Arduino code needed for BME280-Aduino Nano- Modbus slave
Budget: $10 – $30 USD
I need to Pass BLE280 sensor readings (Temperature, Humidity, Pressure) to Arduino Nano and further via Modbus RTU RS485 (I use SCM TTL interface module to connect to a PLC that is acting like a Modbus Master ).
The readings from the BME280 are float numbers and thus the Holding registers must be accordingly.
