Adafruit_ADS1X15 | bit Differential or Single-Ended ADC

I had write a code to measure the conductivity and flow with the help of sensors interfaced with raspberry pi and display and update the value on tkinter gui every 5 secs.

I am getting error due to import board and GPIO.setmode(GPIO.BOARD) used in same program.The exact error i am getting is "Another mode for Board is already set" help me to solve this error.

I recently started a project to make a data logging script for my Raspberry Pi. My goal is to make a program that can:

1. Collect voltage data from the pH sensor that's hooked up to my Pi (that's the getData() function).
2. Plot it on the screen in real time.
3. Continuously append them into a CSV file every few seconds.

I've included my code below for both the function that collects sensor data and the function that plots/saves them. Everything works as expected, except for some reason I can't see the new data added to the CSV file test2.csv until I terminate the code with Ctrl+C (the IDE is Thonny).

While the code is running, the csv file is just blank, and not even the heading "Data and Time, P0, P1" is there, making me think that for some reason Python doesn't actually append new data into the file until the very end.

If I stopped the script using the red "Stop/Restart Backend" button from Thonny, no new data will be added to test2.csv. New data will only be appended to test2.csv if I run the script and stop it using Ctrl+C, which isn't helpful because I want to be able to access the existing data without stopping the program.

Any idea on how to fix this so that the CSV file will update without me terminating the script?

My function for collecting data:

I'm trying to display the values obtained from my heartbeat sensor in my Kivy App. I've tried using the data extraction method applied on the other sensors but it's not working for this sensor as it doesn't contain any functions.

I've tried multiple different approaches but they all haven't returned the desired output. Can someone please have a look at the sensor code and suggest some method to display the output in my kivy app.

So I have developed a code which will detect a voltage off a transducer and then output an average voltage, my question here is how can I get this value to update as my sensor value changes, currently it is prinitng the initial value and then not updating, I created a mainwindow using QTDesigner, and I am using Python3 and PyQt5 library to write the code.

is this even possible? if so how?

This is my code:

I have devised a circuit in which I am getting a pressure reading from a Dwyer 616kd-11-v Transducer with a Range of 0-500Pa, I am powering this with a 5v Power Supply and it shares a common ground to the Raspberry Pi. My ADC converter is a 16 Bit ADS1115 By Texas Instruments. I have connected the transducer and I am getting a reading which is similar to that I am getting on another External Airflow Pressure meter.

The problem is as soon as the Pressure reaches 324Pa or more the Reading in my Python Shell freezes at 324 and does not change until the value has dropped below 324Pa. The Transducer has a range of upto 500Pa meaning it should be able to read upto this value?

I will attach the code I use for this below and will include my basic circuit connections.

Full Code:

I'm having an issue with my code. I'm trying to read voltage measurements from my ADC and get the average of every 100 readings then display the average on my default screen. The process is supposed to repeat and the label should be updating every 0.5 seconds. However, my label doesn't even show on the screen.

These are some snippets of my code

I am getting this error: 'int' object is not iterable for the following codes which is meant for sending sensor values from my Raspberry Pi to Ubidots. I have read similar questions and answers but I cannot figure out where the error lies.

I have connected a soil moisture sensor module and an LDR to an ADS1115 ADC (which is in turn connected to my R Pi). Am using Python 2.7. The ADC works fine and it prints values from channel 0 and channel 1 for the soil moisture module and the LDR respectively. I have the following codes to send data from the soil moisture module to Thingspeak using the following guides: https://www.mathworks.com/help/thingspeak/use-raspberry-pi-board-that-runs-python-websockets-to-publish-to-a-channel.html
