Definition ∞ A low power sensor is an electronic device that detects environmental changes with minimal energy consumption. This type of sensor is engineered for extended operation using limited energy resources, making it suitable for deployment in remote or battery-dependent Internet of Things applications. It collects specific environmental data, such as temperature or motion, and transmits it efficiently. The design prioritizes energy efficiency to maximize operational lifespan without frequent power replenishment.
Context ∞ Low power sensors are becoming increasingly relevant for feeding real-world data into blockchain networks via oracle services, enabling decentralized applications to interact with physical environments. Ensuring the security and integrity of data transmitted from these resource-constrained devices to the blockchain is a significant challenge. Future developments focus on integrating lightweight cryptographic solutions directly into sensor hardware to bolster data authenticity.
