GC UETCH101DLB0600

The UETCH101Dxxxxxx series is a miniature ultra-low-power ultrasonic Time-of-Flight (ToF) ranging module. Based on TDK's CH101 MEMS technology, it integrates a PMUT (Piezoelectric Micromachined Ultrasonic Transducer) with an ultra-low-power SoC in a compact, reflow-compatible package. The SoC runs Chirp's advanced ultrasonic DSP algorithms and outputs distance data directly via a microcontroller UART interface. The UETCH101Dxxxxxx provides accurate ranging to targets within 1.2 m (maximum range varies by product model). Using ultrasonic measurement, the sensor operates under any lighting condition — from full sunlight to complete darkness — and delivers millimeter-level ranging accuracy regardless of target color or optical transparency.
