Key features
- Imported FC412 probe integrates the digital smart control circuit and sensing element inside an EMI-shielded can.
- Very-high-impedance differential input feeds the smart IC, which converts to 15-bit digital and raises the REL output when the PIR signal crosses the threshold.
- Delay time set by resistor; all signal processing on one chip.
- Note: allow 30 s warm-up after power-on; default output is low (LED on), going high on detected motion (LED off); new revision removes the potentiometer with unchanged functionality.
Frequently asked about this product
How do I connect the Digital Smart PIR Motion Sensor (FC412) to my controller board?
The Digital Smart PIR Motion Sensor (FC412) uses the standard 3-pin GVS (Ground-VCC-Signal) interface with an XH2.54 connector, so it plugs straight into Arduino UNO, ESP32, micro:bit and our sensor shields with a regular sensor cable — no soldering required. It works with Arduino IDE, Mixly, Mind+, Scratch and mBlock.
What voltage does the Digital Smart PIR Motion Sensor (FC412) run on?
The Digital Smart PIR Motion Sensor (FC412) runs from a standard 3.3-5 V DC supply (USB or the controller’s 5 V rail). It draws only a few milliamps in normal operation, so it is safe to power from the controller board itself for classroom builds.
What projects is the Digital Smart PIR Motion Sensor (FC412) good for?
The Digital Smart PIR Motion Sensor (FC412) is built for STEM and robotics education: classroom demonstrations, science-fair projects, robotics club builds and competition robots. It pairs with the rest of our module range — same connectors, same voltage, same toolchain — so students move from first circuit to competition robot without changing platforms.
What certification do the robotics and electronics products carry?
Controller boards, sensors and modules ship with CE marking and RoHS-compliant components, and the range is designed for classroom use under teacher supervision. Product-specific test reports and declarations of conformity are available for distributors on request.
What is the minimum order quantity, and can I get a sample first?
These are standard catalogue lines with stable production, so minimums are low and lead times are short. Samples ship within about a week and are normally credited against a first order. Mixed-SKU cartons are accepted for evaluation orders.
