UMG_Node

UMG_Node provides String based InfluxDB measurements in Line Protocol Format sent via HTTP/UDP to a central InfluxDB instance.

Using this Library

1. Goto Tags to download the latest .zip file and extract the contents to <user>\Documents\Arduino\libraries folder.

2. Rename to folder lincoln-node-v1.2.0 to UMG_Node.

3. Restart your Arduino IDE and use #include <UMG_Node.h> in your code block.

4. Examples can be found in Sketch\Include Library dropdown menu.

Hardware

• Olimex ESP32-PoE

Software

• arduino-esp32 library for ESP32 programming.
  • Install it via Board-Manager from Arduino IDE as mentioned here

External Libraries

• Adafruit_BNO055
• RTClib
• NTPClient

Interfacing

Interface	Hardware Pins	GPIO Pins
I2C	EXT2_7_SCL EXT2_10_SDA UEXT_5_SCL, UEXT_6_SDA	GPIO_13 -> I2C_SDA GPIO_16 -> SCL

Note

In order to use the Olimex PoE module add the following to the beginning of every Arduino Sketch

#define ETH_CLK_MODE ETH_CLOCK_GPIO17_OUT
#define ETH_PHY_POWER 12

#include <ETH.h>
// code

Use ETH_LAN8260 under WiFi for Olimex-ESP32 Gateway with the above mentioned values for initial tests.

Examples
