JS40F Digital Distance Sensor

Sensor Features

• Reflective type infrared (IR) sensor that rely on beam reflection of front object.
• Works between 3.3V to 5V. At 5V sensor draws 15mA.
• Has a reverse polarity protection between voltage inputs (Power & GND)
• No manual setting for distance decrease.
• At backside, it has red led for detection status.
• Comes with 15cm stranded wire.

Dimensions & Weight

• 17.7mm Length x 11.5mm Width x 12.6mm Height
• Only 4 grams weight. (Including cables)

Example Arduino Sketch:

int Sensor1=5; // Digital sensor connected to D5

int value; // We define variable for storing sensor output.

void setup() {

pinMode(Sensor1, INPUT); // Sensor1 is declared as input

Serial.begin(9600); // Serial communication started with 9600 bits per second.

}

void loop() {

value=digitalRead(Sensor1); // Sensor is read digitally and reflected to value.

Serial.print("Sensor Output: "); //IT will write Sensor Output to Serial Monitor Screen.

Serial.println(value); // It will write value variable raw value (0 or 1)

delay(100); // We added 100ms Delay for more balanced readings.
