In recent years, sensor technology has been used increasingly to make advancements in countless fields. Among them, the specialized sensors can be particularly useful for tasks such as medical diagnostics, industrial automation, and environmental monitoring. BH1792GLC-E2 is an example of such a specialized sensor, which is designed for measuring heart rate and respiration rate for medical diagnostics. This article will discuss the application field and working principles of the BH1792GLC-E2.

Generally speaking, the BH1792GLC-E2 is used for measuring heart rate and respiration rate from human tissue. It is a single-chip optical heart rate/respiration rate sensor with integrated analog front-end, signal processor and LED driver. It is powered by a 3.3V power supply and supports I2C communication protocol. The two sensing LEDs emit NIR lights of different wavelengths to measure human tissue’s absorption of oxygen. It also contains two photodiodes to detect the reflected lights and convert them into electric signals, which will then be amplified and filtered by the signal processor.

The BH1792GLC-E2 is designed for medical purposes, mainly for monitoring heart rate and respiration rate of human bodies, and it is suitable for both adults and children. It is usually applied to healthcare, fitness, medicine, and homecare. It can be used in robotic systems, IoT wearables, hearing aids, and other applications related to medical diagnosis. It can also be used in the industrial field, such as industrial automation. For example, it can be used to monitor the working parameters of industrial machines or robots, or for environmental monitoring such as air quality check.

The BH1792GLC-E2 is composed of two parts: the LED part and the signal processor. The LED part consists of two low-power visible or near-infrared LEDs and two photodiodes, which are used for sensing a person’s respiration and heart rate. The two LEDs emit different wavelengths of light which are then reflected by the human tissue and then detected by the photodiodes. The signal processor then amplifies these signals and filters out any noise. The signal is then sent to a host system, such as a microcontroller, which then analyzes the signal for respiration and heart rate readings.

The BH1792GLC-E2 is a highly accurate and sensitive sensor. Its accuracy is ±2 bpm, and it can detect beats as low as 18 beats per minute. The signal processor also performs signal amplification and baseline stability control to ensure the accuracy of the data. Furthermore, the BH1792GLC-E2 is a low power system, consuming only 2mW when in operation and 0.5µW in standby mode.

In conclusion, the BH1792GLC-E2 is a specialized sensor used for measuring human heart rate and respiration rate, and is suitable for medical diagnostics, industrial automation, and environmental monitoring. It is composed of two parts: the LED part and the signal processor, which work together to accurately detect the signal from the human tissue. It is an accurate, reliable and low-power system. By using BH1792GLC-E2, it is possible to have precise and real-time monitoring of human body parameters, which will open up new possibilities for medical diagnoses, industrial automation and environmental monitoring.
