Light sensors are probably one of the most common sensors in life, they can be found in your laptop, phone or home lighting system. A light sensor measures the level of light in a room or ambient light in a space. This module uses a...

This is an Arduino hydrogen gas sensor. It has high sensitivity to Hydrogen (H2) and less sensitivity to alcohol, LPG,cooking fumes . Hydrogen gas is highly flammable and will burn in air at a very wide range of concentrations The...

The concentration of carbon dioxide (0.03% usuallly) is related to daily life. Recently, there’s a study showing that the atmospheric CO2 content has reached 0.0385% (385 ppm) which is the highest value since 2.1 million years. The raise...

What's the difference between Raspberry Pi and Arduino? We all know Raspberry Pi is a mini-computer running on Linux operating system; while Arduino is a microcontroller running on simple I/Os. Both of them focuses on very different...
