YugenFlow v2: Compact, easy-to-use, low-power, bi-directional, privacy-respecting thermal detection sensor

YugenFlow v2 is a compact, easy-to-use, low-power smart thermal sensor board that uses low-resolution thermal sensors to detect the presence of people and determine whether they are moving in a given direction. The sensor determines the direction along an axis, the physical meaning of which depends on how the sensor is mounted. YugenFlow does not require motion to detect presence, but can use it to determine orientation. The sensor can detect and "track" up to two people simultaneously from a distance of approximately 40 centimeters. It's also very fast.

syzygy-epc901: SYZYGY and EPC901 CCD + 50MSps ADC

The EPC901 is a 1024x1 CCD sensor capable of providing 50MHz pixel output. It outputs analog voltage from the CCD element. The author paired it with a 50MSps ADC on a SYZYGY board. The datasheet says it can run up to 50k fps. External I/O is provided via optocouplers to facilitate connection to external trigger sources such as motion controllers. This board will assist in conducting experiments on the new PnP platform. Objects can be moved through the line scanner to capture the position of the photo.​
