Data from Anywhere
Quick Answer
What protocols does the Halogen MP5 support — Modbus, BACnet, Ethernet/IP, 4–20 mA?
Halogen sensors support three connectivity paths — cellular IoT, Sensus AMI, and BLE for third-party integration. Whether you need a fully autonomous remote monitoring solution or integration into existing infrastructure, there's a module for your deployment. All options include a waterproof battery enclosure for sites without utility power.
Quick Comparison
| Module | Model | Connectivity | Dashboard | Requires |
|---|---|---|---|---|
| Halogen Cellular IoT | IoT-B | Built-in LTE/4G | Halogen Cloud | Nothing extra |
| Sensus AMI Gateway | BT420-BAT | Bluetooth → AMI | Xylem Data Lake | Sensus Gateway |
| BLE SmartBox | BT-B | BLE + Modbus | Third-party | Third-party IoT/SCADA |
Supported Protocols & Integrations
Through the D20 controller, Halogen MP-series sensors speak the industrial protocols your existing infrastructure already uses — from legacy 4–20 mA loops to modern Modbus, BACnet, Ethernet/IP, and cellular IoT.
Modbus RTU (RS-485)
Standard on every D20 controller. Connects MP-series sensors to PLCs, RTUs, and SCADA over RS-485.
Modbus TCP
Optional daughter board adds Modbus TCP over Ethernet for SCADA and historian integration.
BACnet
Optional BACnet support feeds chlorine, pH, and temperature data into building automation / BMS systems.
Ethernet/IP
Optional Ethernet/IP for Rockwell / Allen-Bradley PLC environments.
4–20 mA analog
Standard analog output for any measured parameter — drop-in compatibility with legacy controllers and chemical dosing pumps.
Cellular (LTE-M / NB-IoT)
Optional cellular modem streams readings to a cloud dashboard from remote sites with no wired network.
Halogen Cellular IoT Module
The IoT-B is Halogen's built-in cellular solution for completely autonomous remote monitoring. Transmits sensor data over LTE/4G to the Halogen cloud dashboard with no external hardware required. Optional low-profile antenna available for installations with limited vertical clearance.

Sensus AMI Smart Gateway Interface
The BT420-BAT interfaces the Halogen MP5/MP6 sensor directly with Sensus FlexNet AMI Smart Gateways. Transmits four 4-20mA sensor outputs to the Xylem Data Lake for integration with existing AMI infrastructure. Used by the City of Gainesville, GA for demand-based automatic flushing.

BLE SmartBox — Third-Party IoT Module
The BT-B Bluetooth SmartBox provides Bluetooth Low Energy (BLE) connectivity and a mobile app interface for integrating the MP5/MP6 sensor into any third-party IoT modem or controller system. Power-saving mode disconnects the sensor between measurements to maximize battery life at remote sites.

- check_circle"Measure Now" command synchronizes with grab sample collection
- check_circleMagnetic switch activates Bluetooth for one hour when on-site
- check_circleOnboard SD card enables future sensor firmware updates
- check_circleWaterproof IP68 enclosure, optional 100 AH LiFePO4 battery enclosure
Waterproof Battery Enclosure — All Modules
All three connectivity modules are available with an optional IP68-rated waterproof battery enclosure that holds 50 to 100 AH rechargeable batteries (battery not included). This enables fully off-grid deployment at sites without utility power — vaults, manholes, meter boxes, and outdoor installations in any weather condition.
Common Deployment Scenarios
Remote monitoring gives technical teams real-time visibility into residual chlorine levels from anywhere — whether at the treatment plant, in the field, or at a central control center. Fewer manual site visits, faster anomaly response, and continuous compliance data.
Dead-End Distribution Monitoring
Deploy at remote dead ends without utility power. Battery + cellular transmits chlorine, pH, and temperature data continuously — triggering flushing alerts automatically.
Unattended Remote Sites
Reservoirs, water towers, rural booster stations — any site without power or communications infrastructure. Up to 6 months of unattended operation per battery charge.
AMI System Integration
Utilities already on Sensus FlexNet can add water quality monitoring to existing AMI infrastructure — no new network, no new dashboard, just another data stream.
SCADA & Third-Party Controllers
The BLE SmartBox enables integration with any Modbus-capable controller or IoT gateway — SCADA systems, building automation, or custom IIoT deployments.
