Embedded systems often require a range of low-power devices and components to ensure the system can operate efficiently in battery-powered or low-power environments. Here are some common low-power devices and components commonly used in embedded systems:
Low-power processors: Embedded systems often use low-power processors such as the ARM Cortex-M series to perform computing tasks. These processors are designed to operate under low power conditions with low energy consumption.
Low-power sensors: Sensors are used to monitor environmental parameters such as temperature, humidity, light, motion, etc. Choosing low-power sensors can help extend battery life.
Low-power communication module: If the embedded system requires remote communication, choosing a low-power communication module (such as LoRa, Narrowband IoT) can help reduce energy consumption.
Low-power storage: Embedded systems usually need to store data, such as flash memory or EEPROM, and low-power storage devices should be selected to reduce power consumption when reading and writing data.
Low-power display: If the embedded system requires a display screen, choosing low-power display technology, such as electronic ink (E-ink) or OLED, can reduce power consumption.
Low-power power management chip: Power management chip can effectively manage power supply, control power consumption and extend battery life. This includes features such as voltage regulator, sleep mode, power analysis, and more.
Low-power clocks and timers: Low-power clock and timer components help accurately measure time and synchronize operations while reducing energy consumption.
Low-power LEDs: If LED indicators are needed, choosing low-power LEDs can reduce power consumption. In addition, it is also important to use low-power LED driver circuits.
Low-power transmitters and receivers: If the system requires wireless communications, it is important to select low-power transceivers and RF components.
Low-power operating system: Using a specially designed low-power operating system such as FreeRTOS can optimize the energy consumption of the system.
Low-Power Consumption Batteries: The ultimate source of energy is the battery and it is crucial to choose a battery type that is efficient and has low power consumption.
