The Pololu USB to serial adapter is great for connecting microcontroller designs to a personal computer. The adapter uses 3.3 V signal levels so you can connect it directly to any microcontroller running at up to 5 V without the hassle of an RS-232 to TTL level converter.

O sensor de fluxo de água consiste em um corpo de válvula de plástico, um rotor de água e um sensor de efeito hall. Quando a água flui através do rotor, o rotor rola.

This compact carrier board makes it easy to integrate a Sharp GP2Y0A60SZLF analog distance sensor (not included) into your project by providing all of the required external components and a 0.1?-pitch, four-pin interface to the sensor. This version of the carrier board is configured for 3V mode.
