ESP32-Cam RGBW Light MQTT Controller

ESP32-Cam RGBW Light MQTT Controller

In this post the ESP32-Cam module will be used to operate a generic color LED strip using an IR LED. The actions of the ESP32-Cam module will be controlled using a MQTT broker and Node-Red. The Node-Red webUI will be provided to allow manual controls. Node-Red will also use scheduled nodes to control the lighting based on time of day. The LED strip in this post is an inexpensive RGBW LED strip. These power strips are not logically addressable. Addressable…

Water Level Monitoring with the ESP32-Cam Module

Water Level Monitoring with the ESP32-Cam Module

In this post the ESP32-Cam module will be used to monitor water levels using a HC-SR04 ultrasonic ranging module . The readings will be published to a MQTT broker through the WiFi network. Node-Red will be interfaced with the broker and used to process and display the readings in its WebUI. Node-Red will also operate a pump once thresholds are reached through the broker. Video from the ESP32-Cam will be gathered by Node-Red and included in its WebUI. This project…

RTL SDR ADS-B

RTL SDR ADS-B

In the last post, a video introduced the topic of ADS-B. This post will cover the topic in more detail. Automatic dependent surveillance broadcast is a technology used by aircraft to broadcast location, heading, and velocity. It’s part of the FAA’s NextGen system that was first deployed in 2007 and should be completed by 2030. The standard will likely be used internationally with the purpose of providing ground controllers and pilots situational awareness. This video provides insight into the FAA…
