CRU: Floods, RISC-V for Linux, Iron-Scopes and More

AB Open has announced a partnership with Flood Network to bring a series of Internet of Things (IoT) river level sensors to the Upper Calder Valley, providing valuable flood warning data for the region. Joining the users of the Things Calderdale LoRaWAN network, the flood sensors are to be built by AB Open and transmit…
