Weatherstation setup with ESP8266, DHT11, and BMP280

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
• DHT11 sensor
• BMP280 sensor

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. I have the DHT sensor serving temperature data in celcius and faharenheit. 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 the setup is pretty simple

I am using an esp8266-MOD

the dht11 sensor is connected like this:

• sensor + ---> esp 3.3v
• sensor gnd ---> esp gnd
• sensor sense ---> esp D3 (gpio 0)

the bmp280 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)

download the .ino file and alter to your specification
