We can use the sensors with MAX9812 for applications that require measuring the intensity or frequency of the sound.

It consists of three principles of induction of primary colors, if you know the composition of all types of color values, you can know the color of the test object.
For TCS230, a color filter is chosen, only a certain primary pass is allowed, it is stopped by another color. For example, when choosing a red filter, the incident light can only be stopped in red, blue and green, so you can get the intensity of the red beam of light.
For the same reason, the choice of other filters, can obtain the intensity of blue light and green light.
Through these three values, the color of the light can be projected onto a TCS230 sensor. Color Recognition Sensor GY-31 TCS230 TCS3200 features:
- Operating voltage: 3 - 5 VDC
- Model GY-91

12VDC plastic solenoid valve. Normally closed. Liquid can flow in one direction and a minimum pressure of 0.02Mpa (3 PSI) is required. This liquid valve would be a great addition to your robotic gardening project. There are two 1/2 ″ outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve can be opened and pushed.

Mini electricity generator, built base on a turbine and an electric generator that converts kinetic energy into electricity. The generator output is rectified and regulated for a maximum of 12V. Please note -if we want to generate more current, the turbine will oppose the greater resistance to the flow of water, and the voltage may drop if the water flow is not sufficient. This generator is made of plastic and the turbine is totally isolated from the generator and rectifier, the outputs are 1/2 "usually found in domestic pipes.
