Is there any way to find a similar schematic of an RF temp sensor with an LCD display without any microcontroller involved? |

Did you check without the display, The mp probably is under |

Yessss... as far as I can see from the photos now, there is a black epoxy blob of chip-on-board under the display. I suppose it would be much more complex to avoid a microcontroller for such kind of projects. |
