Hi! I see you need temperature-based VFD speed control, but I want to confirm your VFD's control interface before proposing a design - does it accept 0-10V analog, 4-20mA, or Modbus RTU commands? Most three-phase drives use one of these, and it completely determines the isolation circuitry we'll need. The DS18B20 sensor is solid for this application, though we'll need careful EMI filtering since VFDs generate brutal electrical noise that causes false temperature readings if not properly mitigated. I recently designed an RS485 Modbus controller for industrial pump automation using ESP32 with isolated I/O, where motor noise was corrupting sensor data until I implemented proper ground plane isolation and optocoupled interfaces. That project taught me the hard way that direct microcontroller-to-VFD connections fail spectacularly in industrial environments - electrical isolation isn't optional, it's survival. we can discuss it more in details in chat when i have the complete data. Thanks Regards

Hi brother,I’m a Elctronics Engineer with hands-on experience in embedded control and automation systems, and I can develop a system to control a three-phase VFD using a DS18B20 temperature sensor. The system will read temperature data (converted to Fahrenheit), process it in real time, and adjust the VFD speed proportionally as the temperature rises. I can design the control logic to be safe, responsive, and precise, with proper isolation and interface considerations for three-phase AC equipment. Deliverables will include: fully commented source code, wiring/control diagrams, instructions for setup and calibration, and documentation on operation and safety considerations. The system can be implemented using Arduino, ESP32, or similar microcontrollers compatible with industrial VFD interfaces. Regards Hasan

Hello, I’ll develop a control system to manage your three-phase VFD based on readings from the DS18B20 temperature sensor. The likely approach involves leveraging the sensor's data to dynamically adjust the VFD speed as temperatures rise while ensuring accurate temperature reporting in Fahrenheit. I have successfully implemented similar control systems, integrating temperature sensors with VFDs for optimized performance in industrial settings. My experience includes programming in C/C++ and Python, where I've designed reliable and responsive control algorithms. My approach will start by wiring and calibrating the DS18B20, ensuring accurate temperature readings. I’ll then create a control loop to adjust the VFD speed proportionally to temperature changes. This will involve configuring the VFD parameters for smooth operation and stability. To tailor the solution to your needs, could you clarify: 1. What specific range of temperature adjustments do you anticipate for the VFD speed? 2. Are there any safety limits or thresholds you want to implement for the VFD operation? I’m ready to start immediately and ensure your system functions efficiently and reliably. Let’s get this project underway.

Hi, that’s great to hear! Your project closely aligns with one I recently completed. In that project, I built a temperature‑driven motor control system using DS18B20 sensors, PWM motor drivers, and embedded C with microcontroller-based automation, control logic, and real‑time feedback integration. Your goal of adjusting a three-phase VFD according to rising temperature in Fahrenheit fits perfectly with my expertise, especially in sensor calibration, closed‑loop control, and safe VFD interfacing. This type of system requires stable 1-Wire communication with the DS18B20, precise scaling of Fahrenheit output, and a carefully designed control curve to ramp the VFD speed proportionally. I can deliver a clean and reliable solution tailored to your hardware. I’d be glad to connect and share my experience in more detail over chat. Thank you. Best regards, Lazar

Hey there, What VFD model/control input are you using - 0–10V analog, 4–20mA, or Modbus (RS485) - so the temperature-to-speed control maps correctly? Recently, I built a temperature-based speed control for an industrial fan where the key challenge was stable ramping (no hunting) - I solved it with a simple control curve, filtering, and safety limits for min/max frequency. For this project, I will first read the DS18B20 reliably, convert to Fahrenheit, and implement a configurable temp -> VFD speed curve with smooth ramping and safe limits. Just wondering, what temperature range should correspond to min/max VFD speed, and do you need fail-safe behavior if the sensor disconnects? Hope to discuss more on chat Best Maksym

Hello, no problem. I am a controls engineer with extensive experience in integrating temperature sensors with VFDs for automated process control. I will design a system that reads data from your DS18B20 temperature sensor (in Fahrenheit) and uses a microcontroller (such as an Arduino or PLC) to output an analog control signal (0-10V or 4-20mA) to your three-phase VFD, proportionally increasing the drive speed as the temperature rises. I can provide the complete schematic, programming code, and wiring diagram. I am ready to begin as soon as you share the VFD model and control signal requirements. Sincerely, Lorenzo

Hey there, What VFD model do you use and what control input do you want: 0–10V, 4–20mA, Modbus RTU, or digital start/stop only? What temperature range maps to what speed, and do you need a minimum speed, max speed, and a safe over-temp shutdown? I can build a simple, safe control loop: read DS18B20, convert to Fahrenheit, filter noise, then output a speed command to the VFD based on a curve you choose. I will add ramping so speed changes are smooth, plus fault handling for sensor disconnect and over-temp. Hardware can be a small MCU like ESP32 or Arduino, with proper isolation if you use analog output to the VFD. You will get firmware, wiring diagram, and a short setup guide showing how to adjust thresholds and scaling. Hope to discuss more on chat Best, Artem
