MAXREFDES117# is an evaluation board that enables designers to evaluate ultralow power performance, features and accuracy of Infineon’s High Precision Environment Sensor (HPES). The MAXREFDES117# is a development platform that includes both an HPES sensor and application board for high accuracy and low power measurements. HPES is a combination of temperature, humidity and pressure sensors in a single package. Its breakthrough low power consumption makes MAXREFDES117# a compelling solution for energy efficiency purposes. The sensor is especially designed for industrial and consumer applications.MAXREFDES117# is designed with Infineon’s HPES sensor, which is housed in an LGA package measuring just 4.9 x 5.7 x 0.9 mm. It features a high accuracy temperature sensor, relative humidity sensor, pressure sensor as well as a digital conversion module for signal processing. It also includes a high linearity microphone, an onboard temperature and humidity sensor, and a differential pressure sensor.MAXREFDES117#’s application field includes indoor air quality monitoring, industrial process control, medical diagnostics and disaster early warning systems. The board’s special design allows measurements for temperature, humidity and pressure accurately and with ultralow power usage. With the inclusion of a digital microphone, it can be used for sound-based signal processing applications. The working principle of MAXREFDES117# is based on the principle of ‘converting environmental energy into electrical signals’. The HPES components feature a unique combination of internal events such as microphonics, differential pressures, and temperature/humidity changes. When these events happen, their energy is converted into electrical signals, which are then detected by the sensors and used to derive useful information about the environment.The MAXREFDES117# features Infineon’s HPES sensor components with high accuracy and low power consumption. This board also offers a range of specialised features for environment sensing and signal processing: • Internal conditioning and calibration for reliable operation• Internal low power temperature and humidity sensor• Precision pressure sensing from 0 – 1.2 bar• Maximum differential pressure of 1.2 bar• Minimum sample rate of 1Hz• Maximum sample rate of 100kHz• Microphone level sensing and signal filtering• Programmable measurement range• Digital signal processing for low-frequency signal detectionThe MAXREFDES117# board also features both standard and advanced configuration options. The standard version includes a battery or USB powered processor, HPES and sensor boards, a data logger, and optional Wi-Fi connectivity. The advanced version adds an onboard 95dB microphone, digital signal processing, an inertial measurement unit (IMU), and natural language processing (NLP) support.In conclusion, MAXREFDES117# is an application board that enables designers to easily evaluate Infineon’s high precision environment sensing technology. The board’s features and accuracy allow it to be used for a variety of different applications including indoor air quality monitoring, industrial process control, medical diagnostics and sound-based signal processing. The board includes a range of tailored features such as internal sensors, precision pressure sensing, digital signal processing, and Wi-Fi connectivity. With its ultralow power consumption, the MAXREFDES117# provides an attractive solution for designers looking for reliable and accurate environment sensing.
