Challenges:

(1) If daylight gets too dark, turn on lights according to a program

• Uses built-in light sensor; LEDs or lamps

(2) Vary lights to make it look like someone is home

• Uses LEDs or lamps or Neopixels, copper tape or wire

(3) Turn on outdoor lights if someone approaches using a PIR motion sensor

• Same as above + PIR sensor

(4) Arm a security alarm if all doors and windows are closed. If armed and door opens, sound alarm& sonalert, and send message to an Internet dashboard.

• Copper tape, aluminum foil, sonalert, 

(5) Water plants if they get too dry

• Moisture Sensor, 5V pump

(6) If temperature exceeds a preset level or upon voice request, turn on a fan

• DC Motor, propeller

(7) Open a door with a servo motor

• Servomotor

Smart Home Kit introduction

Smarthome Kit is a product about smart home project base on micro:bit which is developed by ELECFREAKS.
We selected executed components commonly used at home as TMP36 temperature sensor, sound sensor, crash sensor, servo, motor. You can build scene like windowsill, wardrobe and fish tank, create yourself smart sweet home and programming to intelligently driving them using micro:bit.

Smarthome Kit is what makes life more practical and playing with it is what makes life more interesting.
