When the GPS module used for the ESP32-Cam project failed to get a reliable lock while bench testing, it became clear that a mockup was the best option. Development has its challenges, but not having reliable sensor data needn’t be one. Some digital and analog sensor data can be generated either by counters, timers, or a combination of the two. Other sensor data might follow a protocol like SPI, I2C, or UART data streams. For all of these sensor types, … Continue reading ESP-32 Flight Datalogger – Underground GPS
