Obstacle Sensor

Sharp GP2D12 IR Range Sensor - 10cm to 80cm

Infrared rangefinder 10cm (~4") to 80cm (~30")
• Analog Interface
• Operating supply voltage is 4.5V-5.5V
• Suitable to use as a sensor for a obstacle robot

Read the distance of the object in front of your robot. The Sharp GP2D12 IR Range Sensor takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 10cm (~4") to 80cm (~30"). The interface is 3-wire with power, ground and output.

Micro beam sensors EX-D200E can used to sense the object. This sensor have built-in amplifier. Selecting output operation by connecting control wire will make it dark-On or light-On. The maximum sensing range is up to 200mm.Its need 12V voltage supply.
