Light Dependent Resistor (LDR) Module Description and Working Principle As widely known, voice-controlled lights in hallways often include an additional sensor known as a photoresistor or Light Dependent Resistor (LDR). The LDR, typically made of cadmium sulfide (CdS), is a variable resistor that changes...

The tilt switch module, also known as a ball switch or steel ball switch, is essentially a type of vibration switch. It operates on the principle of a rolling ball making or breaking contact with conducting pins, thereby controlling the circuit's connection or disconnection....

The DS1307 clock module is a low-power, real-time clock (RTC) chip with 56 bytes of non-volatile RAM. It transmits addresses and data through a two-wire bidirectional serial bus. The chip provides information on seconds, minutes, and hours, and automatically adjusts for the number of...

The DS18B20 Temperature Sensor is a digital temperature sensor that provides 9- to 12-bit digital temperature measurements and has an alarm function with non-volatile, user-programmable upper and lower trigger points.Communication between sensor and microcontroller:The DS18B20 sensor communicates via a bus that requires only one...

This is game joystick module for Arduino.Lots of robot projects need joystick. This module provides an affordable solution to that.Simply connect to two analog inputs, the robot is at your commands with X, Y control. It also has a switch that is connected to...

The sensor is based on a potentiometer. A potentiometer is also known as a variable resistor. It is a perfect demonstration of a variable voltage divider circuit. Its voltage can be subdivided into 1023, easy to be connected to Arduino with our sensor shield.Combined...

This sound sensor is typically used in detecting the loudness in ambient environment.You can use it to make interactive circuits such as a voice-operated switch.The sound sensitivity can be adjusted by the potentiometer. The sensor comes with a fixed hole, easy for fixation on...

Crash sensor, also known as a snap-action switch, is an electric switch that is actuated by very little physical force.It is a digital on-off input module necessary for elementary electronics.By programming, it can be used for the light, sound device, key functions of LCD...

The EASY Plug Push-button module is a tidy little design that lets you control a DC power source using an everyday tactile button.This basic application module is widely applied to Arduino, and Raspberry Pi platforms.When the button is pressed, it outputs HIGH level signal;...

The tilt-switch twig is the equivalent of a button, and is used as a digital input. Inside the tilt switch is a ball that make contact with the pins when the case is upright. Tilt the case over and the balls don't touch, thus...

The flame sensor can be used to detect fire or other wavelength at 760nm ~1100nm light.In the fire-fighting robot game, the flame plays an important role in the probe, which can be used as the robot's eyes to find fire source.The potentiometer on the...

The knock sensor is mainly composed of SW-280 vibration switch, which is an inductive proximity switch.It is an electronic switch that transmits the sensing result to the circuit device and induces the circuit to start working when the vibration force is induced.The module comes...

The Line Tracking Sensor can tell white from in black or black from white accurately.The single line-tracking signal provides a stable output signal TTL for a more accurate and more stable line.The working principle is simple, using infrared light's different reflectivity for different color,...

EASY plug Steam Sensor needs to be used with the EASY plug Control board V2.0control board.The module is connected to the analog input interface with only one line, which is very easy and convenient. Vapor Sensor is an analog sensor and can make a...

FINGER is a fingerprint recognition sensor designed to provide reliable and convenient biometric fingerprint recognition capabilities. It features the integrated FPC1020A capacitive fingerprint recognition module, which enables functions such as multi-fingerprint enrollment, image processing, feature extraction, fingerprint matching, and searching.Utilizing the UART communication protocol, FINGER...
