The Senba D204B PIR motion sensor utilizes an active detection principle with a dual-element pyroelectric ceramic detector. The dual-element design provides common-mode rejection, effectively suppressing false triggers caused by ambient temperature fluctuations and electromagnetic interference (EMI). The integrated FET source follower buffers the signal for direct interface with control circuits.
Engineered for stability across an operating temperature range of -20°C to 70°C, this sensor delivers reliable performance in indoor environments. Its compact form factor and simple three-pin interface (VCC, GND, OUT) facilitate easy integration into lighting controls, security alarms, and automated toy or display systems.
