This Application note covers the hardware and software considerations for migrating to ICM 20948

This purpose of this document is to walk through the hardware setup, the execution of the GUI and the evaluation of ICU-20201 sensors. It explains all the available tools and support options that can be used to configure the device to achieve the best optimal performance.

This guide will explain the software and hardware setup of the floor type detection and cliff detection for robotic vacuum applications using two CH101 or ICU-10201 sensors. Floor type detection is the differentiation between hard floors (hardwood, tile, etc) and soft floors (carpets). Cliff detection is the detection of a cliff, such as an overhanging ledge, stairs, or other similar risk to a Robotic Vacuum Cleaner (RVC).
For clarity and simplicity, unless otherwise specified, any information referring to the CH101 in this document will also apply to the ICU-10201.

The purpose of this document is to provide information on the acoustic housing reference designs for the Chirp CH201 and ICU-20201 ultrasonic sensors. This document will provide an overview of how to compare acoustic housing designs and present performance profiles of the reference designs. All dimensions mentioned in this document are in mm, unless otherwise specified.

This guide will explain the process to setup and run the liquid level detection demo. Using a liquid level detection demo with Chirp sensor module, the amount of liquid in a cup can be distinguished. Using automatic parameter settings, the demo can demonstrate a cup in an empty or semi-filled state to be detected by a sensor and then filled to the parameter’s set level percentage. The liquid level demo is standalone setup and can be used without an external GUI or computer software. For a more refined demonstration or to see output plots, refer to the reference documentation section for the reference design write up.

This document details the specification, programming, and operation of an EV_MOD_CH101-01-02 (also referred to as the EV_MOD_CH101 in the remainder of this document) ultrasonic sensor evaluation module. The module board incorporates a CH101 Ultrasonic Sensor device with an 45° field-of-view acoustic housing assembly, a capacitor and an FPC/FFC connector. This evaluation module can perform pitch-catch and pulse-echo range-finding at distances from 4 cm to 1.2m. Several programming options are available for medium and short-range applications.

This guide will explain the software and hardware setup of the ultrasonic social distancing reference design development kit. Using Chirp CH101 sensor modules, two social distancing devices can interact with each other to notify the users that they need to socially distance, including early distance detection. With two devices there is a 360° field of view (FoV). Using different LED lights, chimes and buzzer vibration notifications, the user will be alarmed that they need to socially distance within a detection latency of 1 second.
