Con-tactless Thermometer – Pyrometer

The device was designed for con-tactless monitoring of temperature. It is also capable to record the temperature measurements and upload them to a computer via the serial interface. The device is based on TI’s MSP430RF5728 microcontroller with FRAM type of memory instead of conventional Flash. It needs just 3 external caps to operate (C11 – C13) and uses SPI interface to communicate with μC at 8 MHz frequency. The device operates in 3 main modes which are selected with a slider switch. The measurements can be stopped and started by the “mode” button which is convenient for monitoring some difficult to access devices. The monitoring period is set with “<” and “>” buttons and is displayed in the bottom right corner of the screen. Turning the device into the temp… Continue reading
