A JSN-SR04T ultrasonic sensor, connected to an ESP8266 to calculate the water level in a water tank. Water level monitor using open-source microcontrollers (Arduino, ESP8266, ESP32) and ultrasonic ...

The article describes the implementation of the ESP32 microcontroller in the Watmonitor project, while it is programmed in the ESP-IDF framework environment. The task blocking mechanism - Queue, which ...

Water level monitor using open-source microcontrollers (Arduino, ESP8266, ESP32) and ultrasonic sensors HC-SR04 / JSN-SR04T and similar with Trigger and Echo signals. Arduino Core & ESP-IDF ...

Today, those imperfect sensors have been replaced by options that measure any change you could possibly imagine: temperature and humidity changes, vibration, the presence of water, smoke ...

The sensors will cost less than $10 each and are designed to detect opening doors and windows, motion indoors and out, and leaking water. The sensors will cost less than $10 each and are designed ...

Add these to your home and you'll be alerted if water drips or leaks instantly. Each sensor is equipped with a blaring 100dB audible alarm and sends a push notification to your phone if triggered.

When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant. As soon as the ...

In this article, we focus on the use of graphene in water sensors, exploring how these sensors detect common contaminants, including heavy metals, microbes and irregular pH. Various types of sensors ...

The power of Espressif’s ESP32-S3 meets Arduino’s unmatched customer experience, documentation and community — all in the compact form factor of the Nano. Provides support for both ...
