概述

Description

The LM35CZ is a precision temperature sensor that provides a linear voltage output proportional to the Centigrade temperature. It's part of the LM35 series, which are known for their accuracy and ease of use. The sensor operates without needing calibration and provides a typical accuracy of ±0.5°C at room temperature. It outputs a voltage of 10mV for every 1°C rise in temperature, making it straightforward to interface with microcontrollers or analog-to-digital converters.
The LM35CZ operates over a wide range of temperatures, typically from -55°C to 150°C, and requires a supply voltage between 4V and 30V. Its low self-heating capability (less than 0.1°C in still air) prevents significant sensor-induced temperature errors. The device is housed in a small TO-92 package, making it suitable for various applications where space is a concern.
Common uses include environmental monitoring, consumer electronics, and industrial temperature control systems. Its ease of integration and reliable performance make the LM35CZ a popular choice for temperature sensing applications.

Equivalent

The LM35CZ is a temperature sensor, and its equivalent products include the LM35 series from other manufacturers, such as the LM35DZ. Other similar temperature sensors include the TMP36 from Analog Devices, MCP9700A from Microchip Technology, and the DS18B20 from Maxim Integrated. All these sensors offer similar functionality for measuring temperature and may vary in specifications like accuracy, temperature range, and output type. Always check the datasheets for compatibility with your specific application.

Pinout

The LM35CZ is a precision temperature sensor with a linear output and is part of the LM35 series. It typically comes in a TO-92 package, which has 3 pins. The pin functions are as follows:
1. Pin 1 (V+ or Vs): This is the power supply pin. The LM35CZ operates with a supply voltage ranging from 4V to 30V.
2. Pin 2 (Vout): This is the output pin. The LM35CZ provides an analog voltage output that is linearly proportional to the Celsius temperature. The output voltage changes by 10mV per degree Celsius, making it easy to convert the voltage reading directly into temperature.
3. Pin 3 (GND): This is the ground pin. It should be connected to the ground of the system to complete the circuit.
The LM35CZ is designed for a temperature range of 0°C to +100°C with a typical accuracy of ±0.6°C at 25°C. Its low output impedance and linear output make it easy to interface with various types of analog and digital systems.
