<p class="0abstract">IoT concept gained tremendous momentum in this century's technological advancements because it has efficiently connected various devices wirelessly. The ESP8266 Wi-Fi serial transceiver module is one of the most used devices for IoT applications. This paper designs the IoT-based smart street lighting system using ESP8266 configured as a Mesh network. The ESP8266 was instructed (programmed) to control the light level by producing a PWM signal, then it sends a dimmer value and reads the sensor's data. We can access our system wirelessly via a web server. The overall system was successful as a smart street lighting system in a wireless Mesh environment. This research result is also compared to the existing similar project in terms of the system complexity aspect.</p>

In this paper, we report a smart street lighting control system using the ESP8266 which is a low-cost Wi-Fi chip with full TCP/IP stack and microcontroller capability. Our system is equipped with a web server developed in HTML code. Hence, our smart street lighting system can be controlled wirelessly to turn ON or turn OFF, and it can be monitored its environmental condition (i.e., temperature and humidity around the system). All sensors used in this system are pure digitally-outputted sensor: DHT11 to monitor the ambient temperature and humidity and BH1750 to adjust the street light intensity automatically. The dimming technique was applied in the control system by using Pulse Width Modulation (PWM). The system was divided into two main parts: Gateway and Node in which these two parts employ the ESP8266. The Gateway as a coordinator will send a message to the node as an end device (in this work, the streetlight act as a Node). Later, the node will send the ACK to the Gateway. As results, each node can send a message to other nodes.

“…The downscaling of integrated circuit technology, especially CMOS, is pushing the limits of miniaturization and portability. The availability of ultra-low power (µW) and complex monolithic circuits in CMOS nanotechnology opens new research on Internet of Things (IoT) solutions for a wide range of applications [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18], including sensing, data processing, and communication. The power requirement for these systems depends on the application.…”

This paper describes an energy harvesting system composed of an organic photovoltaic cell (OPV) connected to a DC–DC converter, designed in a 130 nm Complementary Metal-Oxide-Semiconductor (CMOS) technology, with a quasi- maximum power point tracking (MPPT) algorithm to maximize the system efficiency, for indoor applications. OPVs are an emerging technology with potential for low cost indoor light energy harvesting. The OPV current-voltage curves (I-V) under an irradiance of solar simulator Oriel Sol 3A, at room temperature, are obtained and an accurate electrical model is derived. The energy harvesting system is subjected to four different indoor light sources: 35 W halogen, 3.5 W LED, 5 W LED, and 7 W LED, positioned at three different heights (0.45 m, 0.26 m, and 0.11 m), to evaluate the potential of the system for indoor applications. The measurements showed maximum efficiencies of 60% for 35 W halogen and 45% for 7 W LED at the highest distance (0.45 m) and between 60% (5 W LED) and 70% (35 W halogen), at the shorter distance (0.11 m). Under irradiation, the integrated CMOS circuit presented a maximum efficiency of 75.76%, which is, to the best of the authors’ knowledge, the best reported power management unit (PMU) energy system using organic photovoltaic cells.
