Low-Power Embedded Services for IoT: Optimizing Battery Life and Performance

Every aspect of today’s life is surrounded by advanced computer systems and logistics. Advanced technology encompasses every device in your office and household instrument. The low-power embedded system design is a unique discovery leading to optimized energy usage by energy-consuming systems like battery-powered devices, wireless modes of communication, and many other electronic devices. This low-power embedded technique has effectively played a crucial role in power management by electronic devices, thereby increasing its importance in the market. The embedded systems are usually dedicated to performing in large systems where there is limited power availability. Some of the systems that favor the use of low-power embedded systems include battery-operated devices, remote sensors, and even a USB interface.

Things to Look For While Designing Low-Power Embedded System

1. Keep Track of the Operating Voltage- Keeping the overall operating voltage low is a crucial part of designing power embedded system. It is necessary to keep the overall voltage low as the power consumption of the entire system directly depends on the overall operating voltage. If the chips used in the circuit can go to the lowest level like less than 2 for an entire circuit, then this should be the perfect scenario for designing the low-power embedded system. There are situations where the circuit requires two sets of voltage operators one of 3 volts and another of 2 volts for optimizing power consumption by the integrated circuit. The design should then be one in a way to embed two voltage systems on a single circuit with the incorporation of some advanced digital translation chips along with a DC-DC converter as a backup process. Now the devices for which the circuit designing is taking place are in dire need of a suitable operating voltage. However, to reduce the power consumption of the operating devices, the integrated and embedded chip will require an extra DC-DC convertor or an LDO interface. The power consumption will be considerably less when these procedures are incorporated while designing the low-power advanced design solution.

2. Proper Selection of Components- It is not only about effective power consumption management but also about selecting the specific components or rather the integrated circuits. The proper integrated circuits are the building base of power power-effective system and that too under the specific budget. Therefore special care should be taken while selecting the specific components for the low-power embedded system. For instance, it is better to choose the integrated circuit component that has a label reading to be operating at low power and also lower voltage consumption. There are also other factors to consider while selecting the defined parts of the embedded system. You need to be sure about the manufacturer of the integrated circuit parts. Choose the one who can provide proper and authentic documentation about the working parts. There should be accurate datasheets also depicting the working principle of the parts and its efficacy. There should be proper application-based notes of the IC parts that will help you know the part better in terms of its functioning. It would also help in understanding the testing times of the parts. There should be help from the manufacturer’s end if you are stuck anyway in between understanding the product and its setup. The dedicated engineering team would come to help in between this procedure.

3. Understanding Power Consumption in Wireless Modules- The power consumption in wireless modules plays an integral role in maintaining an overall lower power consumption by the embedded system. It is a wise decision to take into consideration the estimated power consumption of wireless interfaces like WiFi, Bluetooth, wireless sensors, etc., and many other IoT devices. It is better to compare the power consumption timings and other parameters of the interfaces. It is essential to choose the correct technology while utilizing the functions of the embedded system. Choosing the wrong technology while using wireless communication modems may lead to inefficient power utilization.

4. Consider Carefully the On/Off Mechanism- The mechanism of turning on and off the wireless communication modules is important for optimizing power consumption. For instance, keeping the wireless communication modem like the router in power on condition will contribute to its excess power consumption even when actively not in use. If there could be the On/Off control mechanism available with the wireless device it could have been more efficient in maintaining power efficiency.

Benefits of Low Power Embedded System

1. Optimized and Dedicated Functionality- There are specific functions assigned to the low-power embedded system. Therefore, these systems help in performing specialized tasks with high accuracy and efficiency. For example, if an energy-optimized low-power embedded system is designed to perform the vehicle infotainment, it cannot be simultaneously for operating airbags in the car. 
2. High Reliability and Precision- The mode of functioning of the low-power embedded system is highly precise and accurate when it comes to wireless communication. Power or system failure is not an option in the case of an embedded system. There are a lot of advanced systems that rely on low-power embedded systems, one being medical devices. The medical devices work on multiple integrated circuits embedded into a highly functional and energy-optimized system. All the parts need to work efficiently and tirelessly with high precision. For example, you have to rely on the digital automated locking system in the bank for ultimate safety. There is no space for failure. Therefore the embedded system works not only on optimal power consumption but also on accuracy and precision. Another example is that you need to rely on the glucometer to get accurate glucose levels in your body. 

There is no scope for failure as the entire treatment will depend on the precision of readings given by the embedded system. Semiconductor engineering in the USA has paved a unique path towards the development of such low-power embedded systems providing timely outputs even when the initial resources are restrained or scarce. Since a lot of integrated system needs to be embedded into a single unit, the embedded system maintains a unique and compact structure to combat technology-related complications.
