Feature: 1. This PIR sensor uses a digital fuzzy logic infrared control system and intelligent analysis algorithm, which can distinguish between interference signals and human motion signals to avoid fault alarms. 2. Can achieve fully automatic temperature compensation. Uses temperature compensation and airflow technology to adapt to environmental changes. 3. Has low voltage alarm function. It automatically reflects low voltage to help GSM alarm send low voltage messages to the user. 4. Uses CMOS low-power microprocessor and the transmission of digital wireless signals, with the function of anti-white light and high frequency interference resistance. 5. Low power consumption and longer battery life. Comes with CR2032 battery, and can be charged in DC5V. 6. This detector is environmentally friendly, safe and easy to install. 7. Suitable for residential, villa, factory, warehouse, office building, etc. Specification: Item Type: PIR motion detector Condition: Brand new Material: ABS plastic Color: White Working Voltage: DC5V Mode of Power Supply: 1 x CR2032 battery(built-in) Quiescent Current: ≤20uA Emission Current: ≤25mA Launch Distance: ≥150m/492.13ft Launch Mode: 433 Detection Distance: Approx.4-8m/13.1-26.2ft Detection Angle: 45 degree Ambient Temperature: -10 ° C - 50 ° C.
