The DFROBOT C1001 60GHz mmWave Indoor Fall Detection Sensor is designed for precise human presence, fall, and sleep monitoring. Utilizing 60GHz millimeter-wave radar technology, this sensor offers advanced capabilities for detecting human posture, movement, and vital signs without requiring physical contact. It is compatible with development platforms such as Arduino, ESP32, and Micro:bit, making it suitable for various embedded applications.

2. Карактеристике производа

• Accurate Fall Detection: Implements human posture recognition through point cloud imaging algorithms to accurately detect falls.
• Precise Life Detection: Offers precise life detection, accurately reporting on fall status, duration of stay, and stationary body status.
• Праћење сна: Perceives human biological presence and movement, continuously recording human presence. Based on changes in body movement and breathing heart rate during sleep, it makes real-time judgments on the target's sleep status and breathing heart rate. After a period of sleep, it outputs a sleep score, which can be incorporated into health monitoring applications.
• 60GHz mmWave Technology: Provides high-resolution detection capabilities for indoor environments.
• Широка компатибилност: Designed for integration with popular microcontrollers like Arduino, ESP32, and Micro:bit.

4.1 Опис Пиноут

The C1001 sensor module features several pins for power, ground, and communication. Understanding the pinout is crucial for correct integration with your development board.

Figure 4.1: C1001 Sensor Pinout.

• ВИН: Волtage Input (Power Supply). Connect to the 3.3V or 5V output of your development board.
• ГНД: Ground. Connect to the ground pin of your development board.
• РКС: Receive Data. Connect to the TX pin of your development board for serial communication.
• ТКС: Transmit Data. Connect to the RX pin of your development board for serial communication.
• IO1, IO2: General Purpose Input/Output pins. These may be used for specific control or status signals depending on the firmware and application.

4.2 Повезивање хардвера

To connect the C1001 sensor to an Arduino UNO or ESP32 board, follow these general steps:

1. Повежите ВИН pin of the C1001 sensor to the 5V (for Arduino UNO) or 3.3В (for ESP32) pin on your development board.
2. Повежите ГНД pin of the C1001 sensor to a ГНД pin on your development board.
3. Повежите TX pin of the C1001 sensor to the RX pin (e.g., Digital Pin 0 for Arduino UNO, or a designated RX pin for ESP32) on your development board.
4. Повежите RX pin of the C1001 sensor to the TX pin (e.g., Digital Pin 1 for Arduino UNO, or a designated TX pin for ESP32) on your development board.
5. Ensure a common ground connection between the sensor and the development board.

Note: Specific pin assignments for RX/TX on ESP32 or Micro:bit may vary. Refer to your development board's documentation for recommended serial communication pins.

4.3 Конфигурација софтвера

To utilize the C1001 sensor, you will need to implement appropriate software on your chosen development platform.

• Библиотеке: DFROBOT typically provides libraries for their sensors. Тражи "DFROBOT C1001 library" for Arduino IDE or PlatformIO.
• Серијска комуникација: The sensor communicates via UART (serial). Initialize a serial port on your microcontroller at the correct baud rate (refer to the sensor's datasheet for the default baud rate).
• Тумачење података: The library will handle the parsing of data received from the sensor, providing high-level information such as fall status, presence detection, and sleep parameters.

5. Упутство за употребу

5.1 Fall Detection

The C1001 sensor continuously monitors the environment for human presence and posture. When a fall event is detected, the sensor's internal algorithms analyze the point cloud data to confirm the fall. The sensor will then output a signal or data indicating a fall status, along with information on the duration of stay in a fallen or stationary position.

5.2 Надгледање спавања

For sleep monitoring, the sensor tracks subtle movements and vital signs (breathing heart rate) of a person during sleep. It can differentiate between various sleep states and provide real-time judgments. After a period of monitoring, it can generate a sleep score based on collected parameters, which can be integrated into health monitoring applications.

5.3 Detection Range and Placement

The sensor has a maximum detection range of 11 meters. For optimal performance, consider the placement of the sensor to cover the desired area. The fall detection range and human body stationary/trigger ranges are typically conical, extending from the sensor.
