Our Case Studies

NB-IoT Smart Smoke Detector


1. Interconnectable among devices in one floor. Among interconnectable smoke detectors, all sensors will alert once any of them is triggered.

2. Reliable and Independent NB Network

3. Up to 10 years battery life for Dual Batteries. 

4. Alert you via APP rather after accident happens. Local and remote dual alert, family member, neighbors, entity owners etc.

5. Low battery warning- Smoke detector will chirp when the battery is low


1. Residential settings

2. Commercial buildings

3. Industrial factories and warehouses


l. Fault detection and alarm function

2. Selected models have positioning function, built-in sensor status sensing, trigger positioning function for effective detection


3. Wireless transmission of test results

4. Additional functions such as water level detection can be added

1.  Vibration sensor monitors the state of the manhole cover by sensing the measured opening angle of the manhole cover


2. Water level sensor monitors the water level in the manhole to manage urban drainage systems


3. RFID facilitates fixed asset management and operational authority supervision 


4. Positioning sensor adds GPS or BeiDou positioning function to facilitate system supervision and data binding


5. Gas detection sensor allows gas concentration monitoring for specific manhole openings to raise timely alarms
