## Description

##Introduction This carbon monoxide gas sensor differs from most gas sensors on the market as it does not provide specific gas concentration data. Instead, it detects whether the surrounding environment exceeds or falls below a fixed threshold. It operates on a wide voltage range of 5-24V, with high and low-level outputs. The sensor is equipped with an indicator light for easy observation of its status, making it user-friendly. When the sensor detects a gas concentration above the threshold, it outputs a high-level signal and the indicator light illuminates. Conversely, when the concentration falls below the threshold, it outputs a low-level signal and the indicator light turns off. 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.
