MQ-2 Smoke Sensor Module DC5-30V Smoke Alarm Module Switch Controller Smoke Sensor Relay Switch Kitchen Smoke Detection Sound And Light Alarm

• ACCURATE DETECTION: This module is capable of detecting smoke density and enables users to set a smoke detection threshold. When the smoke concentration exceeds the preset value, the relay closes, the alarm indicator lights up and the buzzer sounds an al
• ALARM FUNCTION: The sensor module triggers an alarm, relays, and indicator lights when the detected smoke concentration exceeds the set threshold. Conversely, the alarm, relay, and indicator lights cease when the smoke level drops below the threshold.
• PRACTICAL FEATURES: The sensor module features a multi alert buzzer and offers relay switch output for enhanced alert notifications and response.
• PROTECTION: The sensor module has reverse connection protection capabilities to prevent dangers associated with incorrect power supply connection.
• WIDE APPLICATIONS: Our smoke sensor module is ideal for usage in public transport, public spaces, storage warehouses, and kitchens, providing safety and reassurance in areas susceptible to fires.
