ESP cat scare¶
The idea¶
Unfortunately, our carport is regularly abused as a cat toilet. This is to be turned off with an ultrasonic sound.
This device is a combination of the IoT multisensor and the light control component.
It consists of three pir sensors and a relay board which controls an ultrasonic generator. With this mini piezo tweeters are driven.
