People possess the ability of sensing their environments, including the senses of sight, hearing, touch, taste and smell. When we use these senses naturally, we can make responses to the change in our environments. If we want machines to respond to a change in environments, we will need to program them with corresponding sensing abilities. This will be helpful in the applications of sensors. Sensors are more sensitive than people, and can surpass them by making real-time responses.
Smart control plus sensors can make products smarter
The most frequently seen sensors are those detecting temperature, humidity, ultra-violet, air pressure, radar module, and gestures. These kinds of sensors can detect the changes in environments, feeding back information to the control module. Then, the control module is able to make corresponding functional processing.
Regarding the applications of these sensors, Arrow ESC has launched various kinds of corresponding control modules and sensor daughter cards. We can also help our customers to integrate and develop their products. The sensors are introduced as follows.
Arrow ESC provides the QCA smart control module, including the Qualcomm QCA4002-AL3X chip, which is a system chip with build-in 802.11 b/g/n wireless function. It can transmit and receive in single stream, and is highly suitable for low frequency embedded applications. It has also integrated the network processor and high efficiency microcontroller STM32F411CEY6. With high-speed embedded memory, it works with sensor daughter cards to conduct intelligent control function in embedded applications.
ST HTS221 temperature/humidity sensor is a matching daughter card of an intelligent control module. Neat in size, it can sense the relative temperature and humidity in the environment. Covering the relative humidity from 0~100% and temperatures from -40℃~+120℃, it is suitable for the applications in air-conditioners, refrigerators, wearable devices, home automation, factory automation, and more.
Vishay VEML6070 is an ultra-violet sensor. This single chip has integrated optoelectronic diode, amplifier, and analog and digital circuits. With the ability of detecting the ultra-violet in the environment in full scale, it is suitable for use in ultra-violet senor, cosmetics, outdoor wearable devices, and consumer products.
Infineon DPS310 is an air pressure sensor, with high accuracy and ultra-low electric consumption. Even if it is situated in a fluctuated humidity environment, it can still detect air pressure accurately. It can detect pressure from 300 to 1200 hPa. The compact size is highly suitable for use in mobile applications and wearable devices.
Infineon BGT24MTR11 is a 24GHz radar daughter card. Its radio frequency includes BGT24MTR11 24GHz radar MMIC and microstrip patch antenna, suitable for receiving and transmitting signals. Its digital capacity includes a XMC4200, which is a 32-bit ARM Cortex-M4 microcontroller, suitable for use in processing the sampling and processing RF front-end analog signal. It can also be used in configuring BGT24MTR11 chip. This daughter card can be used in motion detection, auto devices, the internet of things and security applications.
Vishay VCNL4020 is an integrated gesture control sensor. It can detect the changes in gestures, and provide non-contact operating experience. It is highly useful when users are wearing gloves or with dirty hands that make contact with the touch screen panels inconvenient. With a built-in 16-bit resolution infrared transmitter, it has integrated circuits for signal processing and a standard I2C interface with interrupt functions. It is suitable for use in consumer, computers, industrial devices, mobile devices, displays, light detection in keyboards, and dimming controls.
With all the sensors and modules mentioned above, Arrow ESC can provide active support to help customers to complete product development in the shortest time to seize opportunities in the market.
