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

The Carbon Monoxide Threshold Alarm Sensor provides simple, factory-calibrated detection for concentrations up to 1000ppm without requiring manual data interpretation. Operating on a wide 5-24V DC input, it is ideally suited to makers, students, and engineers integrating reliable gas safety alerts into smart home setups or industrial microcontroller projects.

Instant threshold alerts

The sensor triggers a digital high signal and an onboard LED when carbon monoxide levels exceed the fixed 20ppm safety threshold. With a response time under 15 seconds, it eliminates the need for complex calibration code in safety-critical monitoring systems.

Wide supply voltage compatibility

Designed to run on 5V to 24V DC, the module interfaces directly with Arduino, Raspberry Pi, and industrial controllers without requiring extra voltage regulators. It consumes less than 10mA in standby and under 100mA during active alerts.

Long-life electrochemical cell

A precision electrochemical sensing element delivers an 8-year operational lifespan with less than 2 percent drift in standard conditions. The flame-retardant PVC housing operates reliably across -10°C to 50°C and 15% to 90% relative humidity.

Compact enclosure dimensions

The unit features an integrated mounting form factor with a 50cm attached lead for flexible positioning near combustion appliances, workshops, or vehicle bays.

Clear connection interface

Standard wire leads provide straightforward power input and a clear high/low binary output for danger and safe states.

Versatile safety applications

Certified to CE and RoHS standards, this detector is suitable for indoor air quality monitoring, lab safety, occupational health compliance, and automated ventilation controls.
