Ir proximity sensor short range.

The working of any infrared sensor is governed by three laws. Optical wireless communication is done with ir data transmission for short range applications. Part gp2y0a41sk0f has an analog output that varies from 3 1v at 4cm to 0 3v at 30cm with a supply voltage betwee infrared proximity sensor short range sharp gp2y0a41sk0f sen 12728 sparkfun electronics. Sharp infrared short range proximity sensor digital 10cm sku.

Maximum range m 0 30. Infrared proximity sensor short range sharp gp2y0a41sk0f. An infrared sensor emits and or detects infrared radiation to sense its surroundings. Light detector 2pd infrared led and signal processing circuit short distance measuring type battery drive compatible operating power supply.

It works similarly to ultrasonic sensors though instead of using sonic waves ir is transmitted. Infrared proximity sensor short range sharp gp2y0a41sk0f sen 12728 13 95. This small digital distance sensor detects objects between 0 5 and 5 cm 0 2 and 2 away. Minimum range m 0 04.

In mobile phones an infrared ir proximity sensing module detects when the phone is held on the user s face during a voice call which can turn off the display. Packed in a small form factor with low power consumption this ir proximity sensor allows for continuous distance reading with a range of 10cm to 80cm. I am quadriparetic so handsfree is always good for me. After working with the smartthings motion sensor i can see a use for a very short range proximity sensor to create a touchless switch.

Typical update rate hz 60. Wavelength light nm. Planck s radiation law stephen boltzmann law and wien s displacement law. 2 7 to 6 2 v 0 3 to 7 10 to 60.

These include a wall switch faucet soap dispenser and a trash can where. This requires short range proximity sensing. Infrared proximity sensor made by sharp. Infrared proximity sensors consist of an ir led that emits and a light detector for detection of reflection.

With its quick response time small size low current draw and short minimum sensing distance this sensor is a. Resolution mm accuracy 1. They all use proximity sensors at a range of two to four inches.
