DHT21/AM2301 Temperature and Humidity Sensor Features The AM2301 / DHT21 temperature and humidity sensor consists of two sensors: A capacitive humidity sensor and a thermistor. This sensor transmits data using a single digital pin, so it can communicate with the microcontroller using only one digital pin. The sampling frequency is 0.5Hz, which means that you can get new data every two seconds. DHT21/AM2301 Temperature and Humidity Sensor Pinout This Module has 3 w...

TTP224 Capacitive Touch Sensor Module Features This 4 Channel Capacitive Touch Sensor Module uses the TTP224 IC and is actually a combination of 4 capacitive touch sensors. This module has 4 outputs, by touching each button from 1 to 4, the corresponding output will be High. There are also 4 LEDs on the module that will turn on by touching each button. TTP224 Capacitive Touch Sensor Module Pinout This module has 12 pins and 4 touch buttons:6 pins on the Right:OUT1: ...

KY-039 Heartbeat Sensor Module Features The KY-039 heartbeat sensor module can be used to detect the heartbeat signal using finger. This sensor has an analog output. By placing your finger on the module, you can see the heartbeat signal through the analog output pin. KY-039 Heartbeat Sensor Module Pinout This module has 3 pins:S: Analog output signalVCC: Module power supply – 5VGND: GroundYou can see the pinout of this module here. ...

HW-M10 Microwave Sensor Module Features The HW-M10 microwave sensor module is very accurate and widely used for motion detection in alarm and security systems. This module, like the PIR module, can detect any movement. The only difference is that instead of using radiation emitted by or reflected from objects, it uses microwave Doppler radar technology. This module has a digital output that is normally Low and becomes High (3.3V) if it detects motion and remains High for 2 to 3 seconds. ...

MPR121 Capacitive Touch Sensor Features The MPR121 capacitive touch sensor module is a high-precision touch sensor. This module has 12 touch buttons and supports I2C communication and can be easily interfaced with any microcontroller. There is no regulator on the board, so the supply voltage should be between 1.7 to 3.6VDC. MPR121 Capacitive Touch Sensor Pinout This module has 18 pins:6 Pins on the left:VCC: Module power supply – 3.3VIRQ: Interrupt outputSCL: Se...

EMG Muscular Signal Sensor Features In medical research, measuring the activity, contraction and expansion of muscles is important. The EMG muscle sensor measures the muscle activity and produces a signal to show the amount of expansion and contraction. Therefore, the output depends on the amount of activity in the selected muscle. 3 Green, red and yellow electrodes connect to the module for transmitting electrical signals from the muscle motion. Features: Small Form Factor Specially Designed for Micr...

EasyDriver Stepper Motor Features If you use a stepper motor in your projects, you will definitely need a controller for that. EasyDriver is a type of driver that controls stepper motors.

This module can be used to control bipolar motors.Features;Allowable continuous current: 0.750AMaximum allowable current: 0.850AMaximum allowable voltage: 30VThermal protectionCrossover-Current ProtectionPotentiometer included to limit the current Note It can operate bipolar ...

BYGH403 1.65A Stepper Motor Features Stepper motors are one of the most widely used motors in robotics and electronics. These motors are actually the same as DC motors that move in discrete steps. They have multiple coils called "phases". By supplying each phase in sequence, the motor will rotate one step (the angle of each step for each motor is specified in its datasheet). with controlling these pulses precisely, you can achieve very precise speed control.Applications:CNC3D printersInkjet printersSca...
