About the speed information in NMEA0183 sentence GPRMC
1. What is the speed unit in GPRMC? I checked online and some said it is knots, some said it is nautical miles, which one is it, I don't have the conditions to test it here 2. What is the speed range
Photoelectronic thermometer circuit diagram
[size=5]This device is used to measure the temperature of an incandescent lamp. When the temperature rises, the black body radiation spectrum shifts to shorter wavelengths. The filter is used to separ
I need help with how much larger the outer diameter of a PCB plug-in hole should be than the inner diameter of the hole. Is there a formula to calculate this?
