This weatherstation will connect to a wifi network, then start a webserver, and serve up the data it collects. This weatherstation will connect to a wifi network, then start a webserver, and serve up the data it collects.
The DHT11 sensor provides temperature and humidity. 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. The BME280 sensor provides temperature, barometric pressure, and altitude.

the bme280 sensor is connected like this: the bme280 sensor is connected like this:
* sensor + ---> esp 3.3v * sensor + ---> esp 3.3v
* sensor gnd ---> esp gnd * sensor gnd ---> esp gnd

* sensor SDA ---> esp SDA (d2/gpio 4) * 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:
