ESP8266 with ALL the sensors

Well, maybe not all of them, but the whole lot that you get with "AOQDQDQD® ESP8266 Weather Station Kit with Temperature Humidity Atmosphetic Pressure Light Sensor 0.96 Display for Arduino IDE IoT Starter".

I'm not going to review the connections for the DHT11 & 1306 (those are on the first Arduino related page).
You'll need the breadboard (or some wire wrapping skills) to connect everything at once)
The BMP (pressure & temperature) sensor uses exactly the same connections as the screen.
VCC to 3V
GND to G
SCL to D1
SDA to D2


The BH1750 light sensor is connected the same too, but has an extra pin labelled ADD. Either leave it unconnected or connect it to ground.

That was simple! You'll need to install those extra libraries BMP085 & hp_1750 in order to use the sensors.

Now all that we need is a sketch to read the sensors, show them on the screen & to broadcast them to the MQTT broker. It's fairly long, but is really just an extension of the shorter ones on the previous page. Credit to randomnerdtutorials, Stefan Armborst & probably someone else - I've just merged these into a single sketch that is entirely self hosted.

Copy the sketch to your Arduino IDE, then edit: ssid, password, TOPIC_BASE, xxx, yyy (& any of the other #define lines that you want to ) & you should be good to go.
N.B. the server only shows the DHT11 temp & pressure - I'm sure that you could extend it to show more if you wanted to.
