Code

main.py

Python
Create new Zerynth project and add two files: main.py and helpers.py.
Enter your Wi-Fi credentials and Unique Ubidots TOKEN where indicated
import streams
from wireless import wifi
from xinabox.sl06 import sl06

streams.serial()

# SL06 instance
SL06 = sl06.SL06(I2C0)

# choose a wifi chip supporting secure sockets
from espressif.esp32net import esp32wifi as wifi_driver
wifi_driver.auto_init()

# import ubidots iot module
from ubidots.iot import iot

# configure SL06
SL06.init()

# enable SL06 for light sensing
SL06.enableLightSensor()

print('connecting to wifi...')
 
#Connect to the specified Wi-Fi device
while not wifi.is_linked():
    try:
    # FOR THIS EXAMPLE TO WORK, "SSID" AND "PASSWORD" MUST BE SET
    # TO MATCH YOUR ACTUAL NETWORK CONFIGURATION
      wifi.link("SSID",wifi.WIFI_WPA2,"PASSWORD")
      print("Link Established")
    except Exception as e:

    print("ooops, something went wrong :(", e)
    while True:
       sleep(1000)

helpers.py

Python
Auxiliary code for Ubidots library to work
import json

    while True:
        line = confstream.readline()
