Diagram of battery-free busbar hot-spot monitoring inside a switchgear cabinet: SenseID temperature tags mounted on busbar joints detect a hot spot, are read by a UHF RFID reader, and feed per-joint temperature into asset management (CMMS/SCADA).

Battery-Free Temperature Monitoring for Switchgear: Busbar Hot Spot Detection

2026-06-22 by Mikel Choperena

Battery-free temperature sensors detect busbar hot spots inside live switchgear — no wires, no batteries. How it works, which protocol to choose, and the business case.

Two-panel diagram showing HV asset constraints on the left (sealed, high voltage, long lifecycle, mission-critical, no cables, no batteries) and the seven cross-domain engineering challenges on the right (antenna, energy harvesting, power management, sensor, firmware, communication, software), with a section explaining why the system can't be split across specialists.

Predictive Monitoring for High-Voltage Equipment: Where Owning the Whole System Is the Only Option

2026-06-222026-06-16 by Mikel Choperena

High-voltage switchgear, GIS and transformers are sealed, inaccessible, and mission-critical. Monitoring them requires battery-free sensing — and battery-free sensing requires a team that owns the entire HW/FW/SW/RF stack. Here’s why.

Seven engineering domains radiating from a battery-free sensor tag at the centre — antenna/RF, energy harvesting, power management, firmware, sensor signal conditioning, communication, and software/SDK — showing how each domain interacts with all others, with an arrow pointing to four other cross-domain project types (semiconductor test platforms, industrial test equipment, wireless product development, condition monitoring) that require the same integrated capability.

Why We Build Battery-Free Sensors: The Hardest Proof of Owning the Whole RF/Firmware/Software Stack

Battery-free sensors are our hardest product — and the most demanding proof that we own the complete hardware, firmware, software and wireless/RF stack. Here’s why that matters for your next cross-domain project.

Three-level filter for determining whether an asset needs battery-free sensing — Level 1 (sealed, inaccessible, battery-free is the only option), Level 2 (accessible but maintenance is costly, battery-free eliminates a pain point), Level 3 (accessible with standard maintenance, consider alternatives) — with three qualifying questions.

Does Your Sealed, Inaccessible Asset Actually Need Battery-Free? A Practical Filter

A practical three-question filter to determine whether your monitoring application genuinely needs battery-free sensing, or whether battery-powered or wired alternatives might be simpler and cheaper. Honest guidance on when to call us — and when not to.

Side-by-side comparison of two approaches to a cross-domain project — splitting across four specialist vendors with the integration risk falling on the client, versus one team owning the complete HW plus FW plus SW plus wireless system with integration risk managed internally — illustrated with three real project examples.

When One Vendor Can’t Own It: The Hidden Cost of Splitting a HW/FW/SW + Wireless Project

What happens when a project that needs hardware, firmware, software and wireless to work together gets split across four specialists. The integration risk nobody budgets for — and how to avoid it.

Development path from evaluation to production — Stage 1: KL-OSIRIS as a free evaluation tool for one tag at a time; Stage 2: SENSEID SDK in .NET and Python for building custom multi-tag applications with reader abstraction and sensor data decoding; Stage 3: production with custom engineering, antenna design, housing, and feasibility study. Includes a comparison of what the SDK provides versus what you build yourself, and a list of supported readers.

SENSEID SDK: Building Custom Applications in .NET and Python

The SENSEID SDK gives developers a starting point for building battery-free sensor applications in .NET and Python. What it covers, what it doesn’t, and when you’ll need custom engineering.

EVAL-SNFC-RHAT evaluation board specifications alongside a comparison of all three Kliskatek product lines — SenseID (EPC C1G2), SenseBLE (BLE burst) and SenseNFC (NFC) — showing that SenseNFC uses NFC field energy from smartphones, requires no fixed infrastructure, and operates at near-field range by design.
