US-100 Distance Sensor Features The US-100 is an ultrasonic transmitter and receiver module used to measure distance. The sensor operation is very simple. You only need to measure the return time of ultrasonic waves in order to measure the distance. Then you can divide this time by 2 and multiplied by the sound speed. The sensor measuring range is about 2 to 450 cm. Note The US-100 module has 2 different communication protocol. Method 1: use serial communication Method 2: use Trigger and Echo (similar to ...

MC-38 Magnetic Sensor Anti Theft Alarm The MC38 is a magnetic switch. When a magnet (the wireless part of the sensor) approaches it, the sensor acts like a switch and the two pins are connected.This sensor is used to detect closed or open doors, windows and alarm systems. Note Magnetic switches are available in two types, Normally Open and Normally Close. In this tutorial we use a Normally Open switch that closes as the magnet approaches the sensor (the two sensor pins are connected). ...

RCWL-0516 Microwave Radar Sensor Features The RCWL-0516 microwave radar motion detection sensor is used to detect motion at a maximum distance of 9 meters. The viewing angle of this module is about 270 degrees and it has a digital output. You can install a photocell sensor on this module. Note The RCWL-0516 module does not work properly at a distance less than 20 cm. Note This module can measure a maximum distance of 7 meters by default; but you can adjust distance by placing a resistor behind the board. No...

WS2812 - LED RGB Module Features This is a breakout board for the WS2812B RGB LED. The WS2812B (or NeoPixel) is actually an RGB LED with a WS2811 built right into the LED! This module has a 5mm RGB LED on it, which has the ability to create 16777216 colors. WS2812 RGB Module Pinout This module has 4 pins: VCC: Module power supply - 5 V GND: Ground DI: Input data from the previous micro or module DO: Output data to next moduleYou can see pinout of this module in t...

Load Cell Sensor Features Load cells are electronic sensors that are able to measure weight and force. The body is usually made of aluminum, alloy steel, or stainless steel which makes it very sturdy but also minimally elastic. This elasticity gives rise to the term "spring element", referring to the body of the load cell. When force is exerted on the load cell, the spring element is slightly deformed, and unless overloaded, always returns to its original shape. Load cell capacity is equal to the maximum am...

NEO-6M GPS Module Features The GY-NEO-6M module is an advanced GPS module that supports UART communication protocol with active antenna. You can interface this module easily with any microcontroller. This module has a rechargeable battery and can also be connected directly to a computer using a USB to TTL converter. This module can receive information and then calculate the geographical position with very high accuracy and fast speed. In addition to supporting BeiDou, Galileo, GLONASS, GPS / QZSS, the modu...

L298N DC Motor Driver Feature L298N module is used to drive DC motors with a current of less than 2 amps. This module is easy to use. It contains convenient filter circuit and have access to inputs and outputs via pin headers and terminals. The L298N is a dual full-bridge motor driver that allows two DC motors to be connected simultaneously. Note The L298N motor controller follows the H-bridge configuration, so it can be used to drive stepper motors too. This driver needs a logic voltage supply to drive t...

GP2Y1010AU0F Dust Module Features The GP2Y1010AU0F is an optical air quality sensor, designed to sense dust particles. An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems. You can download the datasheet of this module here.[wpdm_package id='18191'] ...

MQ-2 Smoke Gas Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kinds of gas combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is necessary. Gas sensor is an indoor module and is used at room temperature. The MQ-2 sensor is suitable for the detection of butane, methane, alcoholic, LPG and smoke. It is also sensitive to ignition and combustion of gases. Note Afte...

PC817 Optocoupler Module Features An Optocoupler, is an electronic component that interconnects two separate electrical circuits by means of a light sensitive optical interface.There is a is a light emitting diode with a phototransistor inside the optocouplers, both of them are isolated from the external environment of the optocoupler; This means that the internal phototransistor can only receive light emitted by the internal light emitting diode. The phototransistor base is stimulated by light receive...
