The SparkFun Proximity Sensor Breakout is a simple IR presence and ambient light sensor utilizing the VCNL4040. This type of sensor is often seen in the automatic towel and soap dispensers or automatic faucets.

With the ability to detect objects qualitatively up to 20cm away, you will be able to detect if something is there and if it is closer or further away since the last reading.

Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.

The SparkFun Proximity Sensor Breakout is a great digital alternative to the popular analog-based Sharp sensors. The VCNL4040 has no dead zone and can read all the way up to the face of the sensor. This sensor also has an ambient light sensor built in it which is excellent if you need a digital light sensor for your next glitter cannon.

How to interface with Adjustable Infrared Sensor

This PBS 250v  Inductive 12mm NPN-NO Proximity Sensor Switch is a component widely used in the automatic control industry for detecting, controlling, and non-contact switching. When the proximity switch is close to some target object, it will send out the control signal.

When the metal approaches the near-proximity switch sensing area, and Eady Current is induced in the metal. Which in turn disturbs the magnetic field produced by the Inductive Proximity Sensor. This change is sensed by the sensor.

These inductive proximity switches can be non-contact, have no pressure, no spark quickly issued the electrical command. Accurately reflect the position and stroke movement mechanism. Positioning accuracy, operating frequency, service life. Easy to install and suitable for harsh environments.

This 8mm proximity sensor can detect a variety of metals, miniature size, long life, low price, shielded type installation, anti-interference ability, 1mm detection distance, used for precise positioning of moulds, precision machine tools, and robots.
