Features
1. Low cost: NB-IoT mode, using operator's network, no need to set up base station equipment, reducing system cost.
2. Easy to install: Wireless communication, built-in battery, no need wire, shorten construction time and reduce construction cost.
3. Easy maintenance: Intelligent operation, real-time monitoring of equipment operating status, and find faults in time.
4. Convenience: Internet operation and management mode, users can receive alarms through WeChat and computers anytime and anywhere.
5. Judging the working status of the detector in time (connecting to the network, powering on, reporting and alarming) through the prompts of the indicating status lights.
6. All-day detection status, 24 hours automatic reporting of equipment status (battery power, heartbeat data, alarm status).
7. Once the gas reaches the concentration threshold, the detector triggers an alarm, the indicator light flashes and the buzzer sounds.
8. Smart power-saving mode design, combined with the use environment, can customize different heartbeat reporting times to improve battery life.
