In this tutorial we will use one soil hygrometer module to measure soil moisture of a pot.
The module can give us a digital signal when the soil need watering and this output can be adjusted by the potentiometer. Or it can give us an analog signal of current soil moisture!
In this tutorial we will use the Sharp IR sensor (GP2Y0A41SK0F) to measure distance from an object.
In this tutorial you will learn how to use one water flow sensor with an Arduino board.
The water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.
In this tutorial we will use the Adafruit BMP280 sensor. This sensor can measure barometric pressure and temperature with very good accuracy. Because pressure changes with altitude we can also use it as an altimeter with ±1 meter accuracy! Accuracy for barometric pressure is ±1 hPa and ±1.0°C for temperature.
In this tutorial you will learn how to use the WizFi210 – serial WiFi Shield with Arduino uno board. This low-cost wifi shield can be easily connected to your WiFi network and communicate with the Arduino uno board through the serial communication protocol. In this tutorial we will control an LED wirelessly from an Android phone/tablet app or from a computer tcp/ip terminal.
