This design is a office building fire alarm detection system based on NRF24L01, the system requirements are as follows:
1, with 51 single-chip microcomputer;
2, need 2 temperature sensors and 2 smoke sensors to detect the signal, (a temperature plus a smoke sensor numbered 1 to 1 road, the other numbered for 2
3, NRF24L01 wireless communication is used to send data
4, microcontroller showing alarm location and degree of alarm;
5, alarm degree is divided into: early warning and alarm
Warning: the temperature sensor paint or excessive smoke sensor, light flashing, abnormal parameters shown on the display and alarm number
