This is what is known as a Real Time Clock (RTC) module and can be used with any Arduino so that it can tell time. The Arduino does not have a RTC on board and therefore can not tell time for an extended period of time with any accuracy. When the Arduino...

This is a digital temperature and humidity sensor module that works with all of the Arduino micro-controllers. Because it is a digital sensor it only necessitates 3 connections, Vcc, GND, and a digital pin for data output. With this sensor you get two...

This is an Arduino Compatible Ultrasonic sensor, it can be used to measure the distance from the sensor to other objects around it. These types of sensors are used on robots for collision avoidance and guidance or as trip sensors for alarm systems or...

L3G4200D is a 3 axis gyroscope, providing you with very high resolution (16 bit) measurements at up to 2000 degrees per second (dps).   The gyroscope measures how much the device is rotating around all three axis, the range is user selectable and so...
