Pressure monitor for keg fridge

[Larz60+]

One thing that I would do is create a timer event, rather than poll time.
This will free up the processor so other things can be done (if needed) while waiting for an event.

Try running this snippet:

example using threaded timer:

import time, threading


def threaded_timer(delay=1):
    print(f"In timer loop: {time.ctime()}")
    threading.Timer(delay, threaded_timer).start()

# wake up after 6 seconds (can use decimal here for times less than 1 sec)
threaded_timer(delay=4)

print('Do something while waiting for timer')
time.sleep(1)
print('Do something else while waiting for timer')

Notice that timer runs independently from other code.

Output:
In timer loop: Wed Dec  2 06:42:13 2020
Do something while waiting for timer
Do something else while waiting for timer
In timer loop: Wed Dec  2 06:42:17 2020
In timer loop: Wed Dec  2 06:42:18 2020
In timer loop: Wed Dec  2 06:42:19 2020
