Another interesting item in the SunFounder 37 modules sensor kit is the relay module. This can be used to control electrical devices that cannot be connected directly to the Raspberry Pi because of higher voltage or current. In this example the relay will activate a floodlight built with 32 infrared LEDs to take a photo in the dark using the Raspberry Pi NoIr camera.
The second module in the SunFounder 37 Modules Sensor kit is a RGB – LED. Using PWM it is possible to combine the 3 colors (red, green and blue) to almost any other color. Again I will use a web frontend to control this LED
The first module in the SunFounder 37 Modules Sensor kit is a dual color LED. I will show how to control it using a simple web interface and a python server. There will be a simple website with 3 buttons: red, green and off which will be used to control the LED connected to the Raspberry PI.
Today I received the SunFounder 37 Modules Sensor Kit V2.0 for Raspberry Pi 2. Compared to the old sensor kit from SunFounder there are several improvements and also some more interesting sensors.
The first improvement is that the manual now includes circuits for every sensor and the manual seems to be much more detailed. Some of the new sensors are a real time clock (RTC), a LCD display, a barometer, an ultrasonic distance sensor and many more. Many other sensors where already included in the first kit.
So again this kit promises many hours of nerdy fun. I am planning to write some blog posts about the kit within the next weeks and months.
