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 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 ...

One of the benefits of modern computer-controlled engines is efficiency. These kinds of engines manage the ignition and fueling in a precise manner so that very little fuel wastage occurs. Take, for ...

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 ...

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 ...

Sonoff TH16 is a WiFi relay device powered by Espressif ESP8266 WiSoC, able to handle a load up to 16A (3500Watts @ 220V), and including a jack for sensors. The company recently sent me a sample ...
