USB Voltmeter Kit
USB Voltmeter Kit
USB Voltmeter is a PC based dual channel voltmeter built around PIC18F2550 microcontroller that measures voltage from 0.00V up to 500.00V with 10mV resolution. USB Voltmeter sends measured data to PC via standard USB connection displaying data on a computer monitor. USB Voltmeter is self-powered drawing very little current from USB port. Voltage readings are displayed via included USB Voltmeter software.

USB Thermometer Kit with Data Logger
USB Thermometer Kit with Data Logger
USB Thermometer allows to measure temperature in two different locations. Two Microchip MCP9700 temperature sensors in standard TO-92 package are used to sample temperature and allow to measure temperature from -40 to +125 Celsius degrees. Simply connect to a PC computer via standard USB cable and temperature readings will be displayed using included USB Thermometer software. USB Thermometer takes power directly from USB port and does not need external power supply. Temperature readings can be displayed in both Fahrenheit and Celsius degrees.

USB Thermometer software comes with Data Logger feature. Date, time and temperature readings are saved to a text file and can be used to create various graphs via Microsoft Excel or any other statistical software. The software will log temperature every x amount of time which can be set from a second up to a day.

USB IO Board Kit
USB IO Board Kit
USB IO Board is a tiny spectacular input / output development board (parallel port replacement) that can be used for controlling many different devices as well as data acquisition such as collecting data from sensors, buttons, voltage/current measurements, etc. It is based around single PIC18F2550 microcontroller chip that includes    10x 10-bit Analog to Digital Converters (ADC) for precision voltage/current measurements. Controlling USB IO Board is easy. When attached to Windows PC USB IO Board will show up as RS232 COM serial port. You can control 16 individual microcontroller I/O pins by sending simple serial commands or write your own custom C#/VB.NET application. USB IO Board is self-powered by USB port and can provide up to 500mA for your project needs. USB IO Board is breadboard compatible. Simply solder included 12-PIN & 8-PIN male headers on the bottom side of the PCB and the board can be plugged into a breadboard for quick prototyping. USB IO Board is compatible with Windows 10, 8, 7 (32/64-bit), XP, VISTA, Win2K, Mac OSX and Linux.
