raspberry pi camera python motion detection

The DHT11 is a temperature and humidity sensor with calibrated digital signal output. Precision humidity +-5%RH, temperature +-2℃, range humidity 20-90%rh, temperature 0~50℃. I bought a good package of modules, the top with a pull-up resistor, directly to the Raspberry Pi can be gray, purple, blue respectively represents data, 3.3V, 0V, to the Raspberry

On-line tutorials, general Python with Rpi.gpio to control the Raspberry Pi Gpio, and C + + generally use WRINGPI library to operate Gpio,rpi.gpio too simple, many advanced features do not support, such as I2C/SPI library, etc., but also lack of high-precision timing and other advanced features. In contrast, WIRINGPI is rich in functionality, but in fact WRINGPI

Introduced The DHT11 is a cheap accessory that includes temperature and humidity sensors, and the code is easy to use. This article describes if you use DHT11 in a Raspberry Pi, the code is python. If you have any questions, please leave a comment below. Wiring VCC Connection 5V or 3.3V Data is connected to the Gpio (I'm picking up the B
