Temperature sensors are vital components in any electronic system, for accurate detection and measurement of temperature. Temperature sensors detect differences in temperature in the environment or in contact with objects, and can be used for a variety of applications such as heating, cooling, environmental control, and others. The two main types of temperature sensors are analog and digital output. The LM335MX is one of the most widely used temperature sensors that use an analog output.

Function and Structure of LM335MX

The LM335MX is a precision temperature sensor manufactured by Texas Instruments. It is based on a transistor-controlled resistor voltage divider structure, and provides a linearized output voltage that is proportional to the temperature. The LM335MX is available in a variety of packages, including a 2-pin ceramic, a 3-pin metal, and a 5-pin metal. It is rated for operating temperatures of -30°C to 150°C. The output voltage is typically 10mV/°C, and can be adjusted using an external resistor.

LM335MX Application Field

The LM335MX is a widely used temperature sensor in a variety of applications, including thermometers, humidity control, temperature controllers, automotive applications, and others. It is especially suitable for applications where low temperature accuracy is necessary. It is also used in air conditioning systems, medical equipment, and other temperature sensitive devices. The LM335MX can also be used in projects such as temperature sensing for residential and commercial buildings, irrigation systems, and climate control systems.

LM335MX Working Principle

The LM335MX temperature sensor works by using a transistor-controlled resistor voltage divider structure. When the temperature changes, the resistance of the transistors in the circuitry changes, which in turn changes the output voltage of the sensor. The output voltage is proportional and linearly scaled to the temperature, typically 10mV/°C. The output voltage can be calibrated by using an external resistor. The LM335MX has a low offset error, and is capable of detecting temperatures of up to 150°C with an accuracy of ±0.5°C.
