This project involves using an Arduino to monitor flow rate using a sensor connected to an Ethernet shield. The data is processed and sent to an MQTT server every five minutes. The project leverages ...

Arduino driver for the PAA5100JE and Pixart PMW3901 (not tested atm) optical flow sensors. The driver was originally developed to support the Bitcraze Flow Breakout board. It communicates with the ...

Emergence of Controlled Environment Agriculture (CEA) ranging from computer controlled water irrigation system to lightning and ventilation has changed the conventional scenario of farming. This paper ...

Apart from the basic sensors, I have used many different sensors. Be it a water flow sensor, solenoid valve, or an analog multiplexer IC (CD4051), all these sensors helped me to almost nullify the ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

We have designed an IoT based water flow meter. It is powered by the ESP32-S3 SoC from Espressif. We have used an ESP32-S3 Wroom 1 module for the project which will be much easier to handle when ...

In this article, we present a pH meter that can accurately measure the pH value of a solution. We use a dedicated sensor, the Arduino UNO R4 Minima board.
