Motion-Activated DC Switch Module | PIR001T 12–24 V DC Passive Infrared (PIR) Sensor | DIY Hobbyist Projects

The PIR001T is a no-fuss, inline DC motion sensor module designed for hobbyist projects. It features just two input terminals (–IN, +IN) for power and two output terminals (–OUT, +OUT) that switch your DC load directly when motion is detected. With its wide 12–24 V DC operating range, ultra-low standby draw, and straightforward wire-in/wire-out hookup, it’s perfect for anyone who needs a simple, reliable motion-activated switch. Possible Use-Case Scenarios – Automatically turn on 12 V LED strips or work lights when you enter a workshop or shed – Trigger a 12 V relay coil to sound an alarm or flash strobe upon unexpected motion – Switch on a small DC fan or pump only when someone is present, conserving power – Integrate into robotics as a simple “wake-on-approach” sensor for Arduino or Raspberry Pi – Build hands-free door-opening mechanisms or touchless dispensers for hobby enclosures – Set up wildlife or pet monitoring rigs that start recording or logging when an animal passes by

• – Four solder-terminal connections: –IN, +IN (power), –OUT, +OUT (switched output) – Wide operating voltage: 12 V–24 V DC, compatible with automotive batteries, solar systems, bench power supplies – Passive infrared detection up to 6 m (≈20 ft) within a 120° field of view – Clean DC output: connects directly to LEDs, relays, small DC motors, fans, pumps, alarms, etc. – Very low quiescent current (<50 µA) when idle—ideal for battery-powered builds – Compact, rugged PCB with mounting holes for permanent installs
