Touch Switch Module Features A touch sensor is a type of switch that needs to be touched by an object to operate. Touch sensors work completely similar to a switch. Note When this switch is touched, the output voltage will be HIGH, otherwise is LOW. Note The output current is very low (about 40 mA). If you want to connect a higher current device to this switch, you must add a relay or transistor to your circuit. Note There is a jumper on the board. If you change the status ...

CJMCU-0201 Double Touch Sensor Features A touch sensor is a type of switch that only has to be touched by an object to operate. Touch sensors work completely similar to a switch. This sensor has two separate pads and can be used as two separate switches. Note When this switch is subjected to touch, the output voltage will be HIGH, otherwise it is LOW. Note The output current is very low (about 40 mA). If you want to connect a higher current device to this switch, you must add a rela...

Heart Rate Pulse Sensor Features Heart Rate Pulse Sensor can be used to measure the heart rate and some related parameters such as cardiac arrhythmia (i.e., abnormal heart rhythm). If you touch this sensor with any area of your skin that is closest to the arteries (such as the finger or earlobe), the sensor detects blood in the arteries. Each time the heart beats, blood is pumped through the arteries, and the sensor detects the flow of blood and increases the output voltage. Note This sensor has an analog o...

VNH2SP30 Moster Motor Driver Module Features Today, speed and direction control of DC motors is very common. A Full-Bridge circuit is one of the simplest methods to control a DC motor. This module is a Full-Bridge motor driver with high output current tolerance.INA, INB and PWM pins are used for controlling the speed and direction of motor rotation. The CS pin is also the current sensor. This pin's output voltage changes 0.13V per 1A.The input voltage should be between 5.5 and 16V. Also, the maximum al...

Inductive Proximity Sensor LJ12A3-4-Z/BY Features A proximity sensor is a sensor able to detect the presence of nearby objects. The inductive proximity sensor LJ12A3-4-Z / BY has three pins, two of which are connected to a supply voltage of 6 to 36V. The output pin is PNP and NO (Normally Open). That is, it is normally Low and when it detects an object, it is HIGH. The detection distance is 4 mm and it can only detect metal objects such as copper, aluminum, iron, etc. Note Because the operatio...

APDS-9930 Ambient Light Sensor Features This module consists of ambient light , IR and proximity sensors. The detection distance is up to 100 mm. The APDS-9930 sensor measures the ambient light. This sensor can also detect 0.01 Lux brightness in the dark. It can also be used behind dark glass like a mobile screen. For example, it turns off the touch screen during voice calls when your ear is close to the screen.This sensor can be used to adjust the brightness of mobile backlight and the approp...

SW-520D Vibration Tilt Sensor Features The SW-520 sensor consists of two metal balls which switches as a trigger. When the switch is positioned horizontally, and when the sensor angle is less than 10°, the circuit is open (off state) and more than 10°, it is closed (on stated). But when the switch is positioned vertically, the circuit is open when the sensor angle is less than 45°, and close when the angle is more than 45°. To see exactly how this sensor works, read the datasheet. The SW-520D sensor is ...

TMP36 Temperature Sensor Features The TMP36 sensor is used to measure temperature from -40°C to +125°C and its tolerance threshold is +150°C. This sensor is calibrated directly on Celsius and its accuracy is 2°C. This sensor has an analog output. The output voltage changes linearly as the temperature changew. For example, the sensor output voltage is 0.75 volts at 25°C and 2.7 volts at 125°C.This sensor can be used in environmental control systems, thermal protection, fire alarms, CPU thermal m...

TLP281 4-Channel Opto-isolator IC Module Features Sometimes we need to separate the low-voltage section (microcontroller) from the high-voltage one in circuit in order to prevent noise and damage to the microcontroller. This module isolates the low-voltage section from the high-voltage section using TLP281-4 IC. This IC contains 4 LEDs (Light Emitting Diode). 4 high-voltage channels can be controlled by microcontroller using this IC.This module can also be used to turn on and off the servo motor and oth...
