The MOD_CH101 sensor module is designed for rapid integration of
Chirp’s CH-101 ultrasonic Time-of-Flight (ToF) range sensor into
customer enclosures. It is especially useful for prototyping and small-
scale production in applications that are not extremely space
constrained. The module’s electronic interface is via a standard 8-pin
flat flex cable (FFC) connector. The module includes an acoustic
housing that determines the CH-101 sensor’s field-of-view. The
MOD_CH101-03-01 sensor module includes an omnidirectional
acoustic housing with a 0.7 mm diameter acoustic port and a 5.3 mm
outer diameter.
