This IR motion sensor relay switch circuit is designed for use with all kinds of medium-power automobile/domestic 12V DC loads. It is a simple solid-state relay (SSR) switch, controlled by a standard ...

This program is written in Python 2. It collects and stores sensor data (O2, CO2, and Humidity) attached to a Raspberry Pi. It also controls a motor pump through a relay switch. By running ...

Abstract: We propose a destination-aided wireless energy transfer scheme in wireless relay sensor networks, where the power of the information collector who has stable power supply is fully exploited.

A Infineon XMC1100 powered system used to switch between 2 USB Devices and to control a relay based on a sensor input with configurable hysteresis.

Abstract: In wireless sensor networks, relay node placement has been proposed to improve energy efficiency. In this paper, we study two-tiered constrained relay node placement problems, where the ...

With fuel prices rising, the need for accurate air/fuel mixture monitoring is more important than ever. The engine computer needs to know what the fuel mixture is with a high degree of precision so it ...
