room-temp-sensors

This is a modification of the original code to replace pressure with heatindex calculations

• Added support for gas sensor MQ135

Original code by : https://randomnerdtutorials.com/esp8266-nodemcu-mqtt-publish-bme280-arduino/

Prerequisites

You need to setup a MQTT Broker on the same network as your esp8266

How to setup

Make sure u have Git installed then run

git clone https://github.com/KATT07/room-temp-sensors

if you dont have Git installed (if ur on debian/ubuntu based distro)

sudo apt update 
sudo apt install git

Then open the file in Arduino IDE

goto Sketch > Include Library > Add . ZIP library and select the libraries you’ve just downloaded.

For BME280 need to add the Adafruit BME280 library with dependencies in arduino software.
For MQ135 need to add the MQ135 library in same folder as the code.ino : https://github.com/GeorgK/MQ135.

Hardware:

Connect BME280:
Vcc -> Vcc
Gnd -> Gnd
SCL(Clock) -> D1 pin
SDA(Data) -> D2 pin

Connect MQ135:
Vcc -> Vcc
Gnd -> Gnd
AO -> A0 pin

Software:

Replace the XXX with corresponding values for Software
