Gravity: Digital Infrared Motion Sensor For Arduino Introduction
This is a simple to use arduino motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the 'alarm' pin will go low. This sensor checks for infrared heat in it's detecting angle. Human body, pets and several other things emit energy that the sensor is looking for, it compares with the snapshot and if t..
Gravity: Digital Tilt Sensor for Arduino / Raspberry Pi Introduction
This is an arduino tilt sensor. It is used to detect orientation. Inside the sensor, there is a ball that make contact with the pins when the case is upright. Tilt the sensor over and the balls don’t touch, thus not making a connection.Here is the principle of tilt sensor to illustrate how it works: Simple plug to our Arduino IO Sensor Expansion Shield, you can mak..
Gravity: Digital Vibration Sensor Introduction
What's the simplest way to check vibration with Arduino? Use a vibration sensor from DFRobot. You can directly plug it on our IO Expesion Shield V7. Just vibrate this sensor, Arduino can receive a digital signal. It's easy to acount and program in Arduino.
Despite it's simple, you can make full use of it with creative thinking, like step counting, Crash warning light and..

Gravity: Digital Hall Sensor Introduction
what's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You have to feel it by youself.Right！This Hall sensor knows whether there is a magnetic object nearby or not. And it correctly tells you through ditigal output.See below picture for a quick demo!
Note: It's a omnipolar magnet dectector so that it can not tell two polaritie..
Gravity: Digital Microwave Sensor (Motion Detection) Introduction
The microwave sensor applies the Doppler effect to detect moving objects using microwaves. This differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave-reflective, and its sensor readings are not affected by the ambient temperature.
This type of microwave sensor is widely used in industrial, transportatio..
Gravity: Digital Piezo Disk Vibration Sensor Introduction
The DFRobot Vibration Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is propotional with the strength of vibration.So you can know the extent of vibration. Different from digital vibration sensor that only accounts times, this analog one can tell extent of vabiration.
Gravity: Digital PIR (Motion) Sensor For Arduino Introduction
This is a PIR (passive infrared motion) sensor designed to work with Arduino and Raspberry Pi. It allows you to sense motion, it is commonly used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses..
