KSCY5 Infrared Ethylene Oxide Gas Sensor Module
Introduction
The KSCY5 infrared ethylene oxide sensor is a gas sensor module that uses the NDIR infrared absorption detection principle. KSCY5 uses MEMS light source, special structure optical cavity and dual-channel detector to achieve spatial dual optical path reference compensation, and the microprocessor performs signal acquisition, processing and output. KSCY5 has good selectivity, high sensitivity, no oxygen dependence, long life and low power consumption; built-in temperature sensor for temperature compensation; also has UART, 485 output and analog current/voltage output; alarm points can be set to facilitate customers to use in different application scenarios.
