Four Sensors, Complete Protection
Every Smart Monitor includes four precision sensors that work together to give you complete visibility into your basement environment.
Ultrasonic Water Level Sensor
HC-SR04 ultrasonic sensor measures distance to water surface in your sump pit with millimeter precision.
- Range: 2cm – 400cm, ±3mm accuracy
- Calculates fill rate (cm/min) to predict overflow
- Detects pump activation when level drops suddenly
- Readings every 30 seconds for real-time monitoring
Capacitive Flood Sensor
Zero-corrosion design with no exposed metal contacts for reliable floor-level water detection.
- 5-second detection latency — instant alerts
- Place anywhere on your basement floor
- Daisy-chain up to 4 pads per hub for full coverage
- Works in standing water up to 5cm deep
BME280 Environmental Sensor
Precision humidity, temperature, and barometric pressure monitoring for mold risk detection and storm correlation.
- Humidity: 0-100% RH, ±1% accuracy
- Temperature: -40°C to +85°C, ±0.5°C
- Barometric pressure: 300-1100 hPa
- Pressure drops correlate with incoming storms
- Mold risk alerts trigger above 60% RH for 48+ hours
CT Clamp Pump Monitor
SCT-013 non-invasive current sensor clamps around your pump power cable to monitor performance without any wiring.
- Non-invasive installation — just clip around cable
- Detects pump on/off, runtime per cycle, power draw
- Calculates cycles/hour, duty cycle, energy usage
- Anomaly detection: pump running >5 min = blockage alert
- No electrical work needed — safe DIY installation
