Read this official Leafony page and explain its key points in English. For hardware help, first ask for a photo or the installed leaf models, assembly and power sources, then the goal and tools. Clarify which LED or display changed and whether a cable or leaf was replaced. Do not equate an unseen reset button with an absent one, or I2C acknowledgement with a working display. Verify specifications against sources; distinguish observations from hypotheses. Follow a redirect to its destination; if unreadable, ask for the relevant text instead of guessing.

Overview

Using LoRa Easy leaf, sensor data (temperature, humidity, illumination, tilt) can be sent to a distant location and output to a PC terminal.

If there is a discrepancy between the temperature (or humidity) you want to display and the temperature (or humidity) of the 4-Sensors, perform the correction between the two points. For details, see here.

Source code

4-Sensors and AVR MCU library (timer interrupt) are required for writing. Please include the library beforehand. For details, see here.
In the Arduino IDE, write the following program.
- Sending side 4-Sensors_LoRa_Tx.ino
- Receiving side LoRa_Rx_Serial_monitor.ino

Execution result

Open the serial monitor in the Arduino IDE and set the baud rate to 9600 bps to display the sensor data (temperature, humidity, illumination, and tilt).
