Shannon Hicks replied to the topic Digi LTEBee on Mayfly v1.x in the forum Mayfly Data Logger 2 years, 3 months ago
No, the old LTEbee Adapter should not be used with a Mayfly v1.x board. You simply plug the Digi board directly into the Mayfly v1.x board with no adapter at all. Make the changes to the jumpers I mentioned above and you’ll enable the white and blue status LEDs that are built into the new Mayfly boards. The only thing missing is the orange RS…[Read more]

Thanks for this excellent detail.
So we could continue to use the LTEBee adapter with the Digi modem on a v1.1 Mayfly, which would retain the functionality of the white and blue modem status LEDs, and would connect the Bee socket’s pin to the proper status pin on the Digi (without need to modify SJ19), and we would not need the power jumper to…[Read more]

The purpose of the now-discontinued “EnviroDIY LTEbee Adapter” was to allow people to use the Digi brand LTE cellular module with the Mayfly v0.5 boards by doing 3 main thing: providing sufficient power (current) to the cell module, connecting pin 13 of the Digi board to pin 12 of the Mayfly bee socket, and giving the user some LEDs to show…[Read more]

What jumper settings are required to operate a Digi XBee LTE-M on Mayfly v1.x? I’ve read the jumper settings page, which details what each jumper does, including the Bee socket-related ones, but without being familiar with the electrical requirements of the Digi, I’m unclear what needs to change. I have a likely-failed Mayfly v0.5b, which I’d like…[Read more]

Hi,
I am checking the calibration on several new Hydros21. I don’t see how to calibrate the sensors themselves, so it would be useful to display (at the data portal) a calculated variable for the Hydros21 in addition to the specific conductance coming from the sensor. Calculating the variable in the logger code looks doable to me thanks to t…[Read more]

Yeah, great question. I would love to have Nitrates, Phosphorous, Dissolved Oxygen and Ph capabilities also. I suspect that there is a calibration problem for a in stream sensor for these parameters.

Shannon Hicks replied to the topic MS One-Wire Power in the forum Environmental Sensors 2 years, 3 months ago
Onewire sensors like the DS18b20 don’t like to have their bus power cycled on and off. Back when I last experimented with them (with a different sketch not related to ModularSensors), if you’ve got the sensor connected to the switched power supply, you had to do “DSsensors.begin();” each time the logger woke and powered up the switched power b…[Read more]

hi Everyone,
I am new to the EnviroDIY world. I work at a nature center and we just installed our first water monitor. At the moment all we have is temp, depth and conductivity, but we are really after a nitrate monitor. We share a border with a golf course that drains directly into our pond, so being able to link a flood of nitrates di…[Read more]

To connect 3 pin One-Wire temperature senor I had wanted to use the Grove D10-11 port.
Power to 3.3V_SW
Sensor to D10
Ground to GND
