I am a beginner in electronics and was looking for some advice. I was contemplating getting some HT7333's for projects. One of the things that I want to do is a battery powered temperature sensor. I saw a write-up on the web of someone using one battery with an ESP8266 and DS18B20 with an HT7333. The max voltage for the HT7333 is 12V it appears. It seems to bring it down to 3.3V.
If I were to use just one battery with an HT7333, would the voltage only be ~1.5V? It doesn't step up the voltage as well, right?
I'm just looking for a cheap way to place a few temperature sensors powered by batteries (and hopefully have long battery life).
