Emotional Guardian Wearable and Doll is an emotional control device that uses advanced sensor technology to monitor
and analyze the user's physiological data in real time, converting these data into indicators of emotional state.
The core goal of the device is to help people better recognize and manage their mood swings and improve their quality
of life. Using precise measurements from heart rate monitors, skin temperature sensors and skin conductivity sensors,
it accurately captures the user's mood changes. When a negative emotion is identified, the device alerts the user with
soft light and relaxing music, connects to the doll, and provides relaxation guidance and voice prompts for breathing
exercises to help the user quickly calm down.
1.4 Sensors
01.Heart rate monitor: measures the user's heart rate, which can effectively reflect changes in emotional states
such as tension and excitement.
02.Skin temperature sensor: captures an increase in body temperature due to stress or anxiety.
03.Skin conductivity sensor: Measures the activity of sweat glands to further confirm whether the user is in an
emotional or stressed state.
Ideal 2-Rainwater collection device

Goals 6:Clean water and Sanitation
2.2 Sketch
2.3 Introduce
Rainwater collection device:
To help water-stressed areas in developing countries carry out activities related to water and sanitation, devices
for rainwater harvesting and reuse are envisaged.
Source of rain: roof rain, ground rain, direct rain
The device is divided into three parts:
Upper (rain receiving part) : The humidity sensor is connected to the top cover of the device.
Middle (rainwater filtration part) : multi-layer filtration layer is set to filter the rainwater (disinfection)
Under (rainwater storage part) : storage rainwater part, install water quality detector.Add faucet outlet
(for garden irrigation or washing hands, etc.)
The upper unit can be separated from the middle and lower part to facilitate the filtration of ground rainwater
or other water resources.
tips: This device can only ensure that the water quality is up to drinking standards, and can be used for laundry,
irrigation, or other everyday purposes.
2.4 Sensors
01.Humidity sensor:Connect the top cover of the device, when the humidity is too high, open the cover to receive rain
(reduce evaporation or pollution when it is not raining)
02.Water quality detector: In the storage rainwater part, install water quality detector, green light when the water
quality is up to standard, red light when the water quality is not up to standard, reminding people to replace the
filter layer
03.Water level sensor: When the water level below is detected to be too high, send a signal to the top cover to close
the cover.

3.3 Introduce
With the development of The Times and the progress of science and technology, the creatures who share weal and woe with
us have also been greatly affected, some are not adapted to the impact of human beings and are on the verge of extinction,
and some are completely dependent on human help and reproduction, which is not conducive to the biodiversity of the earth,
the earth is the common home of all living things, as human beings, in the rapid development of civilization, we must
share weal and woe with the life on earth
3.4 Sensors
01-Water turbidity, pH sensor：
1. STM32F103CT6 MCU is used as main control.
2. The PH sensor is converted into a digital display through the internal AD.
3. Use turbidity sensor to collect water turbidity 4.0.96 "0LED liquid crystal display current TDS, temperature, PH and
turbidity data.
02-Temperature and humidity detection and alarm system：
1.The temperature and humidity sensor uses DHT11. The temperature ranges from 0 to 50 degrees, and the humidity ranges
from 10% to 95%RH.
2.There are four indicators, indicating that the temperature is too low, the temperature is too high, the humidity is
too low, and the humidity is too high. The buzzer alarms and the corresponding indicator lights up.When the temperature
is too high, the analog cooling device starts and the relay controls the rotation of the small fan.
03-Total monitoring and control system：
1.OLED screen displays temperature, water level and water quality.
2. The DS18B20 temperature sensor measures the temperature. When the temperature is too low, it heats up and stops heating
when the heating reaches the upper limit.
3. Water level detector, water level is too low automatically add water, water to reach the upper limit stop adding water.
Water quality tds test triggers automatic water change.
4. Light sensor detects light and automatically fills LED fill lighting.
5. Connect to the cloud platform through Wi-Fi, send remote data to the mobile phone, and view data and remote control.

Blood sugar grip tester ：As aging becomes more and more serious, diabetes has become a major health problem for the elderly,
our blood glucose meters today require needles, and elderly people living alone are difficult to complete this operation alone.
In order to measure and solve this problem, a blood glucose grip tester for the elderly was designed, which can detect blood
glucose levels through infrared sensors, thus eliminating the need for blood collection. In addition, the device is equipped
with sensors that can monitor the elderly's grasp and handshake ability to detect whether they are healthy.

cutlery detector:As the elderly are alone at home and do not pay attention to healthy diet, they often eat overnight meals,
which has a great impact on their health. The design of the cutlery food detector can sniff out the gas released by rotten
food and monitor whether the food is spoiled according to its freshness with a sensor on the upper end of the cutlery handle.
If the food goes bad, the cutlery detector will vibrate to warn the display above the cutlery to emit a red light. If very
fresh, it will glow green.
