4-Series & 7-Series Sensor Modules

The 7 Smart Sensor Module consists of a data collection and processing PCB assembly, a SemeaTech 7-Series electrochemical (EC) sensor, and a metal enclosure. The PCB assembly in the module collects the data from the gas sensor output and then processes it with amplification, sampling, filtration, and compensation through a built-in MCU to deliver stable and accurate digital output reflecting the actual target gas concentration. Any of SemeaTech 7-series EC sensors and 4-electrode EC sensors can be used to form a 7 Smart Sensor Module to detect the target gas with the digital output. This module provides the convenience and friendly user experience for users to quickly integrate gas sensors into their existing systems for a variety of gas detection applications.

The 4ECM-Smart Sensor Module (with metal casing) and the 4ECM-Smart Module PCBA consists of a data collection and processing PCB assembly, for the SemeaTech 4-Series electrochemical (EC) sensor. The PCB assembly in the module collects the data from the gas sensor output, and then processes it with amplification, sampling, filtration, and temperature compensation through a built-in MCU to deliver stable and accurate digital output reflecting the actual target gas concentration. Any of SemeaTech 4-series EC sensors can be used to form a 4ECM-Smart Sensor Module that delivers the signal output through UART bus, which provides a good user experience for quickly integrating gas sensors into the existing systems for a variety of gas detection applications. This module has the function of automatic short-circuit pin. For the zero bias sensor, it can be used stably after 30 minutes of power on. For the sensor with bias voltage, it is recommended that the user power on for more than 24 hours before use.
The 4LEL-Smart Sensor Module (with metal casing) and the 4LEL-Smart Module PCBA (without casing) consists of a data collection and processing PCB assembly for the SemeaTech 4-Series Catalytic combustion (LEL) sensor. The PCB assembly in the module collects the data from the gas sensor output, and then processes it with amplification, sampling and filtration through a built-in MCU to deliver stable and accurate digital output reflecting the actual target gas concentration. The 4LEL-Smart Sensor Module delivers the signal output through UART bus, which provides a good user experience for quickly integrating gas sensors into the existing systems for a variety of gas detection applications.
