DHT22-MQTT-Sensor-ESP8266 (NodeMCU) download

This is a Sketch for the arduino IDE to enable the usage of a DHT22 sensor connected to a NodeMCU (ESP8266) with MQTT. Also supported are 2 status LED's and a SPI diaplay.

After start the sensor device, there will be a Wifi-AP for configuration purposes. After successfully configuration, the sensor is connected as a Wifi-client and send the temperature and humidity data via MQTT within the given intervall.

During AP-mode and client-mode, there are some RESTful functions (HTTP-requests) available, for configuration and retrieving information.

Features

MQTT data transport to broker
RESTful functions (HTTP-requests)
Configuration via Wifi-AP
