Description of product


TDK InvenSense MOD-CH101 Ultrasonic Time-of-Flight (ToF) Sensor Module contains a CH-101 sensor on a small printed circuit board. Based on Chirp’s patented MEMS technology, the CH-101 is a system-in-package that integrates a PMUT (piezoelectric micromachined ultrasonic transducer) together with an ultra-low-power SoC (system on chip) in a miniature, reflowable package. The SoC runs Chirp’s advanced ultrasonic DSP algorithms and includes an integrated microcontroller that provides digital range readings via I2C. 

The CH-101 provides accurate range measurements to targets at distances up to 1.2m. The sensor works in any lighting conditions, including sunlight by using ultrasonic pulse-echo measurements and provides millimeter-accurate range measurements independent of the target’s color and optical transparency. The sensor’s wide Field-of-View (FoV) enables simultaneous range measurements to multiple objects in the FoV. The MOD_CH101-03-01 sensor module includes an omnidirectional acoustic housing with a 0.7mm diameter acoustic port and a 5.3mm outer diameter.
