Carbon Monoxide Threshold Alarm Sensor (0-1000ppm) | 5-24V Safety Detector

This instant-alert carbon monoxide detector eliminates guesswork with factory-calibrated threshold technology, delivering clear danger/no-danger signals for workplaces, labs, and smart homes.

Instant Threshold Alerts

No data interpretation needed – bright LED + high/low digital signals (5-24V) activate immediately when CO exceeds 20ppm threshold, matching OSHA safety guidelines.

Wide Voltage Compatibility

Works seamlessly with 5-24V systems (Arduino/Raspberry Pi/industrial controllers) without extra regulators. Consumes ＜10mA standby power for 24/7 monitoring.

Maintenance-Free Reliability

Precision electrochemical cell guarantees ＜2% reading drift over 8 years. Withstands -10°C to 50°C extremes and 90% humidity – ideal for basements/workshops.

Industrial-Grade Safety Design

Flame-retardant PVC housing resists heat/chemical exposure. 50cm cable enables flexible installation near risk zones (heaters/garages).

Note: The threshold of this sensor is factory-fixed and cannot be modified by the user. Custom threshold parameters can be set for bulk orders.

If you need to measure Carbon Monoxide concentration accurately, we recommend the Fermion: MEMS Carbon Monoxide CO Gas Detection Sensor.
