RA02A is a smoke detection alarm. RA02A has a built-in photoelectric smoke detector and buzzer. It can detect the smoke density in the environment, and emit an alarm sound when the smoke density exceeds the default value. At the same time, the alarm data can be transmitted to other devices for display. RA02A adopts the SX1276 wireless communication module.
