In stock

SKU: 1496178

1. DC-INPUT: working voltage or input supply voltage (range is DC 3V~12V)
2. VOUT: signal output pin. Output: High-level signal 3V; Standby 0V。
Voutput can be as same as DC-Input by adding some components
3. Delay time adjustment: the default delay time is 10s, which can be adjusted by changing the resistor

SB412A is the latest digital sensor module that is based on AM412 digital sensor. It only contains a
Fresnel lens, PCB, and a few resistance.

Due to the high sensitivity of the PIR sensor device, it is not recommended to use the module
in the following or similar conditions.
A) in rapid environmental changes
B) in strong shock or vibration
C) in a place where there is obstructing material (eg. glass) through which IR cannot pass
within the detection area.
D) exposed to direct sunlight
E) exposed to direct wind from a heater or air condition

Note: For more technical details go through Datasheet in the attachment section
