“…Therefore, applying an energy-saving mechanism to prolong the uptime. To save energy, several power-saving techniques have been used in the literature, such as duty cycling, transmitted data reduction, transceiver optimization, energy-provision schemes, overhead protocol reduction, voltage control, and current control [16][17][18][19][20][21][22][23] WSNs employ many cutting-edge energy management strategies. By creating symmetric clusters, Barzegari and Mossadry devised a c-means clustering technique [24].…”

<p>People have become increasingly aware of the environment in which they live in recent years. This awareness has prompted the development of a reliable environmental monitoring system. This paper presents an energy-efficient and low-power sensor node that could be used for outdoor Internet of Things (IoT) applications to monitor real-time environment conditions such as humidity and temperature remotely. The proposed sensor node could directly connect with a cellular base station over GSM/GPRS quad-bands 850MHz,900MHz,1800MHz, and 1900MHz without needing any Access Point(AP) in the network. The sensor node consists of a central controller based on Atmega328, a communication module on SIM800, DHT22 temperature, and a humidity sensor with a solar-powered charging system. The system is specially designed for robust IoT outdoor applications such as environment monitoring in wilds, large-scale farms, forests, etc. For optimal usage of the power of the battery, an energy-saving mechanism is proposed based on deep sleep scheduling, thus considerably reducing the power consumption and prolonging the up-time of the sensor node. </p>

“…In the case of continuous energy flow, a battery-less scheme can be used. A relative work is a four-supercapacitor CMOS storage bank, which offers high energy utilization [16]. In case of interrupted energy flow, the supercapacitors are not able to provide long-term storage, and a battery should be used.…”

An Ultra-Low-Power CMOS Supercapacitor Storage Unit for Energy Harvesting Applications

This work presents an ultra-low-power CMOS supercapacitor storage unit suitable for a plethora of low-power autonomous applications. The proposed unit exploits the unregulated voltage output of harvesting circuits (i.e., DC-DC converters) and redirects the power to the storage elements and the working loads. Being able to adapt to the input energy conditions and the connected loads' supply demands offers extended survival to the system with the self-startup operation and voltage regulation. A low-complexity control unit is implemented which is composed of power switches, comparators and logic gates and is able to supervise two supercapacitors, a small and a larger one, as well as a backup battery. Two separate power outputs are offered for external load connection which can be controlled by a separate unit (e.g., microcontroller). Furthermore, user-controlled parameters such as charging and discharging supercapacitor voltage thresholds, provide increased versatility to the system. The storage unit was designed and fabricated in a 0.18 um standard CMOS process and operates with ultra-low current consumption of 432 nA at 2.3 V. The experimental results validate the proper operation of the overall structure.
