Nexisense TX711-A70: Empowering a New Smart Safety Ecosystem

With the rapid adoption of IoT and smart cities, gas safety monitoring is no longer about "if" but about "how accurate, durable, and intelligent". Traditional methane sensors often consume high power requiring mains electricity, or are prone to false alarms and have short lifespans, or are bulky and cannot penetrate complex environments. These limitations have long restricted large-scale deployment of high-performance gas monitoring technologies.

The Nexisense TX711-A70 changes this completely.

This battery-powered low-power infrared methane sensor combines extreme performance, bringing high-end infrared monitoring technology from labs to everyday devices and scenarios, giving each terminal and node a reliable "sense of gas".

Why it’s a “disruptive leap”

Most infrared gas sensors are associated with high power consumption, high cost, and a need for stable power supply. The TX711-A70 reduces average power to milliwatt levels and can reach microwatt levels in intermittent mode. A single standard lithium battery can power the device for months or even over a year, making battery-driven high-performance methane monitoring a practical reality.

Meanwhile, it retains core infrared advantages:

• High selectivity for methane, unaffected by alcohol, cooking fumes, humidity, or CO

• Over 10 years of lifespan, with no regular sensor replacement needed

• Excellent anti-poisoning capability, eliminating the failure risk seen in catalytic sensors

Encased in a compact, battery-powered module, this top-tier performance significantly lowers the industry threshold.

Reducing burden for portable devices

Traditional handheld methane detectors require frequent charging and often weigh over 0.5kg. The TX711-A70 enables "months of handheld operation".

• Device weight < 200g

• Continuous standby over 3 months

• 2 hours daily usage lasts over 6 months

  
  

Frontline personnel can leave chargers behind and focus entirely on site safety.

Enabling wireless sensor networks

In city gas valve wells, underground utility tunnels, tunnels, and greenhouses without mains power, wired sensors fail, and battery-powered semiconductor sensors generate false alarms. The TX711-A70 enables reliable distributed wireless methane monitoring.

Dozens or hundreds of sensor nodes can be installed once and require nearly zero maintenance for ten years. Using LoRa, NB-IoT, or 4G/5G modules, data is uploaded in real-time to the cloud, generating city-wide methane heat maps. Leaks trigger second-level alerts, achieving early leak detection and hazard mitigation.

Bringing true peace of mind to smart homes

Traditional semiconductor sensors trigger false alarms from cooking fumes, alcohol, or cleaning agents. The TX711-A70’s high selectivity ensures it responds only to methane. When integrated with smart home platforms, it can automatically shut off valves, activate fans, and send notifications.

Unlocking emerging markets

• Biogas and landfills: Accurate methane measurement for energy optimization and emission control

• Smart agriculture and livestock: Real-time methane monitoring in barns and biogas pools

• New energy pipelines: Precise methane monitoring when blending hydrogen with natural gas

• Cold chain and grain storage: Detect trace methane for early spoilage warning

Conclusion

The TX711-A70 is not just a sensor iteration; it democratizes high-performance gas monitoring. It brings infrared technology previously limited to large enterprises and major projects into homes, urban environments, and the hands of developers and startups. With every device and node having reliable methane sensing, smart safety becomes tangible and actionable.

Choosing TX711-A70 means smarter, longer-lasting, and more effortless safety. The future has arrived.
