—This work presents the design and implementation of a wireless sensor network (WSN) from first principles, i.e. without the use of commercial WSN platforms. Specifically, a modular multi-hop WSN was built for humidity, temperature and soil wetness measurements, towards precision agriculture applications. We describe the modules developed for radio(More)
