This sensor takes a continuous reading of any obstacle and settles it at output in TTL form within 2ms. The sensor provides easy interface of 3-wire with power, ground and the output voltage. The sensor works on 5V input Features -Very Small in size -Less influence on the color of reflected objects, reflectivity -Industrial grade quality -Can detect colour difference from certain range -TTL output high whenever sensor senses a obstacle -Detecting distance of 3cm to 80cm -External control circuit unnecessary -Low cost -Has inbuilt lenses assembly and potentiometer to set range of the module -Output indication LED

It is a durable probe essential for outdoor use. This also comes with a green LED for directing users where to touch. The probe comes with a brass M18 x 1 nut for panel mounting. Since the body of the probe also forms the ground contact, the panel should be of non-conducting material to avoid ground loops. The 30cm cable with connector is provided for easy connection to the system microcontroller.

The DS1990A serial number IButton is a rugged data carrier that serves as an electronic registration number for automatic identification. Data is transferred serially through the 1-Wire protocol, which requires only a single data lead and a ground return. Every DS1990A is factory lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel iButton package is highly resistant to environmental hazards such as dirt, moisture, and shock. Its compact coin-shaped profile is selfaligning with mating receptacles, allowing the DS1990A to be used easily by human operators.
