Product Overview
The DS4 intelligent gas sensor by Germany's EC Sense utilizes a reliable printed solid-state polymer electrochemical sensor technology, making it an industrial-grade intelligent 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 used in industrial, commercial, civilian, 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 and portable measuring instruments, it saves the housing design costs associated with new product upgrades. Standard three-terminal footprint size (VCC_positive power, GND_negative power, IO_data transmission/reception).
Life and Performance Testing
Intelligent gas sensor performance and lifespan self-check, conducting regular self-assessments of lifespan and performance metrics regardless of the presence of test gas, and outputting warning signals to prompt sensor maintenance or replacement. This feature provides reliable foundational data for intelligent instrument design, endowing gas detection instruments with safety, reliability, and remote maintenance capabilities. Users can obtain fault information such as normal operation, weakened sensor performance, sensor failure, or detachment through commands, offering early warnings for sensor anomalies and enhancing safety guarantees.
Factory Pre-Calibration
Each DS4 intelligent gas sensor undergoes professional gas calibration at the factory, with calibration information stored on the product's internal chip. Users can use the sensor directly without the need for additional gas calibration. The factory calibration, utilizing diffused gas calibration and simulated environmental climate calibration methods, is more closely aligned with the actual application environment at the user's site, enhancing the accuracy of data from gas detection instruments using diffused measurement (when gas detection instruments use a pump-suction measurement method, a secondary calibration is required based on the design parameters of the instrument system).
Ready to use without preheating
Intelligent hardware design maintains gas sensors in an operational state even without power, ensuring immediate gas monitoring upon powering up anywhere, anytime. Whether in IoT applications or battery-powered scenarios, our energy-efficient and low-power design eliminates concerns about long preheating wait times and slow data acquisition.
User-Defined Encryption Code Feature
Users can customize their own user codes for identification on the instrument. When inserting other types, the instrument can automatically verify if the user code is correct. For incorrect user codes, the instrument will display an error message to remind 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-identifying function
The DS4 sensor outputs identity information, such as gas type and detection range, which facilitates the design of self-identification features and offers greater flexibility in use.
Simple and easy-to-use UART digital output
The DS4 sensor utilizes a UART 3.3V half-duplex single-bus output signal, eliminating the need for complex communication protocols. It directly outputs the gas concentration value, making the design of secondary development applications flexible and straightforward.
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-click factory reset calibration design. Plug and Play achieves offline calibration,
No need to introduce hazardous gases into the testing environment for instrument calibration, which avoids safety risks and contamination of the on-site environment, making maintenance safer, more convenient, and simpler.
