Nowadays, sensors have integrated into all corners of our lives, which can analyze our daily behavior, increase our interaction with the world. For example, we often come into contact with motion sensors, temperature and humidity sensors, and the like. With some common intelligent sensors, you can greatly enhance the convenience and safety of your life.
In the most popular smart home design of the Circuit City, we can see the design of small rice bracelets, air purifiers, toxic gas detection, etc. These hot applications are inseparable from the work of the sensor.
Sports sensor perceived people and things - millet bracelet design
For motion sensors, everyone will not be unfamiliar, it allows you to understand at home or around, once some "wind blowing" it will send the warning information to the owner's mobile phone.
Program introduction: Millet bracelet design of the circuit city open source, function has basic step, sleep monitoring, calorie calculations, but also helps users complete daily exercise. The main chip uses Taiwan's Huabang Electronics W25Q80BV (W25Q80BV data sheet), the sensor adopts ADI's three-axis MEMS acceleration sensor ADXL362 (ADXL362 data manual), Bluetooth chip uses Dialog's DA14580 (DA14580 Data Manual) Bluetooth SOC.
Temperature and humidity sensor creates a comfortable environment - multi-function air detector (formaldehyde, PM2.5, temperature and humidity detection)
Suitable temperature and humidity can also bring a comfortable living environment for users. Although some electrical equipment also have a temperature and humidity probe, after all, the range of monitored has limited range, it is difficult to monitor each corner in home, so the temperature and humidity sensor can make up for this missing, Bring a full range of environmental feedback to love the family to create a comfortable living environment.
Program introduction: Multi-functional air detectors made by circuit city open source, more and more practical. Air testing is mainly divided into the following aspects: formaldehyde detection, PM2.5 detection, temperature and humidity detection (SHT20 sensor), time, ESP8266 network, TFT display.
Smoke sensor protects the whole home safety - home gas alarm
Smoke sensors are generally applicable at home, while commercial use is wide. But it can also bring safety for home users. Before the fire happens, it is a user warning. When it detects a smoke, immediately trigger the electrical switch in the home to make a power-down action, and reduce the loss.
Program introduction: The design of the household gas alarm design of the circuit city is designed to use the Renesas MCU R7F0C802 as the main control chip, and the TGS5042 is used as a CO sensor to achieve a home gas alarm function. The alarm concentration / time, using EN50291 European or US standard design; gas alarm: 3 meters high scape the alarm (>85dB), red LED flash fast.
Air Sensor for Health Air Guard - Intelligent Car Air Purifier
The air sensor can monitor the monitoring environment in real time. Once the safety metrics can trigger the air purification equipment in the home, purify the air, create a healthy air environment for your family.
Program introduction: The vehicle air purifier design of the circuit city, using STM8S003F3 as the main control chip, using the Fero TGS2600 air quality sensor to detect the car environment, using the air quality indicator to indicate the current air quality. The air purifier has a key start, monitoring the air quality and automatically purifying in real time. At the same time, for interior pollution / formaldehyde TVOC super-scent second-hand smoke residual PM2.5 virus, the deep purification removal, releases thousands of high concentrations of negative ions, improves air quality in the car, providing users with healthy driving environment.
Harmful gas sensors are kept away from potential hazards - controller toxic gases (CO \ SO2, etc.) testing solutions
Carbon monoxide poisoning, flammable gas leakage, etc. Time to endanger people's personal safety, while harmful gas sensors can act as "bodyguards" for their families, and always detect harmful gases in the air. Once a toxic gas is found, an alarm can be issued immediately, and can be linked to the exhaust fan or window in the home, and the exhaust fan is triggered and the ventilation window is triggered.
Program introduction: The toxic gas testing plan for circuit city open source provides a carbon monoxide gas detection scheme based on ADI ADUCM360 (ADUCM 360 Data Sheet) MCU. The concentration of hazardous gas Co exposed to an environment can clearly read the gas concentration, peak, and high, low concentration alarm level. If the current gas is high, the low concentration value exceeds the preset limit value, the instrument will remind the user with sound and light alarms.
