Remote GPS Sensor: Component Selection and GPS Coding
- Home automation systems use various sensors triggering behaviors like turning on lights based on presence, even using GPS coordinates for precise detection.
- The article discusses using Home Assistant and ESP Home for automations involving devices transmitting GPS coordinates as tags.
- Challenges arise in urban areas due to the reliance of ESP Home on stable Wi-Fi for data transmission from GPS sensors located remotely.
- The project transitions to using long-range radio frequency transmission for data from remote GPS and temperature sensors to a base station.
- Steps include building and programming the sensors, sender, receiver, and integrating with Home Assistant for automations.
- Specific hardware components required include ESP8266 board, BME680 temperature sensor, NMEA-based GPS sensor, and Dupont cables.
- The article details the wiring of components, the PlatformIO project setup, and the initial code implementation for sensor communication.
- Instructions and configurations are provided for integrating the Adafruit BME680 Library and reading temperature and GPS data using SoftwareSerial and TinyGPSPlus.
- The code examples demonstrate reading temperature and GPS data individually and then integrating both to periodically gather and print sensor readings.
- The project's aim is to create a remote sensor system using radio frequency for data transmission, bypassing the limitation of Wi-Fi connectivity in congested areas.
- The article focuses on the hardware, sensor programming, and initial setup, with future articles planned to explore the remote connection and data processing aspects.
