Water Level Monitoring with the ESP32-Cam Module

February 27, 2023 Patrick Gilfeather

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

January 31, 2023 Patrick Gilfeather

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…

GPS Mapping with Viking using ESP-Now and GPSd

December 22, 2022 Patrick Gilfeather

The last post (https://www.cloudacm.com/?p=4185) ended with a video titled “Decoding GPS using an RTL SDR Receiver” that was posted August of 2020. The 2 software requirements for this method are RTKLIB (https://www.rtklib.com/rtklib_tutorial.htm) and GNSS-SDRLIB (https://github.com/taroz/GNSS-SDRLIB). The video mentioned that Google Maps didn’t display, however there was mention in comments about an API requirement. The video did introduce the option to port the output to another mapping program, one of which is Viking. On a side note, I found this video…
