EDTECH: LEVERAGING AI-POWERED TECHNOLOGIES TO TRANSFORM THE LEARNING EXPERIENCE
1. Technology overview
Dragino (Shenzhen Dragino Technology Development Co., Ltd., listed as Open IoT Solution) is based in Shenzhen and sells LoRa and LoRaWAN modules, end nodes and gateways, NB-IoT products and Linux IoT appliances. Its catalog covers environmental, agriculture, water and level sensors.
The SW3L series reads pulses from a water flow sensor and uplinks volume over LoRaWAN v1.0.3 Class A (SW3L-LB and SW3L-LS) or NB-IoT (SW3L-NB). Readings are sent every 20 minutes, with flow status alarms for waste such as a broken toilet. Devices are configured by BLE, AT commands or LoRaWAN downlink.
2. Highlighted features & specifications
- LoRaWAN flow uplink: SW3L-LB and LS report water volume every 20 minutes over LoRaWAN v1.0.3 Class A.
- NB-IoT option: SW3L-NB uplinks over NB-IoT with MQTT, UDP or TCP.
- Flow alarms: detects flow status to flag waste such as a broken toilet.
- Sensor sizes: DW-004 to DW-020 for G1/2 inch to G2 inch pipes with 450 to 12 pulses per liter.
- Configuration: BLE, AT commands and LoRaWAN downlink with OTA firmware update.
- Power: Li-SOCl2 battery for up to 5 years, or solar plus Li-ion on SW3L-LS.
3. Potential application
- Factory water sub-metering with pulse-output flow sensors over LoRaWAN.
- Apartment building toilet and common-area leak monitoring.
4. Benefits
Low-cost retrofit path to remote water monitoring in buildings. Battery life designed for up to 5 years on an 8500mAh Li-SOCl2 cell, or solar option on the LS model. Supports many regional LoRaWAN bands including AS923, EU868 and US915. Over-the-air firmware update and datalog are included.
5. Market trends & opportunities
Building owners and factories add low-cost LoRaWAN sensors to existing water lines to find waste before investing in full smart meter replacement. In Vietnam, industrial parks and apartment complexes can use pulse-output retrofit nodes with local LoRaWAN gateways.
