Key Features
- 6mm 0.4mm 0.6mm PaPIRs
- 6mm 0.4mm 0.6mm "Plug and Play" Radiation noise No false alarms VDD OUT GND Two times better sensitivity The sensitivity has been significantly improved thanks to a unique slit design of the pyroelectric elements. The separated sensing areas prevent thermal crosstalk between the single sensing elements. Therefore, reliable detection is possible even if the temperature difference between the background (e.g. floor / wall) and the target object (human) is small. (e.g. ∆T = 4°C) Element without slit design Element with slit design Lens Reduced focal length (Distance from element to lens) Detection zones Four times better signal-to-noise ratio Improved signal-to-noise ratio thanks to a special I/V circuit which is used for converting a current signal from the pyroelectric element to voltage. Panasonic PIR motion sensors perform by the feedback capacitor and the operational amplifier, different from the conventional FET-type, thereby decreasing the probability of false alarms due to temperature fluctuation.
