“This sensor works well for guaranteeing 3.3v compatibility for distance sensors with controllers. Hwoever, the dimensions for mounting the sensor (the cans, vs the board) are not widely available and it's not physically the same as the HC-SR04. More widely availabel dimensions, and seeing more stokcists carry brackets for this sensor would be great.”
“Whilst NOT the same size as an HC-SR04, this sensor appears to work well with a 3v3 ESP32, and is manufactured to a good standard. It's dearer than an HC-SR04, but more versatile, given its extended supply voltage range. I would have given this product a 5 star rating, but feel that the web site is misleading, by stating that it is compatible with an HC-SR04. You have to drop down the description before you see the note relating to size. Hence it was only when I received the part, that I realise that I would now have to modify my project. Less about Dolphins please, and more about basic dimensions would be my advice to Pi Hut. I attach a photo of it mounted in my latest project.”
