Additional Features:
- Equipped with a high-performance microprocessor, high-precision
ADC, and intelligent algorithms for easy integration into IoT and
other monitoring systems.
- Each sensor undergoes professional gas calibration at the factory,
with calibration information stored in the internal chip—no need
for users to perform gas calibration again.
- Features intelligent self-checking for sensor performance and
lifespan, regularly detecting and outputting warning signals.
- Supports user-defined sleep and wake modes, suitable for low-power
battery or IoT applications.
- Can output identity information (e.g., gas type, detection range)
to facilitate self-identification function design.
- Provides user-definable codes for instrument recognition,
preventing misinsertion of other sensor types.
