LM35D Digital Temperature Sensor Linear Module

Description

The LM35D is a digital temperature sensor linear module that measures the temperature in Celsius degrees. It is designed to provide a linear output voltage that is directly proportional to the temperature in degrees Celsius. The LM35D is a small, low-cost, accurate, and easy-to-use temperature sensor that is widely used in many applications.

The LM35D has a wide temperature range of -55°C to 150°C, with an accuracy of ±0.5°C at room temperature. It operates on a single power supply voltage of 4-30 volts and consumes very low power, making it ideal for battery-powered applications. The output of the LM35D is a linear voltage that varies with temperature, with a sensitivity of 10mV/°C.

The LM35D is a three-lead device, with a ground pin, a power supply pin, and an output pin. The output voltage of the LM35D is directly proportional to the temperature, with a scale factor of 10mV/°C. For example, at 25°C, the output voltage of the LM35D will be 250mV.

The LM35D is easy to use, as it requires no external calibration or signal conditioning circuitry. It can be connected directly to the input of an analog-to-digital converter (ADC) or a microcontroller with an ADC input. The LM35D can also be used with an op-amp to amplify the output voltage if necessary.

The LM35D is widely used in temperature control applications, such as temperature sensing in HVAC systems, temperature monitoring in industrial processes, and temperature sensing in automotive applications. It is also used in medical equipment, food processing, and many other applications where temperature sensing is required.
