Next-Gen Connectivity: Analog Front End Sensor & Low Energy Bluetooth

In the fields of industrial, medical, and scientific applications, precise electrochemical measurements are crucial for accurate data analysis. The CEM102 Analog Front-End (AFE) is specifically designed to bridge the gap between sensor networks and digital processing, ensuring that the right signals are delivered to the electrodes for optimal sensor conditioning and highly accurate measurements.
 
The CEM102 excels in continuous glucose monitoring (CGM) and other amperometric applications, where sensing extremely low currents is essential. Its compact design and low power consumption make it an ideal choice for applications requiring further miniaturization and extended battery life. Paired with the onsemi RSL15 (Secure Bluetooth^® 5.2 wireless MCU), it brings significant system-level advantages, including optimized power consumption and a versatile supply voltage range from 1.3 to 3.6 V, compatible with a 1.5 V silver oxide battery or a 3 V coin cell.

Kickstart your development process with the CEM102 evaluation board, which includes the RSL15 and sample code to quickly set up and begin measurement activities.
