Can this be used as a cliff sensor
I am building a wheeled robot. Planning using some Grove sensors to monitor environmental conditions. As the robot is going to be 'wondering' around I need a cliff sensor to prevent the robot from falling down stairs etc. Would this sensor be suitable? If not can you recommend a sensor that would be appropriate? Thank you

  • Yep this would be ideal. Cliff sensors are just IR distance sensors.

This IR Distance Interrupter features a high-sensitivity RFR-359F photoreflector to perform distance detection function. The photoreflector consists of a GaAs infared light emitting diode and a silicon planar phototransistor. When the infrared light emitted by the emitter gets reflected on a surface that blocked it, the phototransistor can pick up the signal for distance calculation. This module is panel mounted so that you can easily implement it on the surface of robots or other projects without wiring clutter. Also a potentiometer for adjustment and an indicator LED are arranged on the back for easy and clear use. 


  • High sensitivity photoreflector
  • Lightweight and compact
  • Panel mount design for clean and tidy implementation
  • Clear HID design: adjustment potentiometer and indicator LED

Application Ideas

  • Wanderer robots
  • RPM gauges
  • Approximation detection
