Hello there, I am working on a lit bit of debugging for some publisher code using ModularSensors. I successfully connect to the server but get a 422 error code which means that though the POST request had the proper syntax, the body could not be processed. I’ve been trying to figure out what it could be, and I think it might have to do with the…[Read more]

There’s a section in the User Manual that should have been included in the shipment with your sensor (it’s also downloadable from here: https://metergroup.com/products/teros-12/teros-12-support/) that explains how to use the raw number collected by the sensor to calculate soil moisture content.

@shicks Thank you so much its working perfectly fine now. Also if you could explain to me how to convert the RAW data of the sensor with the units of measurement I want it would be really helpful.

It looks like you’re having the same issues a few other people have reported lately. We’re working on a fix, but in the meantime, the easiest thing to do is to replace all your “MyDocuments/Arduino/libraries” files with the stable versions from last summer. In order to do this, you’ll have to delete all the current library files on your PC. If y…[Read more]

That means your IDE’s Serial Monitor baud rate is not the same as the baud rate in your sketch

@shicks Its working now. Thank you. But the issue is with the b_address_change sketch. This is the output.
Shannon Hicks replied to the topic Connecting Arduino MEGA or NANO with Teros 12 Sensor in the forum Environmental Sensors 1 year, 7 months ago
Did you make sure the sensor is properly wired to your Mega, (tip to 5v, sleeve to GND, and ring to data) and that the pin number in the sketch matches whatever pin number you connected the data line to? If all the wiring is correct, then it might be an issue with the latest SDI12 library that a few people have reported. You could try r…[Read more]
aqua replied to the topic Connecting Arduino MEGA or NANO with Teros 12 Sensor in the forum Environmental Sensors 1 year, 7 months ago
@shicks When I connect the tip-power, ring-ground, and sleeve-data Arduino IDE can’t read my port & the light on the Arduino Mega stops. What’s the reason? This is the output its giving me ”
