Adjustable Infrared 80cm Sumo Sensor

If you are looking for an obstacle sensor with an 80 cm range, you should be on the right page :) This is a contactless obstacle detection digital sensor. And with its compact size, it is perfect for mini-sumo robots and small robot projects. It can detect an object within 80 cm (based on detecting area and surface, it can be up to 110cm!) range.

Interface with microcontroller is straightforward as it supports power from 5.0V, and requires to pull up resistor which can be enabled from Arduino code, just add in [pinMode(sensorpin, INPUT_PULLUP)] under the void setup(), simple and straightforward.

Possible Projects:

• Mini Sumo Robots (We suggest strongly!)
• Maze Robots
• Obstacle Avoiding Robots

Features/Spec:

• Works from 4.5V to 5.5V and will draw less than 25mA
• Output type: NPN output, require additional Pull up resistor
• Small multiturn POT (Potentiometer) to adjust detection distance
• At the backside, it has a red LED for detection status. Light up when the sensor detects an obstacle
• It comes with a 30cm stranded wire.
• Cable Definition:
  • Red: Positive power, 4.5 to 5.5VDC
  • Black: GND
  • White: Signal Out (NPN)
• Response time less than 2ms
• Pointing angle: 15 degree
• Working temperature: -25 degree ~ + 55 degree
• Standard sensing object: sunlight 10000LX following
• Incandescent 3000LX following
• Case Material: Plastic
• Reverse Polarity Protection for the VCC and GND
• Size: 31 x 25 x 13mm

• 1 x Adjustable Infrared 80cm Sumo Sensor
