Learn about one of the latest sensor technologies for touchless faucets and why it reigns superior over standard infrared.

Touchless sensor faucets are slowly but surely taking over the world — yet not all sensors are created equal. Compared to infrared sensors, PSD (Position Sensitive Detector) is a superior sensor technology that ensures Oras touchless faucets work as precisely as possible.

 Here’s a quick comparison of PSD vs infrared sensors and how they work:

 

Infrared sensors

With infrared sensors, detection is based on reflected light intensity. When the target reflects enough light back to the receiver the faucet is activated.

 The drawback with infrared is that variations in skin colour, clothing, light and reflections can cause an imprecise reaction to hand movements. For example, dark surfaces can affect reflection and cause late detection, and conversely bright surfaces (mirrors, for example) can cause early detection.

 And where late detection can result in a negative user experience, early detection can lead to unnecessary water waste.

PSD sensors

The accuracy of PSD sensor detection is 10 times higher than infrared detection. PSD senses the precise distance of an object in relation to the infrared eye and reduces false actuation due to variations in clothing, skin colour, light and reflections.

In other words, hand movement is detected precisely when the infrared is reflected in the sensor area, and water flow will stop as soon as the user is not detected in the sensor area.

Today, the majority of Oras touchless faucets are equipped with both PSD and Bluetooth technology, which allows you to adjust and keep track of the faucet through an app. Whether your customers are private homeowners or running larger commercial projects, you can help them understand the difference between standard infrared and PSD and how to choose reliable touchless faucets that can keep their bathrooms running smoothly.
