Here in this project we are gonna build a circuit using MQ-2 sensor which is used to detect smoke. If there is any unusual activity near the sensor, alert will be send to the particular user.

Last hour air temperature,pressure, humidity. Daily max, min, average temperature.

"Development of a Roaming Robot with Humidity and Temperature System: An Internet of Things (IoT)-Based Prototype"

Reading temperature, humidity, barometric pressure and dewing point using dht 11, bmp 180 and node mcu using arduino ide through raspberry pi from a home in Oslo and sending the data to thingspeak for seeing the output in a userfriendly user interface

CO2, NH3 gases have to measure in this system
