It provides the temperature measurements in Degree Celsius with a resolution of 9-bit to 12-bit. Otherwise, the functionality is basically the same. com along with any suggestions or comments you may have. Presentation Video:Before we start let's see more information about this sensor. 5v linear power supply. IIC, I2C, TWI Interface to Parallel Digital Outputs. The IC has just 3 pins, 2 for the power supply and one for the analog output. To charge a 12 V battery, however, it should be at least 13. 59 Ultrasonic Thickness Meter Tester Gauge Measure 1.
