Product Overview

The DS4 smart gas sensor by Germany's EC Sense utilizes reliable printed solid polymer electrochemical sensor technology, making it an industrial-grade smart gas sensor.

Compact structure with small volume, featuring a high-performance microprocessor, a high-precision analog-to-digital converter, and intelligent algorithm design, easily integrates into the Internet of Things and other monitoring systems.

Widely applied in industrial, commercial, residential, and medical fields.

Product Features

Standard Industrial Dimensions

Standard industrial 4 series dimensions, 20 x 16.6mm cylindrical housing, allowing for easy iteration design of new products, suitable for fixed gas detectors,

Portable test instrument, saving the shell design cost brought by new product upgrades. Standard three-terminal pin size (VCC_positive power, GND_negative power, IO_data transmission/reception).

Life Span and Performance Testing

Intelligent gas sensor performance and lifespan self-check, conducting regular self-assessments of lifespan and performance metrics, regardless of the presence or absence of measured gas, and outputting warning signals.

Prompt for sensor maintenance or sensor replacement. This feature provides a reliable foundation of data for the intelligent instrument design, enabling the gas detection instrument to have safety and reliability.

Achieve remote maintenance. Users can retrieve fault information such as normal operation of sensors, weak sensor performance, sensor failure, or detachment through commands.

Early warning of sensor anomalies provided to users, enhancing security.

Factory Pre-Calibration

Each DS4 intelligent gas sensor undergoes professional gas calibration at the factory, with calibration information stored on the internal chip of the product, allowing users to use it directly.

No need for additional air calibration. The factory calibration utilizes diffused gas calibration and a simulated environmental climate calibration method that is more akin to the actual application environment at the user's site.

Enhanced the accuracy of data from gas detection instruments using diffusion measurement (Secondary calibration is required based on the design parameters of the instrument system when using pump suction measurement mode.)

No preheating required

Intelligent hardware design allows the gas sensor to remain operational even without power, ensuring immediate gas monitoring can commence upon powering up at any time and place.

In both IoT applications and battery-powered devices, worry not about long preheating wait times and slow data acquisition during energy-saving and low-power design.

User-defined encrypted code feature

Users can customize their own user codes for identification on the meter. The meter can automatically verify if the user code is correct when inserting other types.

For incorrect user codes, the instrument can display an error message, prompting the user to insert the correct sensor.

Low-power sleep mode feature

The sensor features a sleep mode, allowing users to customize sleep and wake-up modes, suitable for low-power battery or IoT applications.

Self-Identification Function

The DS4 sensor outputs identity information, such as gas type and detection range, facilitating the design of self-identification functions and enhancing flexibility in use.

Simple and easy-to-use UART digital output

The DS4 sensor outputs signals in UART 3.3V half-duplex single bus mode, directly providing gas concentration values without the need for complex communication protocols.

Make secondary application design flexible, simple, and quick.

Convenient maintenance

Plug and Play, hot-pluggable with power, open calibration protocol, supports secondary offline calibration for after-sales service, and one-button factory reset design.

Plug and play with offline calibration; no need to bring hazardous gases into the detection environment for instrument calibration, thereby avoiding safety risks and contamination of the on-site environment.

Make maintenance safer, easier, and simpler.
