Product Description Proximity 3 Click Overview: Parallax speeds the process of Propeller 2 development through our partnership with MikroE, who has created a family of 850 Clicks for most I/O functions you may envision. Connect your Click boards to the Propeller 2 Evaluation Board or P2-EC Edge Breakout Breadboard using the #64008 P2 to MikroBus Click Adapter. Proximity 3 click is an intelligent proximity and light sensing device, which features the VCNL4200 sensor from Vishay – high sensitivity long distance proximity sensor (PS), ambient light sensor (ALS) and 940 nm IRED, all in one small package. With its smart sensing and light conditioning properties, the Proximity 3 click can be used in a wide range of applications: adjusting the brightness of the TFT screen depending on ambient light, turning off the TFT background light if it is covered, very accurate lux meters, reliable security sensors and so on. Proximity 3 click uses the VCNL4200 sensor, which combines matched 940 nm IR emitter and a photodiode for proximity measurement and ambient light sensing. VCNL4200 offers programmable measurement by utilizing the advanced signal processing techniques, allowing the sensor to operate in various conditions. Communication with the microcontroller is done via the I2C interface so that the host controller can set the measurement parameters and request results back from the sensor.
