NTC Thermistor Temperature Sensor Module

Description:

• It utilizes an NTC thermistor, a resistor whose resistance decreases as temperature increases.
• The module typically includes the thermistor, a comparator (like the LM393), and a potentiometer for adjusting the temperature threshold.
• It provides both digital (on/off) and sometimes analog output, allowing it to be easily integrated with microcontrollers and other electronic systems.

Key Features:

• High Sensitivity: NTC thermistors are very sensitive to temperature changes.
• Adjustable Threshold: The potentiometer allows users to set the temperature at which the digital output switches.
• Digital and Analog Output: Provides flexibility in how the temperature data is used.
• Compact Design: Typically small and easy to mount.
• Wide Operating Voltage: Usually compatible with 3.3V to 5V power supplies.
• LM393 Comparator: Provides a clean and stable output signal.

Applications:

• Temperature Monitoring: Used in various applications to monitor and control temperature.
• Environmental Monitoring: Measuring ambient temperature in weather stations, HVAC systems, etc.
• Industrial Process Control: Monitoring and controlling temperatures in manufacturing processes.
• Medical Devices: Patient monitoring, temperature regulation in incubators, etc.
• Home Automation: Controlling heating and cooling systems.
• 3D Printers: Monitoring hot end and heated bed temperatures.
• Water tank temperature control.

Specifications:

• Operating Voltage: 3.3V - 5V DC.
• Temperature Sensing Range: Typically -25°C to +80°C (but this can vary).
• Output Type: Digital (0 and 1) and often Analog.
• Comparator: LM393.
• Current Drive Capacity: >15mA (typical).

DATA SHEET AND USECASE

Datasheet Overview:

The module typically includes an NTC thermistor and provides both digital and analog outputs. Key features often include:

• Temperature Measurement Range: Approximately -55°C to +125°C.
• Outputs:
  • Digital Output (DO): Indicates whether the temperature exceeds a set threshold, adjustable via an onboard potentiometer.
  • Analog Output (AO): Provides a continuous voltage corresponding to the measured temperature.
• Power Supply: Typically operates at 3.3V or 5V, making it compatible with most microcontrollers.
