|
Notes
|
The trigger mode can be repeated, in other words, after sensing the high or low level of the output, if someone is move around in its sensing range within the delay period, its output will remain the output valid condition until the person leaves the detection range. After the delay period, the output will change. In general, if the output connect with the LED light when someone always moving in the detection range, the activity light will remain on. On the contrary, when the person leaves the detection range, the light will remain off after the delay period. The light will be illuminated again after the 1.8 seconds delay period when someone enters in the detection range
|
Packaging
|
This PIR-4A has installed lens and additional pins (customer can weld the pin horizontally or vertically according to their own situations). This module has high sensitivity, low standby power consumption, small size and easy installation. The module can be used without debugging
|
Product level description
|
Output high level version
|
When someone enters the detection range, the module OUT will output a high level of 3V (almost all human body sensing modules output are the same), the high level version of the output current is small, the maximum does not exceed 10ma, so it can not directly drive the LED lighting equipment. The output can be directly connected to the MCU, relay module, optocoupler etc
|
Output low level version
|
When the someone enters the detection range, the module OUT will output a low level of 0V, and it allows output of current within 0.5A to 1A, which can directly connected with a high power load ( Less than 18W), such as 12V LED lighting equipment, relays. It also can directly control other electronic equipment and can connect with MCU relay module
