IoT-Based Proximity Sensor Sump Monitoring Device — Product Specifications
Product Overview
An IoT-enabled proximity sensor–based sump monitoring device designed to measure water levels and pump status in underground or overhead sump tanks. The system uses non-contact sensing technology and wirelessly transmits data using LoRa, Wi-Fi, or LTE to cloud platforms, SCADA systems, or local gateways.
Monitored Parameters
- Water level status (Low / Medium / High)
- Overflow condition detection
- Pump ON / OFF status
- Dry run detection (optional)
- Pump run hours
- Supply voltage
- Signal strength
