Description

The Adafruit TMP235 is a precision analog temperature sensor designed for simplicity and ease of integration. It converts ambient temperature into a linear voltage signal, eliminating the need for digital communication protocols and complex libraries. This makes it ideal for educational projects, rapid prototyping, and systems where a straightforward analog signal is preferred.

The sensor operates on a 3V to 5V DC supply and features a built-in STEMMA JST-PH connector, compatible with a wide range of plug-and-play cables from Adafruit. Its output is directly proportional to temperature, allowing for simple calculation (Temp °C = 100 * Vout – 50) on any microcontroller with an ADC. The module is RoHS compliant and designed for reliable performance in standard electronic environments.

Key Features

  • Linear Analog Interface: Provides a direct, library-free voltage output proportional to temperature for simple ADC reading.
  • STEMMA JST-PH Connector: Standardized 3-pin plug-and-play connector enables quick, solder-free connections with compatible cables.
  • Broad Power Compatibility: Supports a wide 3V to 5V DC input range, making it compatible with most microcontroller development boards.
  • Simplified Integration: Requires no external components, calibration, or complex software drivers for basic operation.
  • RoHS Compliant Construction: Manufactured with lead-free and environmentally safe materials.
  • Compact Form Factor: Small PCB footprint allows for easy integration into space-constrained projects and enclosures.

Applications

  • Microcontroller-based temperature monitoring for educational STEM kits and beginner electronics projects.
  • Environmental sensing in simple data loggers and weather stations using analog inputs.
  • Thermal monitoring for enclosures, prototypes, and basic industrial control systems requiring a direct voltage signal.
  • Rapid prototyping and proof-of-concept builds where I2C/SPI complexity is undesirable.

Frequently Asked Questions

How do I connect and read data from the TMP235 sensor?

Connect the sensor's STEMMA connector to a compatible 3-pin cable. The red wire connects to a 3V-5V DC power source, black to ground, and white to an analog input pin on your microcontroller. Read the analog voltage and convert to temperature using the formula: Temperature (°C) = 100 * Voltage (V) - 50.

What is the operating voltage range and output signal of the TMP235?

The TMP235 operates from 3V to 5V DC. It provides a linear analog voltage output, where 0V corresponds to -50°C and 1.75V corresponds to +125°C. The output is ratiometric, meaning its scale is consistent across the valid supply voltage range.

Does this sensor require any libraries or special calibration?

No, the TMP235 is a purely analog sensor and does not require any software libraries or initial calibration. The voltage-to-temperature relationship is linear and defined by its datasheet, allowing direct calculation from the ADC reading on your microcontroller.

What microcontrollers is the TMP235 compatible with?

It is compatible with any microcontroller or development board featuring an analog-to-digital converter (ADC) and operating within the 3V-5V logic range. This includes Arduino boards (Uno, Mega, Nano), ESP32, Raspberry Pi Pico (using its ADC pins), STM32, and many other platforms.
