CircuitGizmos provides products for sale that are designed and produced by the creative minds at CircuitGizmos, USBmicro, Amber Waves Electronics, and other fun sources of clever engineering.
Here you can purchase the USBmicro U401 and U421 USB interface that has support for SPI, LCD, 1-wire, stepper motor control, input, and output.
CircuitGizmos sells the Color Maximite 2 Computer in the form of the CG RetroMax. The Maximite runs BASIC and supports a display on VGA. A keyboard can interface to the Maximite as well as I2C, SPI, and serial devices.
The Sensor.Engine:Micro is a great way to augment a solderless breadboard and interface to things like the small boards in the 37 sensor kits. This is an easily programmed STEM controller.
CircuitGizmos also sells the unique USBPIR USB motion detection module and home automation and security software made to work with these devices.
1-wire temperature monitoring
The Maxim/Dallas DS1822 is a "1-wire" digital thermometer. Data is read out over the 1-Wire (single wire data/power connection, plus ground) bus. The device has an accuracy of ±2°C over a -10°C to +85°C range. Full range of -55°C to +125°C (-67°F to +257°F)
Multiple DS1822 devices can be attached on the bus and addressed by the device's unique 64-bit serial number. Used with the U401 or U421 the DS1822 can provide remote temperature monitoring/measurement.
