Temperature Sensor Circuit Diagram Pdf. Circuit diagram help from this book. Lmt70 lmt70a 0 05 c precision analog temperature sensor rtd and precision ntc thermistor ic 1 features 3 description the lmt70 is an ultra small high precision low 1 accuracy.
Lmt70 lmt70a 0 05 c precision analog temperature sensor rtd and precision ntc thermistor ic 1 features 3 description the lmt70 is an ultra small high precision low 1 accuracy. Please note that there is no hysteresis in this circuit so that if the temperature changes rapidly then the relay may switch rapidly. How to use lm35 temperature sensor.
Unlike thermistor linearity of a precision ic sensors are very good of 0 5 c accuracy and has wide temperature range.
It is a small and cheap ic which can be used to measure temperature anywhere between 55 c to 150 c. Lm35 temperature sensor equivalent.
