Hi, If I well understood need to construct a new(at zero) slave(MCU+sensor) temp+hum sensor(for example DHT11 or DHT22) which can communicate via Modbus RTU RS485 with PC software(HMI for example) to can see the temperature and humidity. Please let me know if this is the scope for your project. Thanks and a nice day!

Hello sir, I am thrilled to come across your project involving real-time temperature and humidity monitoring using RS485 (Modbus RTU) sensors. As a skilled and experienced professional with a strong background in RS485, Modbus, and LED/LCD technologies, I believe I am well-suited to assist you in achieving your goals. Here's how I plan to proceed with the project: Sensor Integration: I will ensure seamless integration of the RS485 sensor with the telematics device, allowing it to query temperature and humidity values at 15-second intervals using the Modbus RTU protocol, just as you currently do. LED/LCD Display Selection: I understand the need for a robust yet economical LED/LCD display. I will carefully select a display that meets your requirements while being cost-effective. The chosen display will be compatible with the Modbus RTU protocol and capable of displaying real-time temperature and humidity values. Parallel Connection: I will set up a parallel connection between the RS485 sensor and the LED/LCD display, allowing the display to receive and showcase the real-time or last queried temperature and humidity data simultaneously with the telematics device. Thank you for considering my proposal. I look forward to collaborating with you on this exciting project.
