An air quality notification device (1) is disclosed. The air quality notification device (1) includes an actuating and sensing module (10), a microprocessor (20), a first communication module (30) and a power source (40). The actuating and sensing module (10) includes a sensor (11) and an actuating device (13). The actuating device (13) is disposed near the sensor (11). The sensor (11) senses air transmitted by the actuating device (13) to generate air quality information. The microprocessor (20) is electrically connected to the actuating and sensing module (10). The first communication module (30) is electrically connected to the actuating and sensing module (10) to receive and transmit the air quality information. The power source (40) is electrically connected to the microprocessor (20).
