Fig 1: Author’s prototype of Automatic Water Level Indicator and Controller The code is written in Arduino IDE. First, the IDE must be installed. The code can then be downloaded and opened in Arduino ...

In this article, we will learn how to similar speed sensor using Arduino and IR sensor. By setting up the two IR sensors at a fixed distance from each other, we can track the time it takes for the ...

💧 Monitoring water tanker level using NodeMCU ESP8266 and HC-SR04P Ultrasonic Sensor and broadcasting it using a simple HTTP server inside NodeMCU ESP8266 and show data in an Android App Using ...

The initial plan was just to have water level sensors reporting data over a modified CATS packet radio transmitter. On the other end, the plan was to capture the feed via a CATS receiver ...

Abstract: This article proposes a low cost of USD 72.5 BoM with a small size of water level monitoring IoT sensor without Ultra-Sonic level sensors. The power consumption for sensing and RF ...

Submersible level transmitters offer a proactive solution by monitoring water levels in roadside drainage ditches and preventing flooding emergencies. These transmitters measure hydrostatic water ...

I n recent years, integrating smart home devices into your living space has never been simpler. They have become easier to set up with user-friendly apps and step-by-step guides, ...

Traditional fire sensors rely on batteries to operate during power outages, but these batteries can explode during fires. In contrast, HV systems draw energy from water, where the device is partially ...

Basically we have the Arduino Uno R4 which will read the soil moisture level using the soil moisture sensor. If the moisture is low it will automatically turn on the water pump via the relay module.

Abstract: This paper presents a novel liquid level monitoring system based on passive ultra-high ... solving the problems of existing RFID sensors and providing a practical, reliable and ...

A demo of Ambient Sensing for Zigbee lights shows how smart lights could soon be used as motion sensors with just a ... based lighting setups to the next level, with presence sensing tech.
