Four SenseBLE evaluation boards — EVAL-SBLE-AT (ambient temperature), EVAL-SBLE-RHAT (humidity and temperature), EVAL-SBLE-ACC (3-axis accelerometer), and EVAL-SBLE-MGF (magnetometer) — each at 50 euros, powered by UHF RF harvesting, communicating via BLE advertising bursts receivable by any BLE device.

Complete guide to the SenseBLE evaluation boards. Four battery-free sensor tags that communicate via BLE advertising bursts — same sensors as SenseID, lower infrastructure cost. All at 50 € and readable by any BLE device.

Side-by-side comparison showing EPC C1G2 path (single RFID reader with same-band TX and RX, higher cost) versus BLE burst path (separate RF transmitter and BLE gateway in different bands, lower combined cost), with a section showing what stays the same: sensor, accuracy, range, and data.

Why UHF RFID readers cost more than RF transmitters plus BLE gateways, when each option makes economic sense, and how to think about total cost of ownership for battery-free sensor deployments.

Diagram showing one shared sensing core at the top branching into three protocol paths — SenseID (EPC C1G2), SenseBLE (BLE burst) and SenseNFC (NFC) — each with different infrastructure requirements but identical sensing capabilities.

SenseID, SenseBLE and SenseNFC use the same battery-free sensors. The difference is the communication protocol and the infrastructure you need. Here’s how to choose.
