Hi, I came across your job posting seeking an experienced programmer to refine the code for reading 4-20mA analog signals on your ESP32 WROOM board with ADS1115 over i2c. As a seasoned programmer with over 3 years of experience in IoT technologies and analog-to-digital conversions, I am confident I can tackle the challenges you're facing with signal fluctuation. Understanding the Problem: You've already made significant progress with your project—you've built the board, written code for reading, and even implemented some statistical tools like averaging and RMS calculations. However, the still-erratic signal behavior suggests that further fine-tuning is necessary for stable and reliable readings. My Solution: Review Current Code: To understand why the signals are fluctuating, I'll first dive into your existing code. Optimize Signal Processing Algorithms: I can enhance your current Int[] readings by integrating advanced filtering algorithms, possibly leveraging Kalman or Particle filters. Precision Tuning: For calculating the RMS value and applying rolling averages, I'll ensure the precision is up to industry standards to minimize signal noise. Code Documentation & Testing: I'll document each code change and validate the performance through rigorous testing.

Dear Sir , I would be glad to challenge your project. I analyse your photo included with photoshop it's not a program issue , it's a hardware issue. As I have a good experience in prossessing data by sensors over the air and wired . I have determine what is the problem with your PCB . Feel free to contact me in orther to see what kind of sensor are you using and what kind of dc sources are you scaling.
