The reflective module with IR sensor is equipped with digital and analogue output. It works with a voltage from 3 V to 5.3 V. It enables the detection of obstacles in the range from 0 to 30 mm.

An infrared sensor contains two parts: an infrared transmitter and an infrared receiver, the infrared transmitter consists of an infrared LED array as a luminophore and a PN junction made of a special material with high infrared radiation efficiency, which usually is GaAs. When a current injected into the PN junction by forward bias voltage, it can excite a source of infrared light with a center wavelength range of 830nm-950nm. The power of the infrared light excited is proportional to the current injected. However, in the case that the injected current excesses the maximum rating, the power of the infrared light may decline as the current increases. The infrared receiver is a semiconductor device for translating the infrared light signal into the electrical signal. And the core component of it is a PN junction made of a special material. Its PN junction has a different structure from the general purpose diode, enabling more infrared light to be received. As the
intensity of the infrared light enhances, more current can be generated.

The MR60BHA1 60GHz radar module implements personal breathing rate and heart rate detection based on Frequency Modulation Continuous Wave(FMCW) detected theory, providing a fully private and secure environment, independently from other noisy influences. Additionally, with built-in a standard algorithm and onboard antenna, the unit ensures simultaneous signal output in high accuracy. It represents an ideal solution for high-accurate, self-regulation, privacy-protected, secure biotic radar systems in consumer electronics, healthcare as well as industrial applications. 

Because the range resolution is heavily dependent on available bandwidth, 60 GHz mmWave sensors will offer significantly better performance than 24 GHz sensors for high-accuracy and reliable object identification. Meanwhile, 60 GHz mmWave sensors gather rich point-cloud data as it is critical to maintain high measurement accuracy for respiratory and heartbeat scenarios. As the radar works mainly on the basis of the respiratory heart rhythm causing undulating movements on the surface of the large muscles through 60 GHz mmWave, the undulation of the human chest and back will be more pronounced

The MR60BHA1 radar leverages the fine performance of 60 GHz FMCW and utilizes an intelligent processing algorithm to achieve the high-accuracy output, as 85% of heartbeat detection and 90% of breathing detection. Furthermore, the radar can be independent from temperature, humidity, noise, airflow, dust, light, and other environmental influences. Designed as low power output, the radar maintains health-friendly working status while it is observed. For privacy protection, the radar provides a perfect solution that applies FMCW monitoring technology to equip surveillance capabilities without identification.

The radar supports secondary development and it adapts to various scenarios applications. Using a universal UART communication interface provides an extra common protocol as 4 groups of IO that are reserved by the user’s definition. The detected area is a three-dimensional sector of 80° horizontally and 80° tilted and the measured distance is between 0.4-2 m.

This microwave sensor is a microwave module that can transmit an electromagnetic wave of 5.8GHz. It can detect the difference between the transmitted wave and the reflection wave to identify whether there is an object moving in the detection area.

Different from the traditional sensors that can only detect human presence by detecting big body movements, this microwave sensor can perform well in detecting small movements like breathing so as to determine human presence even if the person is sitting or sleeping. The detected result can be output through the serial port or high/low level of the I/O port. Featuring high reliability and sensitivity, and strong anti-interference, it is small and easy to integrate, which can be widely used in fields that require motion detection, such as lighting, security, home, home appliances, hotels, garages, buildings, traffic, etc.
