The SparkFun OpenScale – IoT project is a ready-to-use ESP32-based IoT smart scale with open-source hardware and firmware support that makes it easy to read precise weight data from load cells without ...

This project presents a portable Arduino-based digital instrument for railway track inspection that measures super elevation (cant), track gauge, and rail temperature. Built around an Arduino Nano, ...

This water level and temperature monitoring system uses contact or non-contact water level sensors along with a probe-type temperature sensor. A digital display provides continuous, real-time ...

The length is 32 hexadecimal digits + four hyphens = 36 characters. Note that the hexadecimal digits are all lower case (by specification). The user may convert this to upper case if needed. The 0.1.1 ...

The exact time and date are obtained from the Network Time Protocol via Wi-Fi. For a smaller display, about 0.8-inch schematic diagram is very simple. Problems are with large segments, containing more ...

In one of our previous tutorials, we have shown you how you can interface LM35 Temperature Sensor with Arduino because it's cheap, easy to use, and requires minuscule ...

Agriculture is the backbone of our country and it is very important to know the parameter of soil and water for efficient harvesting. The various parameters that can be monitored are Soil moisture, pH ...
