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.
