Precautions to protect the reliability and long life operation, avoid temperatures outside the relevant provisions of the outside world (outdoor) conditions, although the proximity sensor for water structure, if fitted cover use, rendering water and water-capacitive cutting oil leaching to, you can better improve the reliability and service life. Please also avoid chemicals in there, especially in the use of alkali, acid, nitric acid, Ming acid, hot concentrated sulfuric acid and other climates.

Red: power high pick 4.5-5V

Yellow: connect microcontroller, TTL-level output to the microcontroller

Green: Connect GND 0V supply low
