Block diagram of electrical power supply"},"content":{"rendered":"<p>The block diagram illustrates the electrical power supply system of a telemetry and sensor device. The system is powered by a 3.7V 2800mAh Li-Po battery, which is connected to a DC-DC step-up voltage converter (MT3608) that boosts the voltage to 5V. This 5V line is distributed to various components.<\/p>\n<p>The CPU, an ESP-WROOM-32 (NodeMCU ESP32 DevKit V1), receives 5V and internally regulates the voltage to 3.3V using its built-in voltage regulator. The ESP32 then supplies 3.3V to various sensors and peripherals, ensuring proper operation.<\/p>\n<p>The telemetry module, an RFD900X operating at 915MHz, is powered directly by the 5V line to enable long-range communication of up to 40 km. Additionally, a Catalex storage module (SD card) is powered with 5V for data logging.<\/p>\n<p>The system includes several sensors operating at 3.3V:<\/p>\n<ul>\n<li>BNO055: A 9-degree-of-freedom sensor integrating a magnetometer, accelerometer, and gyroscope.<\/li>\n<li>Two GY-MS5837-30BA sensors: Used to measure temperature and absolute pressure.<\/li>\n<li>ZP5210: A sensor designed for liquid level measurement.<\/li>\n<\/ul>\n<p>This power distribution ensures that each component receives the necessary voltage levels, maintaining system efficiency and reliability.<\/p>\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"583\" src=\"https:\/\/biotechcell.com.pe\/wp-content\/uploads\/2025\/03\/IMAGEN-3-1024x583.jpg\" alt=\"\" class=\"wp-image-1691\" srcset=\"https:\/\/biotechcell.com.pe\/wp-content\/uploads\/2025\/03\/IMAGEN-3-1024x583.jpg 1024w, https:\/\/biotechcell.com.pe\/wp-content\/uploads\/2025\/03\/IMAGEN-3-300x171.jpg 300w, https:\/\/biotechcell.com.pe\/wp-content\/uploads\/2025\/03\/IMAGEN-3-768x438.jpg 768w, https:\/\/biotechcell.com.pe\/wp-content\/uploads\/2025\/03\/IMAGEN-3-18x10.jpg 18w, https:\/\/biotechcell.com.pe\/wp-content\/uploads\/2025\/03\/IMAGEN-3.jpg 1241w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>","protected":false},"excerpt":{"rendered":"<p> [&hellip;]<\/p>","protected":false},"author":2,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-1686","page","type-page","status-publish","hentry","post"],"_links":{"self":[{"href":"https:\/\/biotechcell.com.pe\/en\/wp-json\/wp\/v2\/pages\/1686","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/biotechcell.com.pe\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/biotechcell.com.pe\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/biotechcell.com.pe\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/biotechcell.com.pe\/en\/wp-json\/wp\/v2\/comments?post=1686"}],"version-history":[{"count":2,"href":"https:\/\/biotechcell.com.pe\/en\/wp-json\/wp\/v2\/pages\/1686\/revisions"}],"predecessor-version":[{"id":1692,"href":"https:\/\/biotechcell.com.pe\/en\/wp-json\/wp\/v2\/pages\/1686\/revisions\/1692"}],"wp:attachment":[{"href":"https:\/\/biotechcell.com.pe\/en\/wp-json\/wp\/v2\/media?parent=1686"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
