MH-411D infrared gas sensor is a miniature universal intelligent sensor, which adopts NDIR theory to detect concentration of CO2 in air and has good selectivity, stable performance, long life, also is independent of Oxygen. The inside temperature sensor could be used for temperature compensation. This miniature infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, micro machine workout and superior circuit design. Application Widely used for HVAC refrigeration, industrial-process control and safety protection,agriculture and animal husbandry. Features High sensitivity, high resolution, low power consumption, fast response time Output method: UART, analog voltage signal Temperature compensation, excellent linear output Long lifespan, excellent stability, anti-poisons, anti-vapor interference Specifications Table 1.
