Pulsed AnalogVia pairingPair analog input with digital output for pulsed excitation readings

Connectivity & Build

Built for the field, not the lab.

  • Private LoRa — 22 dBm TX, 3 dBi antenna, 915 MHz, AES-128 encrypted
  • WiFi/BT connectivity coming — close-range industrial deployments within Base Station WiFi range
  • On-device AI inference coming — anomaly detection and process intelligence at the edge
  • IP67 / NEMA 4X ruggedized enclosure
  • 6–36V DC power input
  • Peripherals specified per deployment — customer-supplied or sourced by us at 10% markup

Use Cases

Where Terminal Indi works.

RO Membrane Cleaning

Flow rates, pressure differentials, temperature, chemical timing. Every cycle documented. Every anomaly flagged.

Piloting now with Falcon Water Tech

Pump & Lift Stations

Flow, pressure, level, power draw — on your phone. Alerts before failures. Stop driving, start seeing.

4-20mA connects to your existing transmitters

Tank Level Monitoring

Water, wastewater, chemical storage. Real-time levels with trend data. Overflow prevention.

No more "I thought someone was watching it"

Remote Equipment

Generators, compressors, HVAC — any industrial asset too far from the control room to wire. If it has a sensor, we can read it.

6–36V DC, deploy anywhere
