Change ESP32 with sensors from i2c to RS485

£18-36 GBP / hour

£18-36 GBP / hour

We have an environmental monitoring system which uses an ESP32 controller. It uses i2c protocol to talk to sensors, which is not working reliably enough in a noisy environment, so we'd like to change to RS485/MODBUS. We already have the RS485 sensors. This project is to update our main board schematic and PCB for RS485, as well as updating the firmware to use the new sensors.

How are you doing? My name is Cristian, electrical engineer with 5+ years of experience in circuit design, PCB layout and firmware programming. I had the opportunity to design various custom PCBs using ESP32 in the past. For the interfacing RS485 sensors, we might need to use MAX485 IC in the circuit design using RX/TX pins. It's quite simple though. As far as firmware programming is concerned, I need to see the datasheet of sensors. I have rich experience in Arduino IDE/ESP IDF for ESP firmware programming. I'd like to discuss the project in detail via chat. Best Regards Cristian Silva

Hello, I am very confident about your project because I have developed lots of similar projects related to RF IoT device based on ESP32 WROOM 32 WiFi/BLE module with RS485 or RS232 communication interface. I was responsible for circuit design, PCB design, ESP32 firmware programming (used Arduino IDE and ESP-IDF as the firmware IDE.) and PCB manufacturing/testing. I am familiar with web cloud service and Design for Manufacturing of PCB prototyping so I am sure that your project is a good fit for my skills and experience. I will deliver the best results you desire within a short period of time successfully. Looking forward to discussing the project in more detail. Best regards, David
