Description:
The LM35 is a high precision temperature sensor. It has a analog output, which is linearly proportional to the surrounding temperature. Just hook it up to a ADC pin on your microcontroller to get temperature readings.
Features of Temperature Sensor are as follows:
- Calibrated Directly in Celsius (Centigrade)
- Linear + 10-mV/°C Scale Factor
- 5°C Ensured Accuracy (at 25°C)
- Rated for Full −55°C to 150°C Range
- Suitable for Remote Applications
- Low-Cost Due to Wafer-Level Trimming
- Operates from 4 V to 30 V
- Less than 60-μA Current Drain
- Low Self-Heating, 0.08°C in Still Air
- Non-Linearity Only ±¼°C Typical
- Low-Impedance Output, 0.1 Ω for 1-mA Load
This LM35 sensor can be used to develop many Internet of Things applications.
following are some of IoT application with using LM35
- IoT Temperature data logger using ESP8266 and LM35
- Surrounding temperature measurement using Arduino
