It's a basic temperature sensor, not the highest precision in the world, only ±2°C but it will get the job done when you need simple temperature logging or monitoring.\u003c\/p\u003e\u003cp\u003eWiring it up is easy, pin 2 is SDA, middle pin is GND, pin 4 is SCL and the rightmost pin 5 is VDD. You can power it with 3.3 or 5V logic so it's good for any microcontroller or microcomputer. \u003cstrong\u003eNote you will need to add I2C pull-ups on your breadboard\u003c\/strong\u003e especially if your I2C controller does not have them built in already\u003c\/p\u003e\u003cp\u003eFor Arduino code, you can use our PCT2075 library (this chip and that library both use the same LM75 compatible code). For CircuitPython or Python 3, our Python PCT2075 library will work as well. These sensors work best on buses with slow I2C speeds like 100KHz or 400KHz.\u003c\/p\u003e\u003cp\u003eComes as just one through hole sensor.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003cli\u003e\nDatasheet \u003c\/li\u003e\n\u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":54079466078319,"sku":"mdv1787257852749","price":1.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/3376\/0111\/files\/breadboard-friendly-i2c-temperature-sensor---tc74a0-tc74a0-50vat_1.jpg?v=1787257861","url":"https:\/\/popwearboutique.shop\/products\/breadboard-friendly-i2c-temperature-sensor-tc74a0-tc74a0-50vat","provider":"My Store","version":"1.0","type":"link"}
