The power management includes two buck converters, an LDO, and eight LED drivers, supporting up to 64 LEDs in an 8 × 8 matrix organization. It makes this system the most complete and versatile sensor ...

Using NodeMCU ESP8266 for controlling switches (Relay). Uses RTC (Real Time Clock - DS3231) and NTP (Network Time Protocol) for maintaining time. OLED Display (128x64) for instant updates. A webserver ...

This work further explores the scope of TFETs for dual mode transceiver design with resistive sensing circuit for 3D IC and time-to-digital converter (TDC) used in sensor interface circuits for IoT.
