but ones that are quite small.
unlike a generic HC-SR04 which is under $10.
Define "quite small".
Hello there!I have used the APDS9960 sensor for several months and it is fairly decent. It is a combination of directional IR, color, and proximity sensors that can work for several projects. I am not sure what you are trying to use the ultrasonic sensor for, but perhaps the apds9960 can act in the interim. The sensor is a 3.3V board, so you may need logic level converting to control it, depending on what board you have. Give the link above a read and let me know what you think.
You are shopping wrong. :-DGo look at https://www.aliexpress.comThey have the HC-SR04 in the $0.75 range.
I need an ultrasonic sensor under $20
