The design of Low Power Embedded Systems (LPES) and IoT products may include a variety of power management techniques, or they may incorporate sophisticated on-chip capabilities that assist in reduced power usage. The power management and low power consumption of embedded systems are also enabled by complex algorithms, and every Low Power System (LPS) may require a mix of approaches to avoid using extra battery power. There are several strategies we may use when creating an LPES that must be extremely power efficient while simultaneously offering the necessary degree of computational capability. It all depends on the design specifications that must be met. Then, if at all feasible, choose the appropriate low-power components from Low Power Electronics (LPE). After studying and reviewing multiple LPES real-time projects, we compiled a list of a few strategies we may use to approach low-power design and consumption for embedded systems. Following the analysis of numerous LPES real-time projects, we came up with a list of a few approaches to low-power design for embedded systems using LPE. There are additional benefits of LPES design. Less heat is generated through LPES, which is better for the environment. For 1000 LPES devices, one watt of power saved per device equals one KWH i.e. we can save 1 unit of electricity. Design with low power increases the component and system reliability. The embedded system's operating life is enhanced. In many instances, LPES designs may result in a reduction in production costs. The LPE components chosen are more affordable and inexpensive. Hence, the low-wattage power supply, LPES design is easier and less expensive.
