Optical Connector

Easy connect for Optical Infrared Water Level Sensors.

Feature List

• Easy to connect Optical Infrared Water Level Sensor.
• 390Ω pull-up and 4.7kΩ pull-down to drive the signal.
• Supports two gpio lines D1 and D2.
• 31.1mm x 17mm 4-Wire.
• 25.89mm x 15.4mm 3-Wire.

What type of Optical Infrared Water Level Sensor connects to the Optical Connector?

3-Wire

4-Wire

So how do Optical Infrared Water Level Sensors work?

So why do I want to use them over traditional float switches?

• High precision level control.
• Easy mounting method with locking nut
• Highly compact.
• No moving parts.
• Highly durable
• Waterproof.
• Low current 3-Wire 12mA or 4-Wire 15mA.

Let's connect an Optical Infrared Water Level Sensor on pin [14] of the IO Expander and read the [i]nput.

Now let's place the sensor in water and read the [i]nput again.

It work's just like a float switch! But this highly sensitive device can also be read as an analog input.

Let's read it out of the water, half way, and then completely immersed.

As the water level starts to cover more of the prism the read voltage drops. So this sensor is hightly accurate and can be read either as digital or analog.
