  BuiltByTyler Sensor Kit - S19 TEMP ANALOG (MCP9700A)
  Board: ESP32-WROOM-32 DevKit V1 (30-pin), Arduino-ESP32 core 3.x, "ESP32 Dev Module"

  Reads the MCP9700A analog thermometer: 500 mV at 0 C, +10 mV per C.
  tempC = (millivolts - 500) / 10

  Wiring (module pin -> ESP32 pin):
    GND  -> GND
    VCC  -> 3V3
    AO   -> GPIO 34

  Library: none needed
  Serial Monitor: 115200 baud
