Product Overview

The product utilizes a composite sensor combining ultrasonic, pressure (optional), and conductivity measurements to detect water levels. Two sets of backup conductivity sensors are responsible for triggering water accumulation alerts, while ultrasonic and pressure (optional) sensors ensure precise water level measurement.

Reporting Frequency: During dry conditions, a safe status report is transmitted every 2 hours (configurable); during water accumulation, reports are sent every 5 minutes (configurable).
Main Technical Parameters

Frequently Asked Questions
How does the AOSL33 detect water levels?
It uses a composite sensing system combining ultrasonic, conductivity, and optional pressure sensors for high-precision measurement and redundant backup.
What is the reporting frequency during emergency waterlogging?
During water accumulation events, the terminal transmits reports every 5 minutes (configurable) to provide real-time monitoring data.
Does the terminal affect the urban landscape after installation?
No, the terminal features a compact design intended for buried installation, ensuring it does not interfere with the aesthetic of municipal roads or parks.
Can the device parameters be adjusted remotely?
Yes, the AOSL33 supports remote OTA (Over-the-Air) updates and remote parameter configuration for both NB-IOT and LORA versions.
What should I consider when choosing between NB-IOT and LORA versions?
NB-IOT is ideal for direct wireless upload where signal strength is better than -80dB. LORA RF is recommended for areas where NB signal stability cannot be confirmed.
Is the battery easy to maintain?
The product is designed for convenient battery replacement, which significantly reduces long-term maintenance costs and complexity.
