Model：HFS-DC03-12V
Frequency：5.8G      Band：ISM       

Size：31x22x12mm
Minimum Input Current：30mA     
Output Type：5V  TTL ( High-level Output caused once triggered )
Input voltage：DC12-30V(Input voltage should go through voltage stabilization, no-load Voltage should be ≤30V)
Connection Type：VCC connecting with power positive, GND with power negative, GND and OUT connecting with TTL output.
Installation Height：2-6m(S ested)  
Detective Distance：Right Ahead 12m      
Detective Range: Straight Ahead 360° 
Delay 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 ：5.8GHZ High 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, continuous trigger would be caused. (the load lamp may be continuously triggered by itself or couldn’t be powered off );
2, For its working properly,  avoiding below enviroments: 
a, Being installed in the side of a large area of metal;
b, Being put in a completely closed metal shell;
c, Being put together with other wireless high-frequency products.
