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 ...

Ultrasensitive molecular detection and quantization are crucial for many applications including clinical diagnostics, functional proteomics, and drug discovery; however, conventional biochemical ...

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 ...

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: We consider a wireless sensor network made of sensor nodes capable of sensing and communication, relay nodes capable of communication, and base stations responsible for collecting data ...

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 ...
