Story

The sleep environment plays a key role in sleep quality. Factors such as temperature, humidity, noise, light, and air quality can either support restful sleep or cause disruptions. A room that is too hot, humid, or noisy can make it difficult to fall and stay asleep, while bright lights, especially from screens, can interfere with the body’s natural sleep cycle. Poor air quality may also impact breathing and overall comfort. By optimizing these factors, individuals can create a more restful environment that promotes better sleep and overall well-being.

Objectives:

Monitor the environment using M5Stack sensors to track key sleep environment factors such as temperature, humidity, noise levels, light exposure, and air quality.
Collect and process real-time data to assess how environmental conditions impact sleep quality.
Offer recommendations based on sensor data to enhance the sleep environment, such as adjusting room temperature or reducing noise.

Research:

Sleeping in a dark room improves sleep quality by supporting the body’s natural circadian rhythm.
Even dim light exposure at night can disrupt deep sleep and REM sleep.
High humidity makes breathing difficult and can cause discomfort, while low humidity may dry out nasal passages and lead to snoring.
The ideal room temperature for sleep is around 16-20 Degree Celsius. Too hot or too cold environments can lead to restless sleep.

Project:

Light Monitor: Using the light sensor, we can monitor the amount of light in the room and if it is too bright the motor will move to pull down the curtains to prevent the light from coming into the room.
ENV II sensor: Using the ENV II sensor we can monitor the temperature in the room and if the temperature is too cold or too hot, the servo motor will move to adjust the A/C or fan to adjust the temperature in the room.

Servo Motor: It is used to adjust the different appliances in the room to help regulate the conditions of the environment.
