PROJECT DESCRIPTION

Original :

What a multisensor can do:

Room temperature reading; ( BME 280 sensor: temperature, humidity, pressure, altitude 2)
Indoor Humidity Reading;
Room pressure reading;
Reading the light intensity in the room; ( Analog sensor) 2
Displaying the above parameters on the display; (OLED Display 0.91) 3
Flame / fire sensor and reporting to HA; ( https://botland.com.pl/pl/czujniki-temperatury/4461-czujnik-awodieni-760-1100nm-analogowy.html 9)
When flames are detected, lighting, diode and buzzer are turned on ;
Room lighting - 433MHz remote control;
Control of communication with the control panel on the Arduino Mega - in the absence of communication, the red LED flashes;
Room temperature and lighting control with a 433MHz remote control
Turning off the fire alarm / red led + buzzer by means of a 433MHz remote control
Receiving RF codes 433; ( RF receiver 433 MHz 1)
Communication with Arduino Mega 2560 via RS 485. 9
In addition to Arduino nano, I used Grove - Base Shield for Arduino Nano 1and wires with connectors for Grove that I cut in half and soldered to the sensors 2
I stuffed everything into the housing.
