【High-Accuracy NDIR Sensing】 Dual-wavelength NDIR technology ensures ±(50 ppm + 5% of reading) precision at 25°C; 0–5000 ppm range (extendable to 10,000 ppm); eliminates cross-interference from other gases; Suitable for indoor air quality monitoring in smart homes and offices
【Ultra-Low Power Consumption】 3.3–5.5 V DC wide input voltage; typical 30 mA operating current; integrated sleep mode via ABC logic (Automatic Baseline Correction); extends battery life in portable data loggers and IoT Enviro nmental monitors
【Dual Output Flexibility】 UART interface with Modbus protocol for industrial networks; 0–3 V analog voltage output (linear to 0–5000 ppm); compatible with Arduino (via MAX485 module), Raspberry Pi, and ESP32; supports real-time data logging without complex firmware
【Temperature Robustness & Calibration】 -10°C to +50°C operating range; 0–95% RH humidity tolerance (non-condensing); built-in temperature compensation and ABC logic to counter drift; not for high-pressure (>110 kPa)
【Plug-and-Play Integration】 33.5×20×8.5 mm compact module with pre-wired color-coded cables; 100nF capacitor recommendation for VIN/GND noise suppression; avoid impedance ≤10kΩ on analog output; includes Modbus address configuration guide for rapid deployment
