INTRODUCTION We can divide temperature measurement in to two types: contact and non-contact. Contact measurement can only accurately measure temperature when the testing object and the sensor reach thermal equilibrium. This can mean...

Wave your hands and light turns on. Can you believe this magic turns into reality? This interactive sensor designed by DFRobot offers touchless gesture sensing, which means you can issue orders simply with a swipe of your hand!...

Romeo BLE Quad is an arduino compatible robot controller based on STM32 ARM chip. It inherits all features from the Bluno M3 , including wireless programming support, wireless communication between iOS/Android apps and remote control....

FIT0502(Stereo Enclosed Speaker) is a new passive speaker with JST PH2.0 interface. It is a perfect option for any DIY audio project which requires an 8 ohm impedance and 3W power. The suitable size and screw holes make it to be mounted....

What is a stepper motor? Stepper motor is a brushless DC electric motor that divides a full rotation into a number of equal steps The motor's position can then be commanded to move and hold at one of these steps. How to control a stepper...

This is the DFRobot TT Micro DC geared motor with encoder. It is a motor with a 120:1 gearbox and an integrated quadrature encoder that provides a resolution of 16 pulse single per round giving a maximum output of 1920 within one round....

An ultrasonic sensor measures distance by calculating the time difference between sending a signal and receiving an echo from an object. It uses echolocation to measure distances, just like a bat. The URM07 is an ultra low-power sensor....

Most ultrasonic distance sensors aren't waterproof which can be a problem if you need your project to withstand the elements outdoors. No need to worry any more! We have developed waterproof ultrasonic distance sensors with a waterproof...

WRTnode2P Devboard is a minimal standard interface module, delightful price, comprehensive software support, a wealth of documents and communities, good looking, texture, to I.o.T new era . SPECIFICATION Minimal WiFi & Linux Module in...

BME280 is an environmental sensor that integrates onboard temperature sensor, humidity sensor and barometer. The sensor is of high precision, multiple functions, and small size etc. It provides both SPI and I2C interfaces, which make it...

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...

Gravity: UART & I2C NFC Module adopts NXP PN532, a highly integrated NFC communication controller, which supports various types of NFC smart cards or tags like the commonly used MIFARE Classic series and NTAG series in the market. Apart...
