Product Features
Standard Industrial Dimensions
Standard industrial 4 series size design, 20 x 16.6mm cylindrical housing, allowing for easy iteration of new product designs. Suitable for fixed gas detectors and portable detection instruments, it saves costs associated with housing design for new product upgrades. Standard three-terminal pin size (VCC_positive power, GND_negative power, IO_data transmission).
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 of measured gas, and outputting warning signals to prompt sensor maintenance or replacement. This feature provides reliable baseline 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 them directly without the need for further gas calibration. The factory calibration, utilizing diffused gas calibration and simulated environmental climate calibration methods, is more 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 are equipped with a pump suction measurement method, a secondary calibration is required based on the design parameters of the instrument system).
No preheating required
Intelligent hardware design keeps gas sensors operational even without power, ensuring immediate gas monitoring upon powering up at any time and place. Whether in IoT applications or battery-powered scenarios, there's no need to worry about long preheating wait times or slow data acquisition due to energy-saving and low-power designs.
User-Defined Encryption Code Feature
Users can customize their own user codes for identification purposes 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 prompt 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 patterns, suitable for low-power battery or IoT applications.
Self-Identification Function
DS4 sensor outputs identity information such as gas type, detection range, etc., facilitating the design of self-identification features for greater flexibility.
Simple and easy-to-use UART digital output
The DS4 sensor utilizes UART 3.3V half-duplex single bus mode output signals, eliminating the need for complex communication protocols. It directly outputs the gas concentration value, making secondary development application design flexible, simple, and quick.
Convenient maintenance
Plug and Play, hot-pluggable with live power, open calibration protocols, supports offline recalibration for after-sales service, and one-touch factory reset design. Plug and Play enables offline calibration, eliminating the need to introduce hazardous gases into the detection environment for instrument calibration, thus avoiding safety risks and environmental contamination, making maintenance safer, more convenient, and simpler.
