Internet Enabled Night Light. I made this out of an old wall wart and an ESP8266 SOC module. Basically took the guts out of the wall wart and replaced them with the contents of a much more modern wall wart (smaller) which left space for the ESP8266 module, the PIR sensor and other bits. The device uses MQTT to communicate trigger events and periodic measurements to a custom cloud service.

  • Temperature - DHT11
  • Humidity - DHT11
  • Brightness - LDR (Light Dependent Resistor)
  • Movement - PIR Module (DSN-FIR800)

ESP8266 Prototype Breadboard

Here is a small ESP8266 prototype using a DHT11 and an LDR for light level sensing. This module is super convenient; it has USB to RS232 integrated and also has standard spacing so it can be put into a bread board.

The kids broke their iPad charge cable. They are not too hard to repair. I backed up the connector with a piece of cable tie as strain relief and heat shrunk it all together.
