Send data (temperature and humidity) to the Thingspeak site with Micro:bit

Purpose of this project:

Thanks to the Micro: bit card and the ESP8266 module connected to the Internet of Things (IoT: Internet of Things), it is possible to monitor in real time the temperature and humidity measured by the DTH11 sensor.

To create sensor data recording applications, you can use ThingSpeak which is an API and an open source application for the Internet of Things, allowing you to store and collect data from connected objects.

Necessary components

• Micro:bit
• ESP8266 module
• DTH11 sensor

• Connecting wires

Mounting:

To perform the assembly

For ESP8266 :

• the RX pin to Pin P0 of the Micro:bit card

• the TX pin to Pin P1 of the Micro:bit card

• the GND pin to the GND of the Micro:bit card

• the two pins 3V3 and EN to the 5V pin of the power supply module

For DHT11 sensor:

• the DATA pin to P2 of the Micro:bit card

• the VCC pin to the 3.3V pin of the Micro:bit card

• the GND pin to the GND pin of the Micro:bit card
