IoT Motor Monitoring PCB Design

I want to design an IoT-based motor monitoring PCB using an ESP32 microcontroller.
The board must include:
ESP32-WROOM module
DS18B20 temperature sensor (1-wire)
Vibration sensor (analog output, like SW-420 or similar)
ACS712 current sensor module (analog output)
5V input power supply
On-board 3.3V voltage regulator for ESP32
Proper decoupling capacitors
Pull-up resistor for DS18B20
Programming header for ESP32
Status LED
The board should be compact and suitable for industrial motor monitoring.
Please generate the schematic with proper component values and best design practices.

I will create a compact industrial IoT motor‑monitoring schematic per your spec with the listed module, sensors, power, headers, LED, decoupling, and protection.
Plan:
  1. Add core blocks: 5V input, 3.3V regulator, MCU module, programming header, status LED.
  2. Add sensors/interfaces: 1‑Wire temp with pull‑up; analog vibration input with bias and RC anti‑alias; current sensing path to ADC.
  3. Add input protection, bulk/local decoupling, grounding.
  4. Assign GPIOs, wire nets, label, and run ERC.
Click Start to execute. Let me know if you want any changes.
Use external ACS712 module
Pick on-board 3.3V regulator
Assign ESP32 pins
Add input protection
ADC filter values
