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.
