How To Monitor Temperature With a Raspberry Pi Pico

of raspberry pi pico An ideal way to get into microcontrollers. Boards start at $4 and are cheap and easy to use. Low cost and ease of use means you can easily drop it into your project without fear of the worst of your wallet.

This how-to uses a Raspberry Pi Pico to capture live temperature data using the DS18B20. These sensors come in many forms, from bare transistor chips to waterproof cables. We use the latter version, which can be partially submerged in liquid to monitor temperature. Our project reads the temperature and uses a conditional test in MicroPython to trigger a blinking LED when the temperature drops below 20 degrees Celsius.
