Hardware for temperature sensor system

Hello everyone, I am quite new at electronics, but would like to build a temperature sensor system, with a few sensors communicating by Wifi. This is the hardware i have for now. - Sensor: SHT31-F Digital Temperature and Humidity Sensor https://www.mouser.dk/ProductDetail/DFRobot/SEN0334?qs=vmHwEFxEFR84ghjxY3ys9g%3D%3D - ESP32-DevKitC-DA: https://www.mouser.dk/ProductDetail/Espressif-Systems/ESP32-DevKitC-DA?qs=sGAEpiMZZMu3sxpa5v1qruWiePTuESx6hH2IfzRelRM%3D - Battery holder, for 3x AA batteries https://www.mouser.dk/ProductDetail/Eagle-Plastic-Devices/12BH331P-R-GR?qs=XyqZYYwnJvGzPnBQuz3ZAw%3D%3D - Voltage regulator MISSING - I initially had placed a voltage regulator between the battery and the ESP32, to get the voltage to 3.3V, but i only found one that does 250 mA, which isn't enough for the ESP32 i believe I initially had the MCP1700 https://www.mouser.dk/ProductDetail/Microchip-Technology/MCP1700-3302E-TO?qs=h7tZ5KkzNMMPEB66r2rMQw%3D%3D https://ww1.microchip.com/downloads/en/DeviceDoc/MCP1700-Data-Sheet-20001826F.pdf - breadboard ( as i have nothing yet - this is my first project ): https://www.mouser.dk/ProductDetail/OSEPP-Electronics/LS-00047?qs=w%2Fv1CP2dgqofvkXBf4F3MQ%3D%3D - Capacitors. Some 1µF ceramic capacitors - Wires Some jumper wires and AWG 22 wires https://www.mouser.dk/ProductDetail/TE-Connectivity-Raychem/FLTWC0311-22-0?qs=N3jkMqSZCcOXFhd0JjK2HA%3D%3D https://www.mouser.dk/ProductDetail/Mikroe/MIKROE-2022?qs=uPV7ZbtEjc4uW4JvgAUfzA%3D%3D So my problem is that i am missing a voltage regulator, that can handle the ESP32. Any other oversights i have made would also be nice to know about :). I am for now planning to make 3 systems of these parts, that communicate over wifi. There might be a better way? I don't know. Any feedback on this project would be greatly appreciated :). (If missing parts can be found at mouser, it would be great, so i can get it all in the same place) Below is my attempt at a diagram. IDK if it makes sense...
