LM35 Regulator Features:
- Minimum and maximum input voltage is 35V and -2V respectively. Typically 5V.
- Can measure temperature ranging from -55°C to 150°C
- Output voltage is directly proportional (linear) to temperature (i.e.) there will be a rise of 10mV (0.01V) for every 1°C rise in temperature.
- ±0.5°C Accuracy
- Drain current is less than 60µA
- Low-cost temperature sensor
- Small and hence suitable for remote applications
- Available in TO-92, TO-220, TO-CAN, and SOIC package
How to use LM35 Temperature Sensor:
LM35 is a precision integrated circuit temperature sensor, whose output voltage varies based on the temperature around it. It is a small and inexpensive IC which can be used to measure temperature anywhere between -55°C to 150°C. It can easily be interfaced with any microcontroller that has an ADC function or any development platform like Arduino.
Power the IC by applying a regulated voltage like +5V (VS) to the input pin and connect the ground pin to the ground of the circuit. Now, you can measure the temperature in the form of voltage as shown below.
