Description
The sensor operates within a temperature range of 32°F to 212°F (0°C to 100°C), making it suitable for general-purpose applications within this range. It has a low output impedance, linear output, and precise inherent calibration, enabling direct interfacing with readout or control circuitry without additional components. The LM34DZ is powered by a low voltage supply, typically between 4V and 30V, and draws minimal current, which makes it suitable for battery-operated devices.
Given its ease of use, accuracy, and low cost, the LM34DZ is widely used in various applications, including HVAC systems, environmental monitoring, and consumer electronics.
Equivalent
1. LM35 series (though in Celsius)
2. TMP36, TMP35 (analog temperature sensors from Analog Devices)
3. MCP9700, MCP9701 (analog temperature sensors from Microchip Technology)
These sensors provide similar functionality with minor variations in scale or output format. Always verify compatibility in your specific application before substituting components.
Features
1. Linear Output: It provides a linear voltage output directly proportional to the Fahrenheit temperature scale. The output is 10 mV per degree Fahrenheit.
2. Temperature Range: It is designed to measure temperatures in the range of 32°F to 212°F (0°C to 100°C).
3. Calibrated Output: The sensor is factory-calibrated in Fahrenheit, so no external calibration is necessary.
4. Low Power Consumption: It operates with a supply current of less than 60 µA, making it energy-efficient.
5. Wide Supply Voltage Range: The sensor can operate over a supply voltage range from 4V to 30V, which offers flexibility in different applications.
6. Low Self-Heating: The device introduces minimal self-heating, approximately less than 0.1°F in still air.
7. Ease of Use: It can be directly connected to a wide range of microcontrollers and other applications without needing additional components or conditioning.
This sensor is suitable for applications in environmental monitoring, HVAC systems, and any system requiring accurate temperature measurements in Fahrenheit.
Pinout
1. Pin 1 (Vout): This is the output pin. It provides an analog voltage that is directly proportional to the temperature in Fahrenheit. Specifically, the output is 10 mV per °F.
2. Pin 2 (Ground): This pin is connected to the ground of the circuit. It serves as the reference point for the output voltage.
3. Pin 3 (Vs): This is the supply voltage pin. The LM34DZ operates with a supply voltage in the range of 4V to 30V.
In summary, the LM34DZ is a simple and efficient device for temperature sensing, providing a direct voltage representation of the temperature in Fahrenheit through its 3-pin configuration.
