A 'smart house' integrates sensors, microcontrollers, and actuators to automate everyday tasks, improve energy efficiency, and enhance security. Rather than relying purely on manual switches, a smart system makes decisions based on environmental data. In addition, a smart house permits environmental and security functions to be viewed and controlled remotely, as an example of the 'Internet of Things'/
The Smart Homes project has participants create a functional model of a ‘smart house’, that incorporates automated systems based around the Microbit microcontroller and assorted sensors, lights, motors, and pumps.
This is a fairly ambitious project, as it involves a multiplicity of sensors, actuators, controllers, and drivers.
Key Categories of Smart Home Devices
Smart Lighting: Products like the Philips Hue Bridge Pro let you adjust brightness, change colors, and set schedules. [1, 2]
Home Security: Devices like video doorbells, smart locks (such as the Aqara U400 or Nuki Ultra), and cameras keep your property safe with real-time alerts. [1, 2]
Climate Control: Energy-efficient options like the Google Nest Learning Thermostat (4th gen) learn your routine to save on heating and cooling bills. [1]
Smart Displays and Hubs: Devices like the Amazon Echo Show 8 act as central control panels for your entire ecosystem. [1]
Sensors: Motion, temperature, and water leak detectors drive home automation by triggering specific actions when changes occur. [1, 2]
Day 1: What is a smart home? Define sensors and actuators
Day 2: Wire and Connect lights, buzzers, servos, sensors, fan; extend wires to control box
Day 3: Code house functions
Day 4: Assemble Smart House
Level 1:
Climate Control: When the temperature sensor on the Microbit exceeds as threahold, Heat will be simulated with red Neopixels, and the fan will be turned on.
Climate data will be read using a BME280 sensor, and displayed on an LCD Screen.
Automated Security: Motion sensors detecting an approaching person and triggering a servomotor to lock a deadbolt while sending a notification.
Adaptive Lighting: Ambient light sensors detecting dusk and automatically turning on Neopixel porch lights to a specific brightness.
Level 2: Add Voice Control and Remote Monitoring and Control
Voice control is used to operate house functions
House system sensor status is uploaded to a web-based IOT platform(Thingspeak)
