Capacitative Fingerprint sensor

High‑Resolution 1.2 mm × 1.0 mm Capacitive Fingerprint Sensor

The Netro Capacitive Fingerprint Sensor employs multi‑point capacitance sensing to capture high‑detail ridge‑valley patterns with sub‑micrometer precision. Designed for compact, low‑power smart devices, it offers a 3.3 V operation voltage, well‑suited for battery‑powered wearables, access‑control tags, and industrial IoT gateways. The sensor’s integrated analog‑to‑digital converter delivers a raw image resolution of 360 × 360 pixels, enabling rapid template generation and matching with proven algorithms that achieve > 99 % recognition rates.

With one of the smallest form‑factor footprints in the market, the module includes a dedicated microcontroller, SPI/I²C interface, and secure OTP memory for storing template data. Its low current draw (≤ 45 µA in standby) and robust packaging make it ideal for space‑constrained, long‑life deployments.
