Temperature sensors are essential components of any electronic design which require temperature monitoring and regulation. The LM35CZ temperature sensor is a widely used temperature sensing device and falls in the category of analog and digital output temperature sensor. This article discusses in detail the application field and working principle of LM35CZ temperature sensor.

Overview

The LM35CZ is an Analog Output Temperature Sensor which can provide temperature range from -55°C to 150°C with an accuracy of ±0.5°C. It has three pins; one is for power supply, second one is for ground and third one is for temperature output. It has a linear voltage output and operates at a supply voltage range of +4V to +20V DC.

Application Field

The LM35CZ temperature sensor is used in a wide variety of applications where precise temperature control and monitoring are required. It can be used in HVAC systems, in semiconductor processing equipment, medical imaging systems, automotive thermostats, and in a host of other applications. It is suitable for surface temperature sensing and temperature compensation. It is also widely used in environmental monitoring and process control applications.

Working Principle

The working principle of the LM35CZ is based on the Thermoelectric Effect. The device consists of an integrated circuit that is sensitive to temperature changes and produces an electrical voltage output in accordance to the amount of temperature change sensed. The output is a linear voltage signal that corresponds to the temperature detected by the device. The thermoelectric effect is the process by which two dissimilar conductors in contact with each other will produce a voltage when subjected to a temperature change. The thermoelectric effect in a temperature sensor works on the principle of the Seebeck effect. When a temperature difference is created between two dissimilar conductors, a voltage difference is generated. This voltage difference is proportional to the temperature difference and can then be used to accurately measure the magnitude of temperature.

Conclusion

The LM35CZ temperature sensor is an Analog Output sensor which can provide temperature range from -55°C to 150°C with an accuracy of ±0.5°C. It is widely used in industrial and domestic applications due to its accurate temperature sensing capabilities and linear voltage output. The working principle of the LM35CZ is based on the Thermoelectric Effect which creates a voltage difference proportional to the temperature difference.
