● Multifunctional PIR sensor stair light controller features daylight sensor, 2 groups different SPI(TTL) signal output.
● Group 1 SPI signal output to realize white light step or color light step control.       
Default is white light step control, use with ES-F step sub-controller to realize the step control of each step white light strip.
● Group 2 SPI signal output for color light flow control.
● Color light step or color light flow output, can drive 18 kinds of IC digital RGB LED strip, can set IC type and R/G/B order. 
Compatible ICs: TM1804,TM1812,UCS1903,UCS1909,UCS1912,UCS2903,UCS2909,UCS2912,WS2811WS2812, TM1829, TM1914A, SM16714D, SM16703P.GW6205, GS8206,UCS5603, UCS2603, 
●Easy operation with OLED display and 3 buttons.
●Built-in multiple color mode, speed and brightness 1-8 grade adjustable.
●Use with two PIR body sensor heads (standard), or when precise sensing is required,  the optional infrared reflector kit ES-T is available
