the (PyPI) Python Package Index, enter the following command to the console.
pip install turta-iothat
Add the following statement to the top of your Python code.
from turta_iothat import Turta_APDS9960
Then, create an instance of the Turta_APDS9960 class.
apds9960 = Turta_APDS9960.APDS9960Sensor()
Now you're ready to access the library by calling the apds9960 instance.
The library automatically initializes the required components when its instance is being created, so there is no need to do a manual initialization.
Reads the ambient light value.
int read_ambient_light()
Reads the RGB light values.
int[] read_rgb_light()
Reads the proximity value.
int read_proximity()
Toggles the sensor modes.
set_mode(ambient_and_rgb_light_enabled, proximity_detection_enabled, gesture_recognition_enabled):
You can copy the example code from https://github.com/Turta-io/IoTHAT/tree/master/Samples/Raspbian/Python address, and then copy it to the Raspberry Pi. There is one example of this library.
This application demonstrates ambient light, RGB light, and proximity readings.
To run the example:
- 1.Copy the library and sample code to a folder on the Raspberry Pi.
- 2.Open terminal, and go to the folder you copied the codes.
- 3.Run the sample with the following command:
python APDS9960SampleApp.py
Sample Code
APDS9960SampleApp.py
#! /usr/bin/python
import time
from turta_iothat import Turta_APDS9960
#Install IoT HAT library with "pip install turta-iothat"
#Initialize
apds9960 = Turta_APDS9960.APDS9960Sensor()
try:
while True:
#Read & print ambient light
print("Ambient Light...: " + str(apds9960.read_ambient_light()))
#Read & print color values
rgb = apds9960.read_rgb_light()
print("Red.............: " + str(rgb[0]))
print("Green...........: " + str(rgb[1]))
print("Blue............: " + str(rgb[2]))
#Read & print proximity
print("Proximity.......: " + str(apds9960.read_proximity()))
#Rest a bit
print("-----")
time.sleep(0.5)
#Exit on CTRL+C
except KeyboardInterrupt:
print('Bye.')
Result
When you run the sample, it prints ambient light, RGB light and proximity readings to the terminal. The example output should be like this:
Ambient Light...: 287
Red.............: 124
Green...........: 345
Blue............: 212
Proximity.......: 132
