Sr-602 hot release human body infrared sensor module use instructions
● Parameters of work:
Thermoelectric human infrared sensor module, model: sr-602
Induction distance: up to 5 m recommended 0-3.5 m.
Output: high level, h 3.3v, l 0v
Dc: 3.3v-15v
Static current: 20ua

Characteristics and uses:
This module is sensitive, fast response speed, small static power consumption, small volume, easy to installl, installled.
Lens, soldered needle, power supply, no debugging.Can be used for human body induction lamp, alarm, security,
Door shut-up camera, agro-forestry mining automatic equipment, etc.

Highlights:
-the output time of this product is adjustable, from 2.5 seconds to 1 hour, and the output time set for the factory is 2.5 seconds. if you need to change, you can change a patch resistor.Please read the relevant table below for resistance values corresponding to typical delay time.
-closure time, 2 seconds, not adjustable.
-out of factory is defined as repeatable trigger and cannot be changed.
-the supply voltage of this module is 3.3 v to 15v and the limit voltage is 2.8 v to 18v.
-module output sequence is: output high level 2 seconds after electricity, then becomes low level, into standby state.If the delay time is changed, the output time of the module will increase accordingly, and it can be understood that the starting time of the module into normal working condition will increase.
-after installling a photosensitive element, it will not work during the day, work at night, do not installl a photosensitive element, work all day (defaultly without a photosensitive element). .
-this module is sensitive, sensitive to installlation location, avoiding thermal source sources as far as possible (air outlet/direct sunlight)
-the sensitivity of this module is adjustable and a patch resistor needs to be changed.Please refer to the relevant table below for details.
-when welding with 220v common soldering iron, it is necessary to unplug the power before welding. it is recommended that 24v low pressure soldering iron, such as domestic white light 936, be used.
-if you have a single chip computer and a light, please read the reference circuit diagram b
