Hot selling Micro SR602 Small Human Infrared Sensing Module Pyroelectric Probe Induction Switch Sensor PI

Product Introduction

This module has high sensitivity, fast response speed, low static power consumption, compact size, easy to install, lens installed, needle set welded, and no need to debug with power supply. Can be used for human body sensing lights, alarms, security, access control on-demand cameras, agricultural, forestry and mining automatic equipment, etc.

Product Features

1. The high-level output time of this product can be adjusted from 2.5 seconds to 1 hour. The output time set at the factory is 2.5 seconds. If you need to change it, you can modify a surface mount resistor. Please refer to the following description for the resistance values corresponding to typical delay times.

2. Lockdown time, 2 seconds, non adjustable

3. The factory definition is that it can be triggered repeatedly and cannot be changed

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

5. The output timing of the module is: after power on, it outputs a high level for 2 seconds, then changes to a low level and enters standby mode. If the delay time is changed, the time for the module to output a high level after power on will correspondingly increase, which can be understood as the startup time for entering normal working state after power on will increase

6. After installing the photosensitive element, it does not work during the day and works at night. Without installing photosensitive components, this product works all day long and defaults to not having photosensitive components installed

7. This module is very sensitive, pay attention to the installation position, and try to avoid heat sources and radiation sources (air vents/direct sunlight) as much as possible

8. The sensitivity of this module is adjustable, and a patch resistor needs to be changed

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

Product Advantages

1. Exquisite appearance, high performance, high cost-effectiveness, embedded installation.

2. Imported battery cells are used, with a small size to ensure effective protection both inside and outside while maintaining strong usability.
