SL116A Long Distance Motion Detecting Micro Module
Overview
This auto-control product SL116A is based on the infrared line technology, with high sensitivity, reliability and ultra low-power working mode. It is widely used in all kinds of auto-detecting electrical equipment, particularly dry battery supplied products.
Features
■ Full-automatic Sensing: When people enter into the PIR detection range, the module will output high level. Otherwise, it will turn off high level output after delay time and output low level instead.
■ Built-in Processing Chip: The module has a built-in analog-digital processing IC. The IC works with the PIR sensor, shielding RFI in the shell. It makes the product more steady.
■ Built-in Analog-digital Chip: The module has a 16 bit ADC, which converts the digital signal generated by sensitive element into analog signal. And the special filter will efficiently filter all kinds of low and high frequency noise interference.
■ Triggering: When the value of infrared signal detected by PIR sensor exceed the internal triggering threshold, an impulse will be generated, causing the internal chip record this signal. If the triggering signals are received continuously, the module will output high-level until the last effective triggering finish the delay time.
■ Sensing Blocking Time(Default: 2.5s):The module can set a blocking time period after every output. During this period, the sensor will
refuse any kind of sensing signal. The interval work between sensing output time and blocking time can be used to interval detecting products. Meanwhile, this function will effectively restrict the interference in the process of load switching.
■ Optional Working Voltage: DC3-18V。
■ Micro-power Consumption: When DC=3V, Quiescent current ≤ 20uA.
■ High Level Signal Output: Convenient to connect with all kinds of circuit.
■ Long Detecting Range: 8m for small lens and 13m for big lens.
