The IR Sense 3 Click Board™ is the infrared sensor Click Board™, designed to be used for short-range IR sensing applications. Unlike other pyroelectric sensors, it is able to sense environmental heat changes up to 1m, even through glass.
The IR Sense 3 Click Board™ utilises a human approach detection algorithm that makes perfectly suited for many human presence detection applications. A programmable interrupt engine simplifies the software development and saves MCU cycles, that would be otherwise wasted on polling. The ability to sense IR through the glass allows an unconstrained design of the final product.
