## Weatherstation setup with ESP8266, and BME280 ### first the facts: I didnt write this code. I altered existing code with a link to author and original code in the .ino weatherstation coding for: * esp8266 * BME280 sensor This weatherstation will connect to a wifi network, then start a webserver, and serve up the data it collects. The BME280 sensor provides temperature, barometric pressure, and altitude. On the BME sensor altitude is reckoned using barometric pressure and sealevel pressure - i didnt want to mess with that because my sensors will be distrubuted. Because of that I set altitude as a contant for the location im setting up for. photo/schematic will be posted soon ![weatherstation pinouts esp8266MOD and bme280](http://dkc-hvac.com/images/projects/esp8266MOD-pins-from-underside.jpg) the setup is pretty simple ### I am using an esp8266-MOD ![esp8266 pinouts](http://dkc-hvac.com/images/projects/esp8266-pinout-map.png) the bme280 sensor is connected like this: * sensor + ---> esp 3.3v * sensor gnd ---> esp gnd * sensor SCL ---> esp SCL (d1/gpio 5) * sensor SDA ---> esp SDA (d2/gpio 4) For the solar charging i wanted to stay as close to a gardenlight as possible - so i am using a 5v 500mAh solar panel and a lm4056 breakout board to charge 4x 1.2v NIMH rechargable batteries, which powers the station. Here is a schematic i got off the net: ![esp8266 solar charge schematic](http://dkc-hvac.com/images/projects/arduino-solar-powered.png) download the .ino file and alter to your specification
