Introduction


In this story, I descripe how I built a TTN-Node to meassure and visualize the different temperatures of my heating system:

  • inlet temperature

  • return temperature

  • temperatur oft the hot water tank

  • outside temperature

  • Also I messure the humidtiy with a DHT11-Sensor on the board.

First I used a breadboard to connect RFM95W Radio with a Arduino Pro Micro 3.3V. But I don´t like breadboards so I designed a quit simple PCB-Board that fits into a nice and cheap enclosure.

I share the EAGLE-Files, also I will make some surplus PCB-Boards available on Tindie...
