Shannon Hicks replied to the topic Error setting Hydros21 address in the forum Environmental Sensors 2 years, 4 months ago
When you’re connected to the Mayfly with your computer, open the Arduino IDE’s Serial Monitor and check the settings of the dropdown box in the lower right hand part of the windows next to the baud rate. It should be set to “No line ending”. If you have it set to anything else, you’ll usually get an error when setting the address using that s…[Read more]
Matt Barney started the topic Error setting Hydros21 address in the forum Environmental Sensors 2 years, 4 months ago
I’m getting the error “Not a valid address” when using the b_address_change.ino sketch in Arduino IDE. However, the address does appear to be getting set as expected, and I can change it to 2 and back to 1; it outputs the error each time, so it just looks a little odd. I’ll attach the output from the serial monitor below.
This is with a new Gen 2…[Read more]
Shannon Hicks replied to the topic Hydros 21/Decagon CTD: reading error in the forum Environmental Sensors 2 years, 4 months ago
Yes, it’s just one line (currently line 107) of the MeterHydros21.h file that contains the most important change, which is this line: #<span class=”pl-k”>define</span> <span class=”pl-en”>HYDROS21_MEASUREMENT_TIME_MS</span> <span class=”pl-c1″>1000</span>
The previous setting was 500 milliseconds but it turns out the new Gen 2 CTD sensors need…[Read more]
Matt Barney replied to the topic Hydros 21/Decagon CTD: reading error in the forum Environmental Sensors 2 years, 4 months ago
We’ve just had a failure to communicate with our newest Hydros 21 sensors (likely Gen 2). While I’ve had success setting the address with the b_address_change sketch, my standard Mayfly code can’t talk to the sensor and returns values of -9999. It looks to me like the SDI-12 library has not changed since May 2021…[Read more]

Using the ModularSensors code for a Maxbotix HRXL Ultrasonic Range Finder below
it references a sonarSerial and mentions having to set it up in the “Setting for Additional Serial Ports” but I am unable to find the correct “settings” to start the serial port? What are the the best Groove Pins to use, for the Sonic pins? For a Trigger pin and…[Read more]

Scott, your study is a riveting read and very well done. I find your conclusions encouraging to the work I have been doing and to the field of EnviroDIY. Your analysis provides the answers to questions that we all […]
KBR Kings River started the topic Multiple OneWire Sensors Multiple Pins in the forum Environmental Sensors 2 years, 4 months ago
I would like to monitor temperature, of water, ground and air. I was thinking of building one wired sensor to the water, then another wired sensor to ground and air. Thus I would need two OneWire Bus Pins, .and the one OneWire Bus pin would have two sensors attached.
Using a few Arduino Example sketches I can get this to work and read, mu…[Read more]
