This project provides the Arduino software for an ESP12E temperature sensor.
The ESP12E measures the temperature and humidity with a DHT 22 sensor and sends the values via Wifi to an MQTT server.
The hardware design with a step by step instruction can be found on https://www.vogt.or.at/hardware/temperaturesensor.

The necessary 3rd party libraries are listed in arduino-temperature.ino.
The software can be configured in b_config.ino.
The working mode can be set in the file a_constants.ino.
If no connection to the Wifi or MQTT can be made, a log file is written. The log file can be printed with the WORK_MODE_PRINT_LOGFILES constant. The changed program has to be uploaded to print the log file.
