When I first started to elaborate on some ideas, I had the intention that the notes would help me remember so I could refresh later. It has become much more than that. The topics and ideas have given me better footing to…
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…
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…
