Data Harvest SmartQ RF Transmitter Keyfob – Model 3158 [2504]

The Data Harvest RF Transmitter Keyfob is designed for use with the SmartQ RF Electrosmog Detector, providing a simple and effective signal source for demonstrating and investigating radio frequency (RF) radiation. Compact and easy to operate, this keyfob transmitter enables students to generate a known RF signal on demand, making abstract concepts far more tangible.

When used alongside the SmartQ detector, the keyfob helps illustrate how everyday devices emit radio frequency energy. The detector itself is a broad‑bandwidth RF (radio frequency) sensor, capable of detecting electromagnetic radiation across a wide frequency range from 50 MHz to 3 GHz—covering many common sources such as mobile phones, Wi‑Fi routers, and wireless technologies.

Together, the RF transmitter keyfob and detector form a powerful teaching combination, allowing students to explore RF signals in a controlled, safe, and repeatable way during practical science lessons.
