The sensor triggers when the feet come in contact with water; typically, just a few drops set it off. The device then sends a push alert or email (or both) and sounds an alarm.

The purpose of an intelligent alarm analysis system is to provide complete and manageable information to a central alarm station operator by applying alarm processing and fusion techniques to sensor ...

The SGP30 is a digital multi-pixel gas sensor designed foreasy integration into air purifier, demand-controlledventilation, and IoT applications. Sensirion’s CMOSens®technology offers a complete ...

Interview: “Security Should Be Built Into Embedded Systems From the Start, Not Added Later” — Andrew Doukhvalov, Head Of ...

An easily implementable signal conditioning circuit for resistive humidity and temperature sensors is presented. It is based on a relaxation oscillator in which both the frequency and the duty-cycle ...

This is a lightweight C library that helps to interface with ST's VL53L0X time-of-flight distance sensor. It makes it simple to configure the sensor and read range data from it via I²C. I converted ...
