The Proximity 2 Click Board™ is an accessory board featured with a tiny footprint MAX44000 IC. The chip features an integrated ambient light sensor as well as proximity sensor. It comprises of a group of photodiodes that work by converting light into current. The internal circuitry then converts the resulting current into a digital value. Proximity 2 Click Board™ has an on-board ambient light sensor with a dynamic range of 0.03 to 65.535 lux. The IR proximity detector, with a sensing range of approximately 12cm, is matched with an integrated IR LED driver. Proximity 2 Click Board™ communicates to the target board microcontroller via MikroBUS I2C (SCL, SDA), and INT lines. All readings are available on an I2C communication bus. It also has a programmable interrupt pin. Proximity 2 Click Board™ supports a 3.3V power supply only.
Due to its small size, it is an ideal choice for industrial sensors, presence detection, tablet PC applications, and smartphones.
