This DC motor has an integrated transistor built in to the board, eliminating the need for a motor driver. Use PWM to control it for all your DIY project needs. It uses the 3 pin "gravity" interface saving lots of messy wiring.
Operating Voltage: 5V
Interface type: Gravity 3-pin dig..
This Gravity Analog 20A current sensor is based on the Hall current sensing principle. It can be used for AC or DC current measurement, has a wide voltage range, a small footprint, requires no soldering and has a high level of precision.We have added high-voltage isolation in the circuit design for ..
The Bright LED module is designed for some special applications requiring a very bright LED component as its light source. Compatible with DFRobot gravity 3-Pin interface, plug and play. Simply drive it directly with digital signal.Note: Do not stare at the LED in case of any eye damaging - this LED..
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 of atmospheric CO2 content to some extent results in global c..
DFRobot released its latest wide range Arduino infrared CO2 sensor, which effective range is up to 0~50000ppm. This sensor is based on non-dispersive infrared (NDIR) technology and has good selectivity and oxygen-free dependency. It integrates temperature compensation and support UART communication ..
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 temp..
This module is a self-locking switch. Press the button to turn it to the "on" state and press it again to turn it to the "off" state. The board has immersion gold plating and is compatible with the "gravity" 3-pin interface making it easy to connect to an Arduino I/O Expansion Shield.Specification O..
DFRobot’s Expansion Shield for Intel® Joule™ is a powerful add-on component to the Intel® Joule™ compute module with its carrier Expansion Board for Intel® Joule™. Other than what is originally supported by Intel® Joule™ and the expansion board, the expansion shield adds following features especiall..
The Hall Angle Sensor is a miniature 360 degree sensor which works based on the principle of the Hall effect. It is compatible with the DFRobot Gravity sensor interface, and works with a 5V DC power supply. The analog output is also 0~5V so it can work directly with Arduino.The Hall angle sensor wor..
The DFRobot Heart Rate Monitor Sensor is used to measure the electrical activity of the heart. This electrical activity can be charted as an ECG and output as an analog reading. An ECG signal can be extremely noisy so we have included an AD8232 chip on the PCB which will provide a clear signal from ..
This heart rate sensor is a thumb-sized heart rate monitor designed for Arduino microcontrollers.This sensor is a pulse sensor which is developed based on PPG (PhotoPlethysmoGraphy) techniques. This is a simple and low-cost optical technique that can be used to detect blood volume changing in the mi..
What sensor should you use when you need to measure temperature? Most people will think of a DS18B20 temperature sensor first, but this sensor is only capable of measuring temperatures up to 125C. In order to measure temperatures greater than 100C you will need something with a greater temperature r..
