How To Monitor Temperature With a Raspberry Pi Pico

Posted on

The Raspberry Pi Pico is the perfect approach to get into microcontrollers. Ranging from $4, the board is affordable and straightforward to work with. The low value and ease of use means we will simply drop them right into a venture with out fearing the worst for our pockets.

On this how-to, we are going to use a Raspberry Pi Pico to seize dwell temperature information utilizing a DS18B20. This sensor is available in many kinds, from a naked transistor chip, to a water-proof cable. We’ll be utilizing the latter model, which could be partially submerged in a liquid to watch the temperature. Our venture will take a temperature studying and utilizing a conditional check in MicroPython it’s going to set off an LED to flash if the temperature goes beneath 20 levels Celsius.

The circuit is made up of two components. The DS18B20 temperature sensor, and the LED. We’ll break them down into two sections.
