This intermediate kit transforms two Arduino Unos into a reliable sensor data bridge using HC-05 modules, perfect for ECE lab assignments and IoT prototyping. Master the same serial protocol that underpins countless embedded systems, then monitor the incoming data on a crisp 16x2 LCD. Everything you need comes pre-tested as a single system, so you spend your hours learning, not debugging component mismatches.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA wireless sensor station that transmits DHT22 environment data from a remote Arduino to a base unit, where readings display on a 16x2 LCD.
