Key benefits Higher sensitivity and selectivity compared with carbon dioxide sensors, enabling more accurate detection of target gases at low concentrations. Effective output at low signal levels — reliable detection and signaling even when measured values are small. Low-level electrical signals are suitable for direct processing by a single-chip microcomputer, simplifying integration and reducing additional signal-conditioning hardware. Provides an analog output of 0–2 V for straightforward connection to ADC inputs or analog monitoring equipment. Includes instructions for signal output to assist with correct wiring and integration. What this product does Detects target gas with performance optimized for sensitivity and selectivity relative to CO2-based measurement methods. Produces a proportional analog voltage (0–2 V) representing the detected concentration level, suitable for data logging, threshold alarms, or closed-loop control. Compatibility and integration Directly interface to a single-chip microcomputer (microcontroller) without the need for complex amplification when using the provided low-level signals. Analog 0–2 V output is compatible with standard ADC inputs and many data acquisition systems; verify ADC input range and reference voltage when connecting. Includes signal-output instructions to guide proper connection and initial setup. Performance and reliability Designed for effective low-level signal response, improving detection accuracy at low concentrations. Selectivity reduces false positives from CO2 interference compared to CO2-based sensors.
