BLE wireless surveillance camera with Android smartphone
If you own Android smartphone with Bluetooth 4.0 and Android version min. 4.4(KitKat), you can easily change it to surveillance or hunting camera.
Just make PIR sensor(HC-SR501), BLE module (JDY-08) and STM8S103 microcontroller based wireless movement detector .
This could be done easily without STM8S microcontroller using another BLE module with embedded IDE to develope software to communicate to Android application.
Bluetooth Low Energy wireless motion sensor
Low power motion sensor consumes about 0,5 mA on active BLE connection sleep mode. But it consumes 9 mA in active connection state, when motion is detected.
Prototype hardware looks like this:
Android applications(2 pcs)
I have developed 2 Android applications one to handle BLE link to motion sensor and another to handle camera features (based to Open Camera app).
BLE link application has the feature of proximity screen off to reduce power consumption to typically 30 mA. It also launches , controls and stops camera application.
Camera application has the main features of Open Camera and allows good quality video and still images.
