Simtek's sensors are portable, have a long battery life, and can detect light and motion. Their first product, Duo, is a wireless security sensor that allows users to monitor spaces without connectivity or power. The sensor helps reduce accidents, prevent theft, and enables users to stay updated and receive alerts as soon as their safe boxes are accessed. Simtek's connected products provide security and peace of mind for monitoring safes, storage units, luggage, boats, and more.
