This example can be used on the Pysense and Pysense 2.0 X
The Pysense has a variety of sensors available:

Pybytes is an online IoT platform, where you can receive data from your sensors and visualize it over time. To forward generated sensor data to Pybytes, you’ll first have to provision your device to Pybytes, and have it activated on boot. Then, you can use the following example to send the light sensor data to Pybytes:
import time
import pycom
import machine
from LTR329ALS01 import LTR329ALS01
sleeptime = 60*1000 # 1 minute
pycom.heartbeat(False)
pycom.rgbled(0x0A0A08) # white
py = Pycoproc()
li = LTR329ALS01(py)
light = li.light();
print("Light (channel Blue lux, channel Red lux): " + str(light))
pybytes.send_signal(0, light[0]) # channel Blue
pybytes.send_signal(1, light[1]) # channel Red
time.sleep(2) # we need to sleep to make sure the signal gets sent
machine.deepsleep(sleeptime)
