Description
Introduction to LM 35 Temperature Sensor
The LM 35 Temperature Sensor is a highly precise device used to measure temperature in degrees Celsius. Unlike thermistors, it requires no external calibration. Consequently, it is ideal for both beginners and professionals working on electronics projects. Moreover, its ease of integration with microcontrollers makes it a go-to sensor for temperature measurement.
Working Principle of LM 35 Temperature
The LM35 works by generating an analog voltage that is directly proportional to the temperature. In other words, it outputs 10mV per °C, simplifying the conversion to Celsius. Because of this, there’s no need for complex calculation formulas. As a result, users can directly interpret sensor data when paired with devices like Arduino, PIC, or Raspberry Pi.
Key Features and Specifications
The sensor operates on a voltage range from 4V to 30V, drawing only about 60 µA, which significantly reduces self-heating. Therefore, it provides accurate readings even over long durations. Additionally, the LM35 can detect temperatures from -55°C to +150°C with an accuracy of ±0.5°C at room temperature. Not only that, but it also comes in various package types, including TO-92 and SOIC-8.
Applications of LM 35 Temperature Sensor
The LM35 is widely used across different industries. For instance, it’s used in HVAC systems, medical devices, weather stations, and home automation. In addition, many automotive and industrial systems rely on this sensor for accurate thermal data. Thus, LM 35 Temperature Sensor is a versatile choice for any temperature-sensitive setup.
Interfacing LM35 with Microcontrollers
The sensor connects easily with microcontrollers through its analog output pin. After wiring, users can read the voltage via the microcontroller’s ADC (Analog-to-Digital Converter). Then, simple code converts the signal into a readable temperature value. Ultimately, this makes the LM35 an efficient tool for real-time monitoring.
