Description

The Senba W216S utilizes a dual-element pyroelectric sensor within a TO-5 metal can, sensitive to infrared radiation in the 5-14µm wavelength range. Its core function is to detect changes in thermal energy caused by moving objects and output a corresponding analog signal. The integrated EMI filtering circuitry is critical for operation in electrically noisy environments, preventing false triggers from sources like switching power supplies or motors.

This sensor is engineered for durability across an operating temperature range of -20°C to 70°C. Its analog nature provides flexibility for threshold adjustment in the host controller, allowing sensitivity tuning for specific applications. The compact form factor and standard pinout facilitate straightforward installation into wall sconces, outdoor lights, and automated control panels.

Key Features

  • EMI-Filtered Analog Output: Internal filtering minimizes false triggers from electromagnetic noise, ensuring stable signal integrity.
  • Wide-Angle Pyroelectric Detection: Dual-element sensor with a 110° detection cone provides broad area coverage.
  • Broad Voltage Compatibility: Operates from 4.5V to 20V DC, supporting integration with 5V, 12V, and other common low-voltage systems.
  • Low-Noise Sensor Element: Features high sensitivity (≥3300V/W) and low inherent noise (<70mV) for precise motion sensing.
  • Durable TO-5 Metal Housing: Standard encapsulation protects the sensitive IR elements and ensures consistent performance.
  • Energy-Efficient Operation: Low power draw makes it suitable for battery-backed or always-on applications.

Applications

  • Automatic activation for LED wall lamps, porch lights, and stair lighting.
  • Energy-saving triggers for security lighting and outdoor area illumination.
  • Presence detection in low-traffic areas like closets, pantries, or garages.
  • Motion-activated signage or display lighting in retail environments.
  • Basic intrusion detection as part of a DIY security or home automation system.

Frequently Asked Questions

What is the output signal type of the W216S sensor?

The W216S provides an analog output signal. The voltage level changes in response to detected infrared radiation from motion. This analog signal must be read by a microcontroller's ADC pin or a comparator circuit to trigger an action, such as turning on an LED light.

What is the purpose of the Anti-EMI feature?

The Anti-EMI (Electromagnetic Interference) filtering circuitry minimizes electrical noise picked up by the sensor's wiring and internal components. This prevents false triggers caused by nearby motors, switching power supplies, or other sources of electrical noise, ensuring motion detection is based solely on thermal changes.

How do I wire and power the W216S PIR sensor?

Connect the V+ pin to a DC power source between 4.5V and 20V, and the GND pin to ground. The output signal pin provides the analog voltage. Always refer to the specific pinout diagram for your module. Ensure power polarity is correct to avoid damaging the sensor.

Can this sensor work outdoors?

While it has a wide operating temperature range (-20°C to 70°C), the standard TO-5 package is not inherently waterproof. For outdoor use, the sensor must be installed inside a sealed, weatherproof enclosure with an IR-transparent window to protect it from moisture, dust, and direct sunlight.
