This project focuses on designing a custom PCB using the ESP32-S3-MINI-1-N8 microcontroller. The PCB integrates an ENS210 temperature and humidity sensor, a WS2812B RGB LED for visual feedback, and a power regulation system using the TLV75801 LDO voltage regulator. The design also includes TVS protection diodes for USB input safety.

Learn how to use temperature and humidity sensor with ESP32, how to connect DHT11 or DHT22 temperature and humidity sensor to ESP32, how to program ESP32 step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with ESP32.

This tutorial shows how to use the DHT11 and DHT22 temperature and humidity sensors with the ESP32 using Arduino IDE. We’ll go through a quick introduction to these sensors, pinout, wiring diagram, and finally the Arduino sketch.

This repository contains the hardware design, firmware, and HTTP backend for a small battery powered WiFi temperature and humidity sensor. The firmware is written in C, using ESP-IDF, which is based on FreeRTOS. The backend is written in …

Apr 3, 2025 · This Smart Sensor PCB is designed to integrate multiple sensors with an ESP32-DevKit-V1, allowing real-time environmental monitoring and data collection.
