Another thermometer with humidity and light intensity sensors. There is two displays so you can see temperature from both side.

Of course it is on WiFi with web gui for settings and reading values, it can provide json data for another nodes, displays brightness is automatically adjusted according to surrounding light intensity, etc.

You need to placed it verticaly as you can see in photos as there is holes in bottom, so water will stay out (no need if use just indoors). You can place temp sensor inside but ESP32 and another electronics produce some heat so sensor will measure about 2 degrees more, so i have printed small case for SHT41(temp/humidity sensor) and place it externaly. It is designed to hold on 42mm diameter mast (for antennas). But mast holder is optional you can use just main round unit standallone.

It is partially printed with transparent PLA so you can see displays better and also LDR (light intensity sensor) can be more sensitive.
