The code provided by [Shyam] reads the humidity and temperature data from the DHT11 sensor, and “writes” it to the Blynk service.

And by using a second BBC micro:bit, we can get the readings before heading outside. First, we need a DHT11 sensor, and to check whether it works using one micro:bit.

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino.

Kudos go out to [Jose] for his work getting so many different components to talk to each other in this Arduino weather station that using a Raspberry Pi to display the data online. The components s… ...
