What Sensorfield does

Sensorfield is a Houston-based private LLC, founded in 2011, that designs and manufactures cellular-connected remote monitoring hardware for industrial and utility applications. Its product platform consists of two layers: (1) transmitters available in Solar, Battery, and Harvester (current-transformer power-harvesting) variants, each providing direct-to-cloud telemetry over cellular modems with planned NTN satellite support, and (2) plug-and-play sensor modules spanning fluid (cable level, radar, sonar, pressure), motion (vibration MEMS, magnetometer position), environmental (temperature, acoustic, radar), and electrical (pulse, 4-20mA, RS-485/Modbus) categories. The company's core technical differentiator is ultra-low-power hardware/firmware design enabling years of autonomous operation on a single battery charge or solar input, plus automatic sensor recognition and a universal adapter cable system that allows third-party 4-20mA and Modbus devices to be integrated into the Sensorfield cloud without custom engineering. Magnetic mounting and self-installable hardware target the operational economics of remote or geographically distributed assets.

The commercial model is one-time hardware sale — explicitly positioned as having "no monthly fees" with all cloud access, APIs, and MQTT forwarding included at no recurring charge. Customer segments are dominated by utilities (underground transformer temperature monitoring, power line transformer temperature monitoring to mitigate wildfire risk, SF6 gas leak detection in UK high-voltage equipment) and oil & gas operators (valve position monitoring, flow measurement, tank level, with case studies including XOG Resources and an unnamed Permian Basin operator). Distribution is direct-only, via a website contact form and phone support (281-631-5926), with multi-carrier SIMs and international MVNO relationships enabling global deployments across nine countries. Marketing consists of corporate website content marketing, case-study-driven solution pages, and a LinkedIn corporate page. A recent product launch introduced an AI-enabled acoustic sensor capable of recognizing programmed sound signatures (e.g., compressor cycling, pressure relief valve activation) on-device, extending the platform's analytics surface beyond physical/electrical measurements.

Core offering

Sensorfield manufactures cellular-connected IoT transmitters (Solar, Battery, and Harvester models) that pair with proprietary plug-and-play sensors across Fluid, Motion, Environmental, and Electrical categories, plus universal 4-20mA and RS-485/Modbus adapters for third-party devices. Hardware transmits data directly to the Sensorfield cloud platform via cellular modem, where customers access readings, alarms, and forwarded data via API or Sparkplug MQTT. The company sells the hardware outright with no subscription or monthly fees.

Product overview

Sensorfield is an IoT remote monitoring platform consisting of sensor categories (Fluid, Motion, Environmental, Electrical) paired with transmitter types (Solar, Battery, Harvester). Sensors are self-installable in minutes and designed for remote locations, while transmitters communicate directly to cloud via cellular modem (with NTN satellite coming soon). The platform features plug-and-play auto-recognition of connected sensors, near-SCADA data capabilities with minute-level transmission, customizable alarm hierarchies, and open API/MQTT integration for data forwarding. Integration cables (4-20mA, RS-485) allow third-party device connectivity. Recent addition includes AI-enabled acoustic sensor for sound-based anomaly detection.
