Precision Sensor Board Update
I have continued working on this project and found a probe cover and cable housing. By not using the back of the cable housing I’ve been able to modify a RM Young 41390 Sensor Junction Box and make a usable Pressure, Temp, Humidity device to fit inside the multi-plate radiation shields. I’ve made some changes to the board connections so that it will solder to the probe housing ...[Read More]
Arduino DataLogger Board
Wanted to share my most recent attempt at a customized Arduino based (Mega2560) data logger board. I’ve used a Silicon Labs CP2104 USB interface and also contains: -DS3231 RTC with Battery B/U -uSD Card -4MB MRAM (SPI interface) – 3 Serial Port Headers (3.3V/5V) **I left Serial dedicated to the USB, but Serial1, 2, and 3 are avail. -3.3V/5V I2C headers -3.3V/5V SPI headers All digital...[Read More]
Precision Sensor Board
I recently designed a board that incorporates digital pressure, temperature, and dewpoint sensors I’ve called the PTU board. I deal with weather balloon tracking systems and the information sent back from the radiosondes is usually called PTU data (Pressure, Temperature, and Humidity). I’ve written 2 new Arduino libraries for the pressure and temp and reused an existing library for the...[Read More]
