ESP8266 based Internet enabled (IOT) smoke and fire alarm to send SMS notification (Twilio) and to trigger alarm with flashing red LED if it detects smoke and leakage of combustible gas using MQ2 gas sensor. Also ThingSpeak analytics is a great bonus....
A home automation project that maps switching on/off of appliances with your entry/exit of a geofence (virtual perimeter for a real-world geographic area). Step into a cool room without having to wait for the air conditioning to start functioning? Watch the garage door open as you drive in....
This is my first post on home automation. As a 'Hello World' project, switching on/off a bulb is a common use case. This post is not an exception. But to spice it up, we'll use MQTT (MQ Telemetry Transport) - a machine-to-machine (M2M)/Internet of Things (IOT) connectivity protocol...
ESP8266 can act as both Station / WIFI client (STA_IF interface) and Access Point (AP_IF interface). AP_IF interface is active by default in MycroPython firmware on ESP826 . In the earlier post, we connected to the access point (AP mode) of ESP8266 and used WebREPL to remotely control switch...
So far, we have flashed MicroPython firmware onto an ESP8266 and setup WebREPL to run programs over WIFI on the chip. Now it's time for a hands-on excercise. We'll remotely switch on/off and control brightness of an LED using MicroPython WebREPL....
