In particular, we will distinguish between the high-power state, in\u003cbr\u003ewhich all operational phases such as initialization, sensing, transmitting, and receiving take place, and\u003cbr\u003ethe low-power state, in which the device remains in sleep or idle mode.\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eWe will show that current consumption in the low-power stage is a key factor in reducing overall\u003cbr\u003eenergy usage during operational cycles. The lower the current in this stage and the longer its duration, \u003cbr\u003ethe lower the total power consumption of the device. In our target system, the average current in the\u003cbr\u003elow-power stage is expected to be around 15  A.\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eThis book and its laboratories will involve three types of communication links and three categories\u003cbr\u003eof terminal devices. Directly connected devices will operate using Wi-Fi links, close devices will\u003cbr\u003euse the Wi-Fi MAC layer through ESP-NOW, and remote devices will rely on long-range LoRa radio\u003cbr\u003elinks. Close and remote devices will require intermediate router or gateway nodes to access the\u003cbr\u003eInternet using the IP protocol.\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eThe analysis and optimization of power (current) consumption will be carried out using the Power\u003cbr\u003eProfiler Kit II (PPK2). This measurement device will allow us to observe and analyze the current\u003cbr\u003econsumption of the connected IoT development kits.\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eUsing the PPK2, we will optimize power consumption by introducing control parameters such as\u003cbr\u003edelta, cycle time, and threshold value. These parameters will enable us to tune the power\u003cbr\u003econsumption to the required level.\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eBy comparing the energy efficiency of different radio links such as Wi-Fi, ESP-NOW, and LoRa, we\u003cbr\u003ewill demonstrate that, during the high-power state, the transmission phase accounts for the largest\u003cbr\u003eshare of energy consumption. This cost will be highest for Wi-Fi communication and for long\u003cbr\u003etransmission phases with LoRa radio links.\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eFinally, the laboratories will show that the lowest energy consumption can be achieved using ESP-\u003cbr\u003eNOW packet transmission and LoRa packet transmission with short packets and low spreading\u003cbr\u003efactors, such as SF7 or SF8.\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eThese labs may be considered a starting point for the development of more specific applications using\u003cbr\u003evarious types of sensors, actuators, and terminal devices. The DevKits, available in the form of Gerber\u003cbr\u003efiles, can be produced and adapted for use in professional teaching classes as well as in industrial\u003cbr\u003edevelopment laboratories.\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eAll development software presented in this book and in the associated laboratories is implemented\u003cbr\u003eusing \u003cb\u003eMicroPython\u003c\/b\u003e. The use of MicroPython allows rapid prototyping and clear program structure\u003cbr\u003ewhile maintaining direct access to the hardware features of the IoT SoCs. This approach makes the\u003cbr\u003elaboratories accessible for educational purposes while remaining suitable for advanced experimentation\u003cbr\u003eand low-power optimization.\u003cbr\u003e \u003c\/p\u003e","brand":"Independently Published","offers":[{"title":"Paperback","offer_id":47568585392279,"sku":"9798250324496","price":1517.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9798250324496.webp?v=1774869439","url":"https:\/\/atlanticbooks.com\/products\/practical-introduction-to-low-power-iot-architectures-with-esp32-s3-sx1262-nd-micropython-9798250324496","provider":"Atlantic Books","version":"1.0","type":"link"}
