This little project will show you how to use a soil moisture sensor.

Simple project to measure temperature (with two sensors) and humidity, and send them to the terminal (monitor) and also to a LCD display.

How to use the small module to measure distance for high frequency applications... or low.

Use three HC-SR04 ultrasound sensors and two battery displays to show you how close the obstacles are and from which side.

How I built an Arduino energy monitor and data logger to collect energy data for different loads and plotted that data using Excel.

Now we can check out the depth of the sea level by using a pressure sensor (MS5803–01 BA) connected to an Arduino, and display sensor data.

This Bolt IoT-based project shows how to build a metal detector alert monitor.

Spending $1,000 on suspension repairs because the city failed to fix the potholes? This project makes sure that never happens again.

In this project, we're going to use the DHT11 humidity and temperature sensor to calculate the average temperature and humidity every hour.

This is an Arduino Uno with a DHT11 temp/humidity sensor with and LCD screen powered by a power bank.

Use the DHT Temperature Sensors in C# code via a C++ Windows Runtime Component to implement a one-wire protocol on Windows 10 and the RPI2.

In this protip, I will show you how to build DS18B20 Digital Thermometer with Arduino.

In this tutorial, we will learn how to detect Smoke and inflammable gases using an MQ-2 sensor.
