Thermistors in Single Supply Temperature Sensing Circuits

“RTD Temperature Sensing Circuits” for details.) FIGURE 3: In precision temperature measurement environments, the thermistor is used in a “zero power” condition. In this condition, the power consumption of the thermistor has a negligible affect on the elements resistance. This is a graph of an NTC 10kΩ thermistor resistance-versus-temperature.

Using a Temp Sensor | TMP36 Temperature Sensor | Adafruit ...

· Connecting to a Temperature Sensor. These sensors have little chips in them and while they're not that delicate, they do need to be handled properly. Be careful of static electricity when handling them and make sure the power supply is connected up correctly and is between and DC - so don't try to use a 9V battery! They come in a "TO-92" package which means the chip is …
