Cubeseries Industrial Relay Modules can reliably switch a multitude of small loads, decouple systems and multiply signals. Designed for flexibility in complex industrial environments, the Cubeseries ...

Abstract: This paper presents an LC passive wireless sensor for monitoring both humidity and pressure by using a relay switch. The LC sensor system consists of an inductor, two capacitors, and a relay ...

Abstract: Near-Field Communication (NFC) has enabled mobile devices to emulate contactless smart cards, which has also rendered them susceptible to relay attacks. Numerous countermeasures have been ...

This project provides firmware for an ESP32-based relay boards which you can find in great number at Aliexpress, Amazon or Botland. Alternatively, you can use this firmware if you want to contol any ...

Arduino library for the SPL06-001 pressure sensor. Derived from Adafruit_Sensor open-source library. Code was developed and tested on an ESP32-S2 microcontroller. Code was tested with I2C ...
