Input voltage::Dc12-30v(input voltage need to go through voltage stabilization, no-load voltage should be ≤30v)

Detective time:For the testing convenience, sensing delay time is set to be the quick test mode (delay 2s) before the product leaving the factory;
For 25s time delay, disconnect the solder tin as above pic a point, the time will be extended;

Working method:
High-level output caused for the first time powered on, after 2s becoming low level, then with self-test time 6s(don't receive any external signals) , entering into the normal working operation afterwards .

Features :5.8g frequency, it does not interfere with each other with normal installation and usage, high stability, strong anti-interference ability, small volume, suitable for all kinds of dc microwave module products.

Notes:
1, it is noted that the input current should be ≥30ma to drive the module.And the voltage should be stable without big fluctuation.Otherwise, it will cause continuous trigger (the load lamp may be continuously triggered by itself or couldn't be powered off )
2, for its working properly,  avoiding being installed in the side of a large area of metal , avoiding being put in a completely closed metal shell, avoiding being put together with high-frequency wireless products
