For passive infrared PIR motion detection, sp015 integrates infrared signal analog-to-digital converter, band-pass filter and digital threshold ratio
Trigger device processing logic such as comparator, LED signal output, infrared signal output rel, sensitivity setting, delay setting, on-chip oscillator
And band gap reference and other intelligent modules, covering all the necessary functions of single PIR motion detection
● sp015 input interface is directly connected with traditional PIR sensor through high resistance differential input, and PIR signal is converted into 16 through analog-to-digital converter.
The bit data code is compared with the threshold value set by sensitivity in digital domain. If it is greater than the threshold value, the LED output is valid. Simultaneous digital comparator
The output signal is sent to the trigger event processing logic. If certain trigger conditions are met, the rel is triggered for a valid period of time, which is delayed by
