Dragino SDI-12-lb to measure sapflow sensor sdi-12 IMPLEXX

[Ramon Lopez Jimenez]

Hi,

I have a problem to measure a sapflow sensor sdi-12 from IMPLEXX.io, connected to a dragino SDI-12-LB.

The routine to measure is:

* first send command SDI-12 using C!

* delay 140 seconds to make the measurement (need to heat...and other)

* after send D0!, return 5 values 

* after send D1!, return 4 values.

I configure dragino to measure every 15min.

I have a one battery and solar panel for the power sapflow sensor.

the problem is the delay of 140seconds, the max time I can active the output 12V from dragino is 65535msec. 65sec, but I need 140 seconds.

Can I have ON the dragino about 145 seconds ?

How I solve this problem ?

Thanks
