Microwave Presence Sensor RF Module NP BW 1.0

Microwave presence sensor module NP BW 1.0 is an electronic RF sensor module designed for presence or absence detection in the specified area, as well as for sensing human respiratory and motor activity. The module detects objects from up to 13 feet (4 meters) distance. Microwave presence sensor module NP BW 1.0 is designed for integration into security systems where it is necessary to detect presence or absence life sign indicators in a room. The module is a low-power microwave sensor operating in the license-free frequency band ISM 5.8 GHz

Driving Factors for Buying the Sensor Module

• Saving cost on the casing of the assembled NP BW 01.00 device
• The will to substitute NP-A22-5800 antenna installed in the assembled NP BW 01.00 device
• The will to substitute NP MB BW interface module installed in the assembled NP BW 01.00 device

Advantages of the Microwave Presence Sensor Module

• Relatively small size
• Unlicensed frequency band
• Relatively long range
• Adjustable sensitivity zone
• Adjustable angle of the sensitivity area via optimal antenna selection
• A powerful ARM processor for digitizing and processing data
• Normally opened relay contacts for loaing
• USB interface for computer communication

Installation and Applications

Microwave presence sensor module NP BW 1.0 can be used as a part of security systems, personnel call systems, nurse call systems, surveillance systems and in other systems as a presence detector, a breathing sensor or a motion sensor. The device should be placed in a well ventilated housing. If the antenna is placed inside the housing, the housing must be non-metallic. Position of the module in the housing can be arbitrary.
