DTS-4O2 Smart Digital Oxygen Gas Sensor Module For Industrial Safety Monitoring

                             DTS-4O2 Smart Digital Oxygen Gas Sensor Module For Industrial Safety Monitoring

Product Overview:

The DTS4 - O2 smart digital gas sensor module is based on printed solid - state polymer electrochemical sensing technology. It is an industrial - grade smart gas sensor with a compact structure design, integrating a high - performance microprocessor, a high - precision analog - to - digital converter, and intelligent algorithm design. It can be easily integrated into the Internet of Things and other monitoring systems, and is widely used in industrial, commercial, civil and medical fields.

Technical Principles

It uses three electrodes made of precious metals. When the gas diffuses into the sensor through the porous membrane, it will undergo oxidation or reduction, triggering an electrochemical reaction, generating a current proportional to the gas concentration, so as to realize the detection of gas concentration.

Product Features:

• High - precision and reliable measurement: Each DTS4 smart gas sensor has been professionally calibrated for gas in the factory, and the calibration information is stored in the internal chip of the product. The detection range of DS4 - O2 can reach 0 - 30% vol, the accuracy is < ± 1% FS, and the resolution can reach 0.01% vol.
• Fast response: The response time T90 < 20s, which can quickly and timely capture the change of gas concentration.
• Strong environmental adaptability: The working temperature range is - 40℃ to + 55℃, and the working humidity range is 15 - 95% RH (non - condensing), which can work normally in high - humidity and other harsh environments. The solidified design of the electrolyte avoids the risk of liquid leakage caused by high - humidity environment or material aging.
• Convenient integration and use: It adopts the output signal of UART 3.3V half - duplex single - bus mode, which directly outputs the gas concentration value without cumbersome communication protocols, making the secondary development and application design flexible, simple and fast. It also has functions such as plug - and - play, hot - swappable, and can output identity information such as gas type and detection range, which is convenient for the design of self - identification function.
• Low power consumption and long - life: The power consumption is ≤ 5mW @ 5V DC, and the expected life of the sensor in the air is > 5 years. It also has a sleep function, and users can customize the sleep and wake - up modes, which is suitable for low - power battery or IoT applications.

Product use:

• Industrial Safety Monitoring: It is used to monitor the oxygen concentration in industrial environments such as mines, tunnels and subway tunnels to ensure the safety of workers. In these environments, if the oxygen concentration is too low or too high, it may pose a threat to the health and safety of workers, and the sensor can detect oxygen concentration changes in time to provide early - warning.
• Industrial Process Control: In some chemical reactions and combustion processes, monitoring the oxygen concentration can help optimize the process. For example, in the fuel cell system, by monitoring the oxygen concentration, the efficiency of the fuel cell can be ensured, and the reaction conditions can be controlled in the chemical and pharmaceutical industries to ensure production safety and product quality.
• Environmental Monitoring: It can be used to detect the oxygen level in the atmosphere to assist in assessing air quality, which is of great significance for environmental protection and ecological research.
• Civil Use and Smart Home: As an important part of smart homes and smart cities, it can provide a more intelligent, comfortable and safe living environment. For example, it can monitor the oxygen concentration in the room to ensure the air quality in the living environment and help people create a more comfortable living space.
• Medical Field: It can be used in medical devices such as ventilators and anesthesia equipment for oxygen concentration detection to ensure the accuracy of oxygen supply and help doctors better treat patients.
• Food Industry: By monitoring the oxygen level in the food packaging environment, the shelf - life of food can be extended, and the quality and safety of food can be ensured.
• Grain Storage: It is suitable for the oxygen - controlled/ventilation control scenarios of high - temperature and high - humidity grain storage. By monitoring the oxygen concentration in the grain storage, combined with the intelligent fan control system, the closed - loop control of the automatic ventilation and air - conditioning grain storage strategy can be realized to prevent the grain from heating and mildewing.
