On a digital smart integrated circuit chip, a digital smart integrated circuit converts a signal into a 15-bit ADC Digital signal, when the PIR signal exceeds the selected digital threshold, there will be a timed REL level input Out. The OEN enable can be used to automatically control the REL output or through the light sensor. Sensitivity and time. The inter-parameter is set by a resistor, corresponding to the corresponding value, and its voltage is converted to have 7 bits. The digital threshold of the resolution. All signal processing is done on the chip.
