S-M7 sensor module is a highly integrated sensor module. It features with high performance sensor components, microprocessor, analog-to-digital converter, on-board temperature sensor, and accurate full-range temperature compensation and linear correction. S-M7 sensor module adapts the interfaces and packaging of various types of gas sensors, also with both digital and analog voltage outputs. Sensor module is calibrated before shipment, customers can use it without secondary development or calibration. S-M7 sensor module is very suitable for portable and fixed gas detection devices and can reduce the equipment development complexity.
