NodeMCU_sensor

IOT project using NodeMCU, raspiberry pi, MQTT and more!

Feauture:

When the door sensor is triggered, send mail to notify me.

Hardware:

NodeMCU -- a firmware based on ESP8266 wifi-soc Raspberry pi

Software:

Arduino IDE

Deploy:

  1. Install mqtt on Raspberry pi
sudo apt-get install mosquitto mosquitto-clients
  1. Test MQTT on Raspberry pi
mosquitto_pub  -t "ESP8266/sensor/door" -m "{LED: OFF}"
  1. Install MQTT package for python3
sudo pip3 install paho-mqtt

  1. Change the connection info accordingly, such as ssid password... Flash esp8266_door_sensor.ino into NodeMCU

  2. Back to Raspberry pi, run the script

python3 mqtt_sensor_sub.py
  1. On NodeMCU, connect D1 (GPIO5) to GND to simulate the door closed status and disconnect to simulate the opened status.
