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.\n\nThe 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.\n\nKey Features\n\n\nAnalog Output – Simple voltage output proportional to temperature, no libraries needed\n\n–50°C to +125°C Range – 0V at –50°C, 1.75V at +125°C\n\n3-Pin JST PH (STEMMA) Connector – Plug-and-play connection with compatible cables\n\n3V to 5V Operation – Compatible with a wide range of microcontrollers\n\nEasy Calculation – Temp °C = 100 × (voltage) – 50\n\n\n\nTip: For the best accuracy on an Arduino UNO or compatible, set the analog reference to external and connect AREF to 3.3V for a stable reference voltage.\n\n\nIdeal For\n\nSimple temperature monitoring projects\nQuick prototyping with analog inputs\nUpgrading from the TMP36 with a plug-and-play connector\nProjects where I2C is unavailable or unnecessary\n\n\nPackage Contents\n\n1× Adafruit TMP235 Analog Temperature Sensor (with JST PH connector)\n\n\n\nNote: A JST PH 3-pin cable is required and is not included.\n\n\nResources\n\nGetting Better Precision with Analog Temperature Sensors\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4094,"title":"Default Title","sku":"AF-4686","price":4.87,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
