Смысл: The main idea is to provide a theoretical and practical foundation for engineers and hobbyists to correctly select, connect, and program sensors in microcontroller systems, moving beyond trial-and-error toward a principled understanding of electronics.
A technical primer on sensor classification, characteristics, hardware interfacing (Analog, I2C, SPI, 1-Wire), and software implementation for microcontroller-based control systems.
Смысл: The main idea is to provide a technical reference for DIY enthusiasts and engineers on how to select and implement various environmental sensors (temperature, humidity, pressure, and gas) using microcontrollers, emphasizing the trade-offs between precision, range, and complexity.
A detailed technical guide on selecting and interfacing temperature, humidity, pressure, and gas sensors with microcontrollers for climate control systems.
Смысл: The main idea of the text is to provide a technical overview of the various hardware methods available for measuring electrical current and voltage when interfacing with microcontrollers, emphasizing the balance between accuracy, safety (isolation), and cost.
A technical guide explaining the theory and hardware implementation of voltage and current sensors for microcontrollers, comparing shunts, transformers, and Hall effect sensors.
Смысл: The text is a detailed technical walkthrough of a recruitment test for a Senior Hardware Engineer position at Yandex. The author designs a signal conditioning circuit to interface a Pt1000 temperature sensor with an ADC, moving from a basic implementation to a high-precision professional solution.
A professional engineer solves a Yandex test task by designing a high-precision interface circuit for a Pt1000 temperature sensor using current sources and differential amplifiers.
Смысл: The main idea is to document the iterative R&D process of selecting the most efficient and cost-effective sensor for measuring water in a kettle, concluding that weight-based (tensometric) measurement is superior to capacitive or conductive methods in a high-temperature, humid environment.
After testing capacitive and electrode sensors, engineers determined that tensometric sensors (weighing the water) are the most reliable and cost-effective way to track water levels in a smart kettle.
