CO2 NDIR Module

General B-530 module is designed to measure co2 level in the air. This product is maintenance free, low cost and easily intergrated into other equipment especially. B-530 simultaneously transmits a calibrated digital and analog output signal. Its compact size and low power consumption makes easy to intergrated into a broad range of equipment. All modules are factory calibration and ready to install and applicable to portable as well as stationary equipment including wall-mountable fixtures. Features Pre-calibrated Flexible 3 and 7 pin connection Two available outputs : UART, AVO Non-Dispersive Infrared(NDIR) technology used to measure CO2 levels Provides output signal proportional to co2 level. Model available to interact with other devices Gold-plated sensor provides long-term calibration stability.
