We are using it for a translator to connect a Vaisala HMP-155E to the ASOS. The original ASOS is RS-232 over fiber and we aren’t able to change the source code any longer. So adding a new sensor required me to make the HMP-155E talk to our system like it was a different sensor.…[Read more]

We used the 3.5 because of it’s 5V tolerant I/O. The Teensy 4.1 did not have that so the project stalled for a bit.

Maybe that already works in its existing state, but I haven’t see it mentioned anywhere. This is the new IC that runs the RPi Pico and can be used via the Arduino language.

They are very short supply.

Yes, we have solar to the charger and into (2)12V 9aH batteries (in parallel). The Teensy and Xbee are on a custom motherboard we designed. Has lots of the IO broken out and spots for Adafruit GPS, RTC battery, ESP32 (older requirement) and Wiz850io Ethernet.

Everything I was talking about is MQTT with Thingspeak.  I tested it on my Thingspeak connection I created. It was just allowing the micro-python code in the Xbee to handle all the network and MQTT items vice using the AT commands from the MayFly to the Xbee as it looks like is happening in the enviroDIY libraries.

Gonna let you all work through this on the mayfly code using the xbee transparent mode. If at some point you would like to use the micro-python option in the xbee I can provide some code to just use simple serial.println() on the mayfly to send payload to the xbee and it will handle all the MQTT stuff in the background.

We filled the pvc with spray foam to try and deal with moisture issues. All wires from thermistor were ran to a campbell datalogger at our Sterling, VA test facility and all…[Read more]

I know there are numerous soil temp/moisture sensors for depths close to surface, but looking for one that might have 5 to 6 different depths within a single probe.

Looking to measure depths of 4, 8, 12, 20 and 40″

This device wouldn’t be used in a weather balloon type environment, that’s just one of the areas I deal in most with NWS. I have a side business where I currently only sell NOAA Weather Radio / SAME Decoder modules for arduino and raspberry pi usage and wanted to expand my device offerings. I won’t post the site, cause that’s not really my…[Read more]

What is you data transmission rate? I know in the one I’m working on for NWS I’ve had to put the 2560 and the Xbee 900HP to sleep when not in use to conserve power. We are looking at a 7.2aH SLA battery with solar and regulator.
