Simple Circuit Breaker
Even though there are fuses in the car, resetting a circuit breaker is a lot easier than buying and replacing a “one-time-use” fuse. This circuit is simple, uses a handful of readily available parts, is completely electronic, and has a very fast cut off time. A picture of the completed circuit breaker and remotely located FET/Rsense is shown in Figures 1, 2, and 3. Also shown is the completed project PC board. This application is used in a high-amp, low voltage DC supply.
Monitor Indoor/Outdoor Temperature And Relative Humidity With One Device
Using a 16F870 PIC, a two-Line LCD display, and two Sensirion SHT15 temperature/humidity sensors, you can build this handy, portable, battery-powered device which will give you easy, accurate simultaneous temperature and relative humidity readings inside your house and outside your window.
