Feb 19, 2026 · How to set up Ratgdo V2. Now I would like to run the ESP32 in a control box at the tank an broadcast the info to the kitchen via esp NOW. 01uF capacitor at the Q-node to shift the resonance frequency. When combined with an ESP32, it becomes a fast, local, battery-free, and cloud-free door sensor that integrates perfectly with Home Assistant. Reed switches are magnetically-actuated electrical switches which switch based on a magnetic field. Have always been interested in HA but travel full time for work with my camper. I didn't buy anything yet, and would love some input/direction for this project. . Measurement: 10kΩ voltage divider midpoint at Q-node leads to the amplification chain. 53I and Chamberlin security + garage door opener with magnetic reed switches for Home Assistant? Drive: ESP32 GPIO2 enters Q-node via 220Ω resistor. Nov 24, 2025 · A reed switch is one of the simplest and most reliable ways to detect when a door or window opens. In this tutorial we learn how to build our own security system for doors or windows with a reed switch. It is activated by the presence by a nearby magnetic field. May 27, 2018 · I set 4 interrupt pins for ESP32 (no. 2) to receive input signal from 4 push button switches when pressing each of them it will call interrupt function to execute a specific task (different 4 tasks Jan 18, 2025 · My Reed Switch Sensor wouldn’t trigger with ESP32—because the magnet was wrong. But then I ran accross the ESP32- S3 and my thoughts completely changed. A magnetic reed switch is an electronic sensor that acts like a button or a switch. Sensor Integration: Bosch BME280 for temperature, relative humidity, and air pressure. Reed-switch based rain tipping buckets. Jan 18, 2025 · In this guide, I’ll walk you through how to correctly wire a Reed Switch Sensor to ESP32, how to code it in MicroPython, and what magnetic gotchas to avoid if you want consistent readings. Finally decided to redo all the camper switch panel wiring and get HA in the camper, still working on tank sensor level readings using an ESP32 and an INA3221. To stimulate the reed switch I use a magnet with 2 sides (north and south). Analogue wind vanes and anemometers (e. It has the advantages of simple structure, small size and easy control. INA219 for onboard voltage and current measurement. g. At reed switch open the GPIO voltage is 4. The reed switch is the abbreviation of the dry reed switch. 9V. /** * ============================================================ * IoT Cargo Security System — ESP32-S3 Firmware * ============================================================ * Components: * - Reed Switch → Door tamper detection * - LDR → Light intrusion detection * - ADXL345 → Shock / tilt detection (I2C) * - GPS Module → Real Key Features Platform: Runs on most ESP32-based boards (tested on Lolin D32, DFRobot Firebeetle). It is a passive electronic switch element with contacts. , SparkFun Weather Meters). This project is useful for applications such as door/window sensors, magnetic proximity sensors, and various types of security systems. In this kit, there is a Keyestudio reed switch module, which mainly uses a MKA10110 green reed component.
