DM-CG-S/T High Sensitivity Smoke Sensor

DM-CG-S/T-001-A54L20-12 Combustible Gas Concentration and Smoke Sensor exhibits high sensitivity particularly to liquefied petroleum gas, natural gas, propane, and smoke, making it suitable for qualitative measurement of combustible gas leaks and smoke. As a field acquisition slave station, it outputs RS485 digital signals following the standard MODBUS-RTU communication protocol, ideal for long-distance network transmission. Fully compatible with configuration software such as KingView and other upper computer systems, it easily integrates with third-party devices. Widely applicable in IoT environmental monitoring fields including agricultural greenhouses, smart breeding, smart homes, intelligent transportation, factories, and commercial buildings.

Product Introduction

Overview

The DM-CG-S/T high-sensitivity smoke sensor utilizes an SnO2 gas-sensitive semiconductor probe. It detects combustible gas concentrations and smoke with particularly high sensitivity to liquefied petroleum gas, natural gas, propane, and smoke, enabling qualitative measurement of combustible gas leaks and smoke. Functioning as a field acquisition slave station, it outputs RS485 digital signals compliant with the standard MODBUS-RTU communication protocol, suitable for long-distance networked transmission. Fully compatible with various upper computer configuration software like KingView, it facilitates easy integration with third-party equipment. Applications span agricultural greenhouses, smart breeding, smart homes, intelligent transportation, factories, and commercial buildings in IoT environmental monitoring.
