The theory:
The device can automatic play the sounds of fowls and beasts to drive away birds and animal (such as birds,boars,cats,dogs,etc.) via function adjust switch according to different environmental needs.
Applicability:
Passive infrared bird repeller: suitable environment garden,yard,farms,orchard and so on.
Technical data:
1.Power Supply: 4*D (R20) batteries
2.Passive infrared area: about 70 square meters
3.Passive infrared degree: 110 degree
4.Output sound pressure : 110 dB
5.Output power: 2.5W
Specifications :
The passive infrared bird repeller has two working settings.
One pattern is automatic; the other pattern is triggered by the passive infrared detector.
Mode one (Adjust the switch to the ‘auto’. (Refer to the diagram)
This will play the sounds for 30 seconds every 30 minutes. The device can automatically identify night and day so that it does not work in the night time.
The passive infrared does not work in this mode.
Mode two (Adjust the switch to the ‘PIR’ (Refer to the diagram)
The passive infrared trigger will work when the animal enters into the passive infrared area. The device will play the sounds continuously for 30 seconds and after 5 seconds it will detect again.
