A wireless telemetry module is an embedded hardware subsystem that acquires sensor measurements and transmits them over a radio link to a remote receiver without a wired connection. It combines signal conditioning, analogue-to-digital conversion, a microcontroller, and a low-power radio, and is used where wired tethering is impractical, such as implanted devices or remote field sensors. Power efficiency, antenna design, and link reliability are its central engineering constraints.

- Designs integrate ultra-low-power MCUs, energy harvesting or small batteries, and short-range radios (BLE, sub-GHz ISM, or inductive links for implants), often duty-cycling to extend lifetime. For biomedical use, biocompatible packaging and regulatory-compliant emission limits constrain the design, while field-monitoring variants prioritise range and ruggedisation.
