Senba D205B Analog PIR Sensor - Wide-Angle Motion Detection
The Senba D205B is an analog PIR (Passive Infrared) sensor module designed for security and automatic lighting applications. It provides a high-sensitivity voltage output signal compatible with 3.3V and 5V microcontroller systems like Arduino, Raspberry Pi, and ESP32 for detecting warm, moving objects.
Features
- High-sensitivity analog output signal (≥5000mV Vp-p) for precise motion detection
- Wide detection angle and spectral response optimized for human body IR (5–14μm)
- Low power consumption with a broad operating voltage range from 3V to 15V DC
- Robust operating temperature range from -30°C to +75°C for indoor/outdoor use
- TO-5 metal-can encapsulation for stable performance and environmental protection

The Senba D205B Analog PIR Sensor operates on the principle of detecting changes in infrared radiation emitted by warm objects in motion. Its pyroelectric sensing element, featuring a 4-element IR receiving electrode, generates a differential analog voltage signal proportional to the rate of change in IR energy, enabling reliable detection of slight movements.
The module’s internal signal conditioning provides a clean, high-amplitude output suitable for direct interfacing with analog-to-digital converters (ADCs) on microcontrollers or dedicated alarm panels. The TO-5 metal package ensures mechanical durability and shields the sensitive detector from environmental interference, supporting consistent operation across a wide temperature range.
