ESP8266 based SensorNode

In last weeks I put together a Sensor-Node based on ESP8266. The software part provides:
  • the standard WiFiMonitor to setup the WiFi credentials
  • a web page to configure the connected sensors
  • a web service to read the configuration and current sensor values
  • the data are published via MQTT in a format to be feed into a influxdb
The following sensors are supported:
  • DS18B20 (multiple)
  • BME280
  • Si7021

I designed a board to be put into a USB port with a temperature and a humidity sensor.
