Product Description

MH-SR602 Mini PIR Motion Sensor Detector Module

= Ultra-Compact Pyroelectric Infrared Sensor for Arduino and DIY Projects =

The MHSR602 is an ultracompact, lowpower PIR (Pyroelectric Infrared) motion sensor module designed to detect human body movement within a range of up to 5 meters. Its tiny 15x15mm footprint and 20µA quiescent current make it ideal for batterypowered and space-constrained projects like smart lighting, security alarms, and automatic door systems, working seamlessly with Arduino and other microcontrollers .

UltraLow Power Consumption (20µA) Ideal for batterypowered applications and energysaving devices.
Wide Operating Voltage - Accepts any voltage from 3.3V to 15V DC, compatible with 5V and 3.3V logic .
The module's output is a simple TTL digital signal: HIGH (3.3V) when motion is detected, and LOW (0V) when no movement is present .
No library is required to use this sensor with Arduino, making it very straightforward to implement .
Do not expose the module to direct sunlight, heat sources, or air vents, as this can cause false triggers due to its high sensitivity .

Key Features

+High Sensitivity, Fast Response Reliable motion detection with a compact, easyto-install design.

+Adjustable Delay The highlevel output time can be modified from 2.5 seconds to 1 hour by changing a chip resistor, allowing for long-duration triggers .

+Repeatable Trigger - The timer resets with each new detection, ensuring devices stay active as long as motion is present .

+Photosensitive Option - The module has a footprint for adding a photodiode, allowing it to be configured to operate only at night .

Applications

  1. Body Sensor Lights and smart lighting systems .
  2. Security Alarms and intruder detection systems .
  3. Access Control and on-demand imaging systems .
  4. Batterypowered and portable devices due to its ultralow power consumption .
A top choice for battery-powered projects where space and power are at a premium.
Excellent lowpower alternative to larger PIR sensors like the HCSR501.

OUTDigital Signal Output (3.3V / 0V)
This module is exceptional for battery-powered projects due to its 20µA quiescent current, which is significantly lower than other common PIR sensors .

Troubleshooting

False triggers or inconsistent readings:

  • Avoid direct sunlight, heat sources, and air vents, as the sensor is highly sensitive to temperature changes.
  • Ensure a stable power supply, as voltage ripples can cause false triggers .
  • If the module powers on and outputs HIGH for a short time, this is normal behavior during its startup sequence .
