SPOTTER PLATFORM

### Pressure Sensor

Add a rugged, piezoresistive subsurface pressure sensor to your Spotter Platform to monitor water level in real time.

Combine with Spotter’s built-in barometer to track tidal changes, measure precise water depths, and detect storm surge.

## Deployment & Best Practices

**Configuration Options**

Ideal for moored coastal deployments with one Spotter or a network. Integrate up to two more devices (e.g. pressure/oxygen) per Smart Mooring (max 3 total).

**Remote Configuration & Controls**

Direct control via Spotter Dashboard, binary/ASCII commands, and Sofar remote support.

**Maintenance and Calibration**

Mount with sensor head (pressure port) pointing downward to prevent debris clogging. Rinse with fresh water after retrieval. Recalibrate annually to offset drift (±0.05% FS/year).
