Since you have a 10Bit ADC and I quess it measures from 0V to 5V, you can also write:The most exact temperature measurement can be made by using platinum sensors. To connect a 4-wire PT100 sensor. (see the wiring diagrams below) and using only those wires needed for your connection. Let's say we want to measure something which would have a temperature range of -51. 5. It is also possible to. Temperature range-200 to 650°C -200 to1750°C -100 to 300°C Thermal response Wirewound – slow Film – faster. TMP117 High-Accuracy, Low-Power, Digital Temperature Sensor With SMBus™- and I2C-Compatible Interface datasheet (Rev. 706) / 0. The device provides a 16-bit temperature result with a resolution of 0. The PT100 RTD sensor is one of the most accurate temperature measuring instruments with a resistance factor of 100 Ω at 0° C or 32° F with very little drift over time. The circuit uses only one bridge and one differential. 00385 O/O/°C between 0 and 100°C. 47 Ohm), then I get 2.
