Here’s some photos of various P2-based instrumentation projects I’ve been working on in the past couple of months during Melbourne’s COVID-19 lockdown.
Currently I’m building up a P2 weather station, that will incorporate ultrasonic anemometry, a tipping bucket rain gauge, plus temperature, pressure, humidity and UV measurement. Eventually this will also build in the ESP32 for field deployment/internet access.
For the anemometry part of this project the analog capability and smart pins of the P2 really shine. A couple of pics show my test setup and draft control screen where the transducer Rx envelopes and zero crossings are reported. Hope to post more about this project as it progresses.
