BH1790GLC-EVK-001

The BH1790GLC-EVK-001 is a multi-functional sensing evaluation board. It integrates a high-precision analog front end with integrated Column Driver and Measurement Channel for an accurate and flexible solution. The evaluation board provides support for an extended range of sensing elements such as optical and pressure sensors, temperature sensors, electrocardiogram (ECG) and photoplethysmogram (PPG). The complete measurement platform with an integrated data acquisition system (RIS) allows for easy and efficient experiments using different types of sensors.

The BH1790GLC-EVK-001’s high-accuracy analog front end and integrated Column Driver and Measurement Channel ensure accurate, repeatable measurement of the input signals received from the sensor. The on-board RIS allows to measure up to 8 activity signals, such as ECG, PPG, temperature and pressure, simultaneously, providing a better view and control over physical activity and environment.

Using the integrated components enables easier and faster prototyping of industrial, medical, basic and environmental sensing applications. The comprehensive development and testing environment for the BH1790GLC-EVK-001 boards allow fast and easy modification of the system to suit custom requirements.

For remote monitoring and other applications, the BH1790GLC-EVK-001 offers a range of wireless communication options. An integrated Bluetooth low energy radio and Wifi can be used for communication, data storage and remote control. The built-in communication module can be used to send data and control alarms via smartphone or online portal. Furthermore, the on-board accelerometer can be used for motion detection and monitoring.

The primary applications of the BH1790GLC-EVK-001 include development of physiological monitoring systems such as ECG, PPG, temperature and pressure monitors, environmental sensing systems such as air quality detectors, and industrial sensing systems such as humidity, light and motion sensors.

The working principle of BH1790GLC-EVK-001 consists of three interconnected parts: (1) the analog front end, (2) the column driver-measurement channel circuit, and (3) the data acquisition system (RIS). The analog front end (AFE) is responsible for receiving and processing the signal from the sensor and providing it to the next stage. The Column Driver (CD) and Measurement Channel (MC) together form the MC/CD circuit, which translates the analog signal from the AFE stage into digital data. Finally, the RIS is responsible for storing and analyzing the data collected from the sensor.

The BH1790GLC-EVK-001 is a flexible and cost-efficient evaluation board ideal for development of applications in the field of environmental and industrial sensing and medical monitoring. The integrated components and modules simplify the development process to achieve faster and more accurate results. The built-in wireless communication modules allow for convenient remote monitoring of the system for maintenance and usage optimization.
