Compact structure with a small footprint, 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.

Broadly 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 users to easily iterate new product designs, suitable for fixed gas detectors and portable measuring instruments.

Saved costs on the shell design for new product upgrades. Standard three-terminal pin 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-inspections of lifespan and performance metrics regardless of the presence of measured gas, and outputting warning signals.

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

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

Early warning of sensor anomalies provided to users, enhancing safety assurance.

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 ventilation calibration. The factory calibration utilizes diffused gas calibration and a simulated environmental climate calibration method, which is more similar to the actual application environment at the user's site.

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

No preheating required

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

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

User-defined encrypted code feature

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

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

Low-power sleep function

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

Self-identifying feature

DS4 sensor outputs identity information, such as gas type and detection range, facilitating the design of self-identification features for greater flexibility.

Simple and easy-to-use UART digital output

The DS4 sensor employs UART 3.3V output signals in a half-duplex single bus mode, directly outputting 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 on, open calibration protocols, supports secondary offline calibration for after-sales service, and one-button factory reset calibration design.

Plug and play with offline calibration; eliminates the need to introduce hazardous gases into the detection environment for instrument calibration, thus avoiding safety risks and environmental contamination.

Make maintenance safer, easier, and simpler.
