Send Temperature and Humidity Data To ThingSpeak Using micro:bit

Introduction

In this video, it is demonstrated how to send temperature and humidity data to Thingspeak using micro:bit. The connection between the REKA:BIT and other devices are made through the grove connection. The value of temperature and humidity from DHT11 is displayed on the micro:bit display and at the same time the value is sent over to Thingspeak via wifi.

Hardware Preparation

This is the list of items used in the video.

Sample Program

This is a simple program that was developed using the MakeCode for micro:bit. What the program does is that, in the on start block, the wifi is initialized and in the second block which is the forever block, the DHT11 sensor is configured and also the data are displayed on the micro:bit display and sent to the thingspeak. For this project, three different extensions are required the first is the reka: bit, the second is the esp8266 and lastly is the dht11_dht22.
