WiFi-connected Lux-sensor

This project is for building a WiFi-connected Lux-sensor for the garage. The sensor reads the lux-value once every 10 seconds, and sends the value to the server once a minute.

The sensor used is Adafruit TSL2561 with I2C-Id: 0x39

WiFi ssid and password are stored in a file called config.h, which is not commited to git but looks like this:

#define WIFI_SSID "WiFi-ssid"
#define WIFI_PASSWORD "password"

Sensor connections:

Colour	ESP8266	Sensor
Red	+3.3V	+3.3V
Black	GND	GND
Yellow	GPIO4	SDA
Blue	GPIO5	SCL
