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 ...

前回STEP16ではブレーキスイッチ信号を入力しクルーズコントロールや、アイドルアップ制御の準備が進みました。 今回は純正のナローバンド O2センサー 信号をLINK ECUに入力します。 HA22Sの純正ECUピンアサイン 34PINコネクタの24番 OXがO2センサ信号になってい ...

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 ...

This is a simple app that can be run on a Wink Relay to turn it into a generic MQTT device. It will send button pushes, sensor data, and motion (proximity sensor) detection to the configured MQTT ...

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 ...
