Working current : < 20mA
Operating temperature range: -10 ° C ~ 70 ° C
Detection resolution: 10%
Interface type: analog signal output
Size: 24mm x 21mm
Weight: 3g
Interface definition
S:Signal output
:Power supply (VCC)
-:Ground (GND)
Instructions
working principle
The gradation sensor comprises a white high-brightness light-emitting diode and a photoresistor Since the light returned by the light-emitting diode on different gradation papers is different, the photoresistor receives the returned light, and the photoresistor is different according to the intensity of the light The resistance values are also different, thereby realizing the test of the gray value
Programming principle
The gray level sensor has three pins, which are the power supply positive Vcc, the power supply ground GND, and the signal end S In actual use, the sensor can be directly connected to the analog interface of the Arduino controller, for example, the analog port A0, after the Arduino is powered on, The sensor white highlight LED lights up, the sensor button is placed on different gray paper, the data is read by the AD conversion of the Arduino controller, and then the measured analog quantity is printed through the serial port
Connection diagram
The S port is connected to the analog input pin of the controller Connect 5V and GND to the 5V and GND of the power supply, respectively
 
Sample program
Connect the grayscale sensor to the Arduino UNO controller according to the program and observe the value of the serial port output under different gray values
Void setup()
{
     Serialbegin(9600); //Open the serial port and set the serial port baud rate to 9600bps
}
Void loop()
{
     Int val;
     Val=analogRead(0); //Connect the grayscale sensor to the analog interface0
     Serialprint("Grayscale is ");//Print the analog value read through the serial port
     Serialprintln(val, DEC); / / print the analog value read through the serial port
     Delay(100);
}
Program effect
When you detect different gray values, feedback back to the measured value at this time As shown in the figure below, this figure is a schematic diagram of the data returned by the serial port when the gray level sensor detects 85% of the gray value

1 This 5V laser head very easy to use, you can use Arduino control, do controllable laser pointer, theft detection, etc interesting application devices
(2) Whenever the laser can not point to themselves or others eyes, even if the case is closed the laser will have to open the possibility of error
3, the laser is not a toy, do not give children, mental insufficiency, for people who do not understand the use of the laser characteristics, in this case, can easily lead to injury
4, the use of lasers should wear special goggles, for the invisible laser, this point is particularly important
5, the laser can not shine in vehicles, aircraft and other transport vehicles someone

Knock Sensor Module for Arduino
 
Disclaimer:
100% brand new and high quality
Knock sensor module and a digital 13 interface, built-in LED build a simple circuit to produce percussion flasher Interface comes with digital LED, will knock sensor connected digital 3 interface, when percussion sensor senses measure to percussive signals, LED flashing light
Size: 30x18x6mm (approx)
Routines source code:
int Led = 13;// define LED Interface
int Shock = 3;// define the percussion Sensor Interface
int val;// define numeric variables val
void setup ()
{
pinMode (Led, OUTPUT) ;// define LED as output interface
pinMode (Shock, INPUT) ;// define knock sensor output interface
}
void loop ()
{
val = digitalRead (Shock) ;// read digital interface is assigned a value of 3 val
if (val == HIGH) // When the percussion when the sensor detects a signal, LED flashes
{
digitalWrite(Led, LOW);
}
else
{
digitalWrite(Led, HIGH);
}
}
