SR-602 Small Human Infrared Sensing Module Sensitivity High Pyroelectric Probe Inductive Switch SensorItem NO.: SR602

SR-602 Pyroelectric Body Infrared Sensor Module

Working Parameters:

● Model: SR-602

● Sensing distance: maximum 5M, 0-3.5M recommended

● Output: high level, H=3.3V, L=0V

● Power supply voltage: 3.3-15V

● Quiescent current: 20uA

Characteristics And Purpose:

This module has high sensitivity, fast response speed, small static power consumption, compact size, and easy installation. The lens has been installed, the array of pins has been welded, and the power supply is equipped. No debugging is required. It can be used for human body induction lamp, alarm, security, on-demand camera for access control, automatic equipment for agriculture, forestry and mining, etc.

Key Points:

1. The output high level time of this product is adjustable, from 2.5 seconds to 1 hour. The factory set output time is 2.5 seconds. If you need to change it, you can change a chip resistor. For the resistance value corresponding to the typical delay time, please refer to the relevant table below.

2. Blocking time, 2 seconds, non adjustable.

3. The factory definition is repeatable and cannot be changed.

4. The power supply voltage of this module is 3.3V to 15V, and the limit voltage is 2.8V to 18V.

5. The module output timing is: after power on, the module outputs high level for 2 seconds, then turns to low level, and enters the standby state. If the delay time is changed, the time for the module to output high level will increase accordingly after power on, which can be understood as the starting time for the module to enter the normal working state will increase after power on.

6. After the photosensitive parts are installed, they do not work during the day, work at night, do not install photosensitive components, and work all day (by default, they are not installed with photosensitive parts).

7. This module is very sensitive. Pay attention to the installation position and try to avoid the heat source and radiation source (air outlet/direct sunlight)

8. The sensitivity of this module is adjustable, so a chip resistor is required. Please refer to the relevant tables below for details.

9. When using 220V ordinary soldering iron for welding, the power supply must be unplugged before welding. It is recommended to use 24V low-voltage soldering iron.

10. Please read the reference circuit diagram below if you want to connect the MCU and the lamp.
