Paradox NV780 Digital Outdoor Dual Side-View Detector Paradox NV780 Digital Outdoor Dual Side-View Detector (wired) and NVR780 (wireless) were designed to provide a pre-entry protection solution while keeping the perimeter free for movement without generating false alarms. The NV780/ NVR780 provides early warning detection, before intruder entry, with excellent exterior/interior wall and window protection.Available in both wired (relay and/or Paradox EVO BUS) and wireless versions (433 MHz or 868 MHz), these rugged indoor/outdoor detectors incorporate two passive infrared side-by-side detectors, each containing two independent dual element sensors, optics, and electronic channels.The optics are specially designed to provide multiple narrow beams (two pairs per side, eight total) for excellent detection and false alarm rejection, covering up to 12m (39ft) for each side. The NV780/ NVR780 are configurable to report as a single unit (2 sides of the unit report to a single zone output) or dual units (each side reports to a separate zone). The NVR780 provides extended battery life operation with Paradox Effi+ circuit. Developed for outdoor conditions with bright LED indication on each side, and buzzer for detection verification. The optics offer simple and easy independent low beam adjustment for coverage flexibility. Advanced Digital Technology Two double passive infrared motion detector with eight narrow detection beams, managed by Full Authority Digital Electronics Control (FADEC) High-resolution and full dynamic range digital signal conversion High-speed, advanced algorithm digital signal processing Digital EMI / RFI interference rejection True Pet Immunity, up to 40kg (90lb) Advanced Optical Technology 4x dual element sensors arrangement High efficiency long focal point (1.77”) lens, providing longrange narrow beams 2 pairs of narrow beams per side provide 2x signals per protected area crossing for increased“catch” and false alarm rejection Combination optics of mirror reflector and 2nd generation Fresnel“LoDiff” Lens Increased white light rejection Easy Installation and Setup Single or Dual Zone operation modes: two sides can report to a single zone or to two separate zones Optical and digital range adjustments Bright LED and buzzer indicator for clear adjustment feedback No need for PCB removal Wall mount, with built-in level tool In-field firmware upgradable via serial port Immediate Perimeter Protection Paradox NV780 Digital Outdoor Dual Side-View Detectors distinct beam pattern creates a narrow, 24m (78.8 ft.) long detection zone (12m / 39.4 ft. each side), to protect wide horizontal areas such as a house’s perimeter. To avoid detection of unwanted objects, it will only trigger an alarm if both beams are crossed. Adjustable Detection Range Paradox NV780 Digital Outdoor Dual Side-View Detector will only trigger an alarm if both beams are crossed. The detection range can be adjusted (both vertically and horizontally), to avoid detection of unwanted objects. Each side’s lower beam can be independantly adjustled within two positions (see fig.1). In addition, both beams’ distance from the wall can be adjusted (horizontally) from 0° to 3° degrees (see fig.2).

Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil. 2. Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low. 3. The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture. 4. The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment. 5. Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture. Package Included: 3 x Soil moisture detector module 3 x Probe 3 x 2P Jumper Cable
