The Adafruit TMP235 is a plug-and-play analog temperature sensor with a 3-pin JST PH (STEMMA) connector. Unlike I2C sensors, this one outputs a simple analog voltage proportional to temperature — just connect it to any microcontroller with an analog input and read the value. No libraries or complex configuration required.

The sensor measures from –50°C to +125°C, outputting 0V at –50°C and 1.75V at +125°C. Converting to temperature is straightforward: Temp °C = 100 × (reading in V) – 50. It runs on 3V to 5V and connects via any 3-pin JST PH cable — red to power, black to ground, white to analog input.
