* The total cost for the project is about $ 150.
- Each device has the function of a relay station. This helps the signal to travel further.
- All devices have power saving mode. Nrf24l01 will transmit very little signal, after each state change.
- "BUZZER" sound alarms are integrated in the device: Central Controller, Alarm and Fire alarm, Fire alarm, Water heater, Air-conditioner remote control.
- Alarm loudspeaker connects to Central Controller and "Alarm and Fire alarm". Alarm loudspeaker gives very strong sound.
- In the event of a fire alarm, all equipment will ring.
- There are two alarm modes when there is a burglar: + the underground alarm is just dialing two phone numbers. + Sound alarm, turn on the lights and call 2 phone numbers.
- All devices are linked together through wireless communication to form a network.
- Each device is a separate code, which depends on the central controller, so there will be no coincidence. First time use, will have to configure the device. Configuration is quite simple, users just press the button on the device about 6 seconds.
