Continuous Monitoring. Zero Maintenance. Zero Blind Spots.

The Passive Wireless Temperature Monitoring System from PQSense ensures smarter safety for high-voltage environments. Poor cable connections, fractured springs, and aging fuses often look fine, until the moment they overheat and fail.

PQSense brings these invisible risks into plain view. Designed for continuous 24/7 wireless temperature monitoring inside hard-to-access electrical equipment, the system uses battery-free RFID sensors to track temperature changes—without wiring, power, or manual inspections.

The Smarter Way to Monitor Temperature

Unlike traditional systems, PQSense doesn’t rely on batteries or wired power sources. Our passive RFID sensors draw power from a nearby reader and transmit precise, real-time temperature readings—even from inside metal enclosures or switchgear cabinets.

PQSense uses a unique passive RFID sensing technology. Each sensor is wireless, compact, and maintenance-free. It transmits precise temperature data without requiring direct visibility or line of sight.

Once installed on critical hotspots—such as circuit breaker clamps, capacitor terminals, or cable crimp points—each sensor becomes a continuous watchdog. Even in fully enclosed or high-voltage environments, these sensors detect and transmit thermal behavior accurately and safely.

This makes PQSense Passive Wireless Sensors ideal for monitoring blind spots where traditional tools fail.

How It Works

The Passive Wireless Temperature Monitoring System uses a streamlined three-part setup to deliver continuous, battery-free monitoring—without disrupting operations.

1. Passive RFID Sensors
   Installed directly on hotspots—cable terminals, circuit breaker clamps, or capacitor contacts. Fully passive, powered wirelessly by the reader and antenna, they transmit accurate contact-based temperature data.

2. Antennas
   Connected to a reader and placed near sensors in high-voltage areas. Antennas transmit energy and signals between the reader and nearby sensors.

3. Reader
   Mounted externally in the control section, alongside meters, relays, and other monitoring devices. It sends activation signals and collects real-time temperature data. One reader supports up to four antenna ports (ANT1–ANT4), enabling wide-area coverage.

Why It Matters: See What Infrared and Battery Sensors Can’t

Most wireless monitoring systems still rely on batteries, and most inspections rely on infrared tools. But in high-risk industrial environments, both approaches have limits.

Batteries degrade, require replacement, and often fail in high-temperature or high-voltage conditions. Infrared tools need open panels, clear sight lines, and manual operation—leaving blind spots untouched.

PQSense solves both. Its real-time temperature monitoring system is battery-free, requiring no maintenance or replacements. Combined with RFID transmission, it delivers continuous readings even in enclosed equipment.

Where PQSense Delivers: Switchgear, Substations, and Critical Power Systems

The PQSense Passive Wireless Temperature Monitoring System is trusted where downtime is costly and thermal risks are invisible—until it’s too late.

It’s ideal for:

• Substations and transformer rooms

• Semiconductor cleanroom power systems

• Manufacturing line switchgear and MCC panels

• Public transportation infrastructure and UPS enclosures

Wherever traditional inspections fall short, PQSense provides temperature monitoring for switchgear and substations with unmatched reliability.

The Hidden Fire Risk Inside Every Home

Smart Home Insurance is no longer just about covering damages after accidents—it’s about prevention. Residential fires often begin where no one is looking—inside a breaker box, behind a wall socket, or under a stack of old appliances. Overheating wires and loose electrical connections are silent dangers that build up over time, especially in older homes.

Yet most insurance plans step in only after a disaster occurs. But what if insurers could offer homeowners a way to catch these problems before they spark a fire? 

Why Traditional Inspections Often Fall Short

While annual maintenance and safety checks help, they’re not enough to detect slow-building electrical hazards. Loose terminal screws, corroded wiring, or overloaded power strips may not show visible symptoms—until it’s too late.

This is where smart monitoring technology changes the game for Smart Home Insurance providers.

Introducing Smart Monitoring Solutions from PQSense

PQSense offers insurers two sensor-based fire prevention solutions that integrate directly into Smart Home Insurance programs:

1. Continuous Monitoring

Best suited for high-risk homes, older properties, or premium policyholders requiring proactive protection.

How it works:

• Install wireless, battery-free temperature sensors at key electrical locations—such as breaker panels, UPS systems, PowerWalls, or cable junctions.

• Sensors operate 24/7, continuously monitoring heat levels in the background.

• Abnormal temperatures trigger automatic cloud-based alerts, enabling early intervention and ongoing trend tracking through the PQSense dashboard.

2. Handheld Monitoring

Ideal for homes where constant monitoring isn’t necessary, or where sensors are installed behind wooden walls or in visually obstructed areas.

How it works:

• Passive RFID sensors are installed on hotspots like capacitor terminals, lithium battery enclosures, or breaker panel connections.

• Use the PQSense Handheld Device to wirelessly scan nearby sensors, even behind walls or hidden corners.

• All readings are uploaded via mobile app to the cloud dashboard for analysis, alerts, and reporting.

Where Should These Sensors Be Installed?

Whether using continuous or handheld monitoring, PQSense sensors are best placed at:

• Breaker panels (main and sub-panel terminals)

• PowerWalls or UPS system junctions

• Cable junctions or incoming busbars

Both solutions use the same wireless, passive sensor—meaning no batteries, no wiring. That makes them perfect for retrofitting into older homes, a key concern for Smart Home Insurance coverage.

Why This Matters for Insurance Providers

By combining proactive risk detection with flexible deployment, insurers can:

• Prevent costly fire claims before they start

• Create differentiated policies—offering discounts or loyalty rewards to customers with sensors installed

• Provide value-added services through home safety inspections

• Build a data-driven risk model based on real electrical conditions, not just assumptions

This approach allows Smart Home Insurance to move from reactive payouts to prevention-first solutions.
