In this project we will be using the 4G LTE Network and a Radar Human Presence sensor to create a new and modern alarm system. Due to the 4G Network and LTE-M you can send alarm notifications super fast to your phone, while it costs you pretty much nothing. Combine that with a precise radar and loud siren and you got yourself an awesome alarm system that will protect your treasures ;-) Let's get started!
