Motion Detection in mobilewebcam app
if motion is detected , camera takes 3 pictures; intervall is "refresh time";
motion detection is active again, when 3 pictures are made (after 3x refresh intervall);
set OP Mode: normal;
is working in OP Mode semi background as well, but takes every 2...3 minutes a picture, when screen lock is activated/deactivated;
is not working in background mode;
power consumption is very high compared with background mode;

Re: Motion Detection with PIR Sensor
Panasonic PaPIRS Motion Sensors are ideal for motion triggering;
Type EKMC needs power supply between 3V and 6V, current consumption is 170µA; price about 15€
Type EKMB needs power supply between 2,3V and. 4.0V, current consumption is 6µA; price about 30€
i selected EKMC, because some smartphones need equal or more than 4.0V to detect a external power supply. EKMC may be supplied with 5V.
schedule of Prototype:
Samsung GT-S5830: needs 4.0 Volt trigger voltage
Samsung GT-S5360: needs 3.5 Volt trigger voltage
Google Nexus S: needs 3.5 Volt trigger voltage
Sony Xperia Ray: needs 3.9 Volt trigger voltage
LG Optimus L3: needs 3.9 Volt trigger voltage
ST2: Cut an old USB cable, and connect USB Cable at ST2;
ST3: Connect either 5V (best choice) or Li-Ion Battery;
ST1: connect a LED at ST1 if you want to control the function of the motion sensor;
ST4: Test pin; connect LED flash light for example...

Re: Motion Detection
On Ebay can order PIR modules cheaply.
Some modules need 5V but have long range like 5 m...10m.
Other modules run from 4 V (LiPo cell) but have ca 2 m range.
So a compromise should be met

Re: Motion Detection
Hello,
i know, the Panasonic PIR Sensors are not the cheapest.
I tried out Sensors from Hygrosens. But they are not as fail-safe as Panasonic. And they need 6mA and more...
Panasonic even offers with 6µA current consumtion.
Best regards

Hi
This "PIR triger" work as "charger connected to USB" .... or...?

Re: Motion Detection
Hello Joze
this device is a "USB cable" and is permanently charging your telefone and works as motion detector:
http://www.me-systeme.de/catalog/pir-se ... p-851.html
More informations here: hardware-f17/usb-pir-cable-motion-sensor-t176.html#p455
with this device you need to modify your phone: remove the battery and connect the device and a battery with high capacity:
