一、Structure Evaluation
(1) cylinder PU pipe design，large capacity capacitor
(2) providing external power
Suggestion: if the external power is used, please leave it for a long
time to release the electricity
二、Waterproof Evaluation
When the cover of the host computer are closed, pure water to the
host computer for 10 minutes, then open the cover of the host computer,
no leakage.
Suggestion: it cannot be put inversely.
三、Sounds Evaluation
(1) Sound volume cannot be adjusted, but the sound should be less
than 90 decibel. It will have some bad effect on hearing ability
if you are near to it. The capacitor will discharge every two minutes.
It will not disturb farmers’ life.
(2) the coverage is about 2 mu.
四、Effect Evaluation
(1) It is effective for some common birds, for example, pie, sparrow
etc.
(2)It is also effective for some uncommon birds.
五、Service Life Evaluation
(1) The shell is made up of PU pipe. Slow oxidation; the service
life is more than 10 years
(2) Large capacity capacitor is used to discharge every two minutes.
The service life is more than 6 months.
