TMP36 Low-Voltage Temperature Sensor (TO-92) delivers accurate, low-power analog temperature sensing for embedded and hobbyist projects. Designers read its linear voltage output directly to measure ambient temperature without external calibration.

Key Features:
  • Low-Voltage Operation: Operates from 2.7 V to 5.5 V for battery and microcontroller systems.
  • Linear Voltage Output: Produces 10 mV/°C scale for simple ADC conversion and calculation.
  • No External Calibration: Factory-calibrated output yields reliable temperature readings out of the box.
  • Low Quiescent Current: Draws typically ~50 µA to minimize battery drain.
  • Wide Temperature Range: Measures across a broad ambient range suitable for many applications.
  • TO-92 Through-Hole Package: Fits breadboards and through-hole PCBs for prototyping and production.
Technical Specifications:
  • Supply Voltage: 2.7 V to 5.5 V
  • Output Scale: 10 mV per °C (VOUT = 500 mV at 0 °C; 750 mV at 25 °C)
  • Accuracy: ±2 °C typical at 25 °C (check datasheet for full accuracy table)
  • Operating Temperature Range: −40 °C to +125 °C (device rating; consult datasheet for guaranteed limits)
  • Quiescent Current: Typically ~50 µA
  • Output Impedance: Low source impedance suitable for ADC inputs
  • Response Time: Fast response for ambient temperature changes (see datasheet for time constants)
Mechanical Specifications:
  • Package Type: TO-92 through-hole epoxy case
  • Lead Finish: Tin-plated leads for standard soldering
  • Body Material: Molded epoxy suitable for general-purpose sensors
  • Mounting: Fits standard breadboards and through-hole PCBs
Dimensions:
  • TO-92 Typical Body: Standard TO-92 dimensions; refer to manufacturer mechanical drawing for exact values
  • Lead Spacing and Length: Standard through-hole lead spacing compatible with perfboards and PCB footprints
Pinout and Wiring:
  • Pin 1 (left): VCC — Connect to 2.7 V–5.5 V supply.
  • Pin 2 (middle): VOUT — Analog output. Read with ADC. Convert using T(°C) = (VOUT − 500 mV) / 10 mV.
  • Pin 3 (right): GND — Connect to system ground.
  • Wiring Tips: Add a small bypass capacitor (0.1 µF) near VCC for noise suppression. Place sensor away from heat sources and PCB traces to avoid self-heating errors. Use averaging in software to reduce ADC noise.
Datasheet Reference:
  • Download the official TMP36 (Analog Devices/TI) datasheet for full electrical characteristics, accuracy tables, thermal data, and mechanical drawings. Search manufacturer sites for “TMP36 datasheet”.
Applications:
  • Embedded Temperature Sensing: Read ambient temperature with microcontrollers and single-board computers.
  • Battery-Powered Systems: Monitor temperature with minimal power draw.
  • HVAC and Environmental Monitoring: Integrate into thermostats and environmental sensors.
  • DIY and Prototyping: Use on breadboards for hobby projects and education.
  • Industrial Controls: Use in control loops where a simple analog temperature signal suffices.
Equivalent Models:
  • TMP35 / TMP37: Same family with different offsets and ranges.
  • LM35: Common linear temperature sensor alternative (note: different supply and offset behavior).
  • MCP9700 / MCP9701: Microchip low-voltage analog temperature sensor alternatives.
Package Includes:
  • 1 x TMP36 Low-Voltage Temperature Sensor in TO-92 package
