The Matter Sense is the worlds smallest waste sensor. It senses waste levels in waste bins, e.g. wheelie bins and dumpsters, allowing for bins to be emptied on a need basis rather than on a fixed schedule. It transmits data via LoRa to the cloud and has an estimated battery life of 15 years. It can be commissioned over NFC with a mobile phone commissioning app. BrainSystems developed the electronics and the embedded firmware.
