Senba SB412A PIR Motion Sensor Module w/ AM412 Sensor - 2s-80min Delay, 3-12V DC
The Senba SB412A is a passive infrared (PIR) motion sensor module based on the AM412 sensor, featuring a wide configurable delay range from 2 seconds to 80 minutes. Operating from 3-12V DC, it is designed for easy integration into Arduino, Raspberry Pi, and ESP32 projects for security, lighting automation, and energy management systems.
Features
- Wide Adjustable Delay Range: Configurable trigger hold time from 2 seconds up to 80 minutes for versatile application timing.
- AM412 PIR Sensor Core: Utilizes a reliable pyroelectric infrared sensor for stable human/animal motion detection.
- Broad Operating Voltage: Compatible with 3V to 12V DC power supplies, suitable for both 3.3V and 5V logic systems.
- Compact Form Factor: Measures just 18mm x 10mm for integration into space-constrained designs and enclosures.
- No External Light Sensor: Operates independently of ambient light conditions without a CdS photocell.

The Senba SB412A module integrates the AM412 PIR sensor, which detects motion by sensing changes in infrared radiation emitted by warm bodies. The onboard SB412A processing chip conditions the analog signal and provides a digital output pulse, with the duration of this output being user-adjustable across an extensive range. This design eliminates the need for external timing components, simplifying circuit design.
Built around MOSFET technology, the module offers stable performance across its specified operating temperature range of -20°C to +60°C. Its high sensitivity and built-in signal processing are engineered to minimize false triggers from environmental noise, making it suitable for reliable, long-term installations in both indoor and protected outdoor environments where precise motion-activated control is required.
