ESP32 based Lora Ebyte E22-400T22S Reciever with Relays
Khan Aug 09,2025
The receiver module is a critical part of the wireless surveillance camera control system, designed for long-range, reliable operation using the LoRa Ebyte E22-400T22S at 433 MHz. Just like the transmitter, it leverages LoRa’s robust communication capabilities to ensure seamless data reception even in challenging outdoor environments.Upon receiving control commands from the transmitter, the receiver processes the data via an ESP32-S3 microcontroller and executes precise motor movements for the s...

ESP32 based Lora Ebyte E22-400T22S transmitter
Khan Aug 09,2025
This project focuses on replacing the traditional wired control system for surveillance camera tilt motion with a reliable long-range wireless solution. The motivation stemmed from challenges in wired setups, including distance limitations, frequent weather-related failures, and costly repairs.To achieve this, I designed a custom wireless remote control system using the LoRa-based Ebyte E22-400T22S module, operating at 433 MHz. This module offers an open-area communication range of up to 5 km, e...

CH340K USB-C Programmer with Auto-Reset (for ESP Chips)
M Aug 05,2025
For many embedded or custom ESP-based projects (like this one), a dedicated USB to TTL chip on the main PCB isn't always necessary—especially if firmware uploads are rare.In these cases, an external USB-to-serial programmer comes in handy.However, uploading firmware to ESP chips isn't always straightforward.As you may know, ESP chips require specific pin states (typically toggling EN and IO0) to enter boot mode. Without automation, you're left using awkward workarounds like holding down buttons,...

Smart Weighing Scale for Meat with Integrated Temperature Sensing and Wireless Connectivity
Quispe Jul 07,2025
This project presents the development of a smart electronic scale specifically designed for weighing meat products, including refrigerated or frozen items. The system integrates a high-precision load cell amplifier (HX711) for force measurement and a non-contact infrared temperature sensor (MLX90615) to monitor surface temperature. A dual-microcontroller architecture is used: the STM32 handles sensor acquisition and signal processing, while the ESP32-C3 provides Bluetooth and Wi-Fi communication...
