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.
· Unified electrical interface, mechanical dimensions and communication protocol;
· Working with all SemeaTech 7-series EC sensors and 4-electrode EC sensors;
· Built-in temperature and humidity sensors for better environmental independence;
· Multiple output interfaces, including USART, and I²C;
· Equipped with metal case (optional), it can protect the internal circuit from dust and water;
· Programmable I²C address for user friendly interfaces.
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. Users can visit the
