TX711 - A70 Battery - Powered Low - Power Infrared Methane Sensor For Civil Gas Safety Monitoring Portable Gas Detection Equipment
Product Features:
Ultra - low Power Consumption for Long - term Battery Operation: The sensor adopts a sophisticated circuit design. It supplies power to the light source in a pulsed manner and conducts intelligent signal processing. This design minimizes average power consumption, enabling the sensor to operate continuously for a long time relying on battery power and perfectly adapting to battery - powered application scenarios.
Compact Structure with High Optical Efficiency: Through exquisite engineering design, it achieves the maximum optical path length and light efficiency within a small volume. The compact size not only reduces installation space requirements but also lowers the integration difficulty, facilitating its installation in various devices with limited space.
High Reliability and Stable Detection Performance: Based on the NDIR technology, which is an excellent solution for methane detection, the sensor has strong anti - interference ability. It can stably and accurately detect methane concentration without being easily affected by other interfering gases, ensuring the reliability of detection data in complex environments.
Low Application Threshold and Easy Integration: As an integrated sensor platform, it lowers the application threshold of high - performance gas monitoring technology. It can be easily integrated into various terminal products and systems, allowing more industries and products to quickly obtain methane detection capabilities without complex secondary development.
Application Scenarios:
Civil Gas Safety Monitoring: It can be integrated into household methane detectors, smart kitchen appliances (such as intelligent gas stoves and range hoods), and community gas safety monitoring terminals. It can promptly detect methane leakage in residential and commercial kitchen environments to avoid safety hazards such as explosions and poisoning.
Industrial Methane Leakage Detection: Suitable for gas transmission and distribution pipelines, industrial workshops involving methane use, and other scenarios. It can be connected to industrial control systems via RS485 or CAN bus to realize real - time monitoring of methane concentration on industrial sites and provide early warning for production safety.
Portable Gas Detection Equipment: Due to its low power consumption and battery - operable characteristics, it is an ideal core component for portable methane detectors. It is applicable to the mobile inspection work in fields such as gas engineering maintenance and environmental safety supervision.
Intelligent Safety Monitoring Systems: It can be embedded in intelligent building security systems, smart park environmental monitoring platforms, etc. It serves as a key perception node for gas safety and helps build a comprehensive and intelligent safety early - warning network.
