Weather station GMX240 Power Consumption

Post by Markus Haist » Mon Oct 08, 2018 3:52 pm

Hello everyone,

we have Plug & Sense! SA-XTR 4G EU/BR * SAXB-4G-EU/BR plus Weather station GMX240 (WPO) Probe and External solar panel 7V 500mA (power accessory for P&S). Unfortunately, we cannot use the weather station to measure precipitation as power consumption is way too high for 24/7 measurement.

The idea is to put the weather station in deep sleep for 15 minutes (interval to send data from Plug&Sense) in case no rain detected. In case rain is detected we like to have one minute measurement and afterwards four minutes deep sleep.

In combination with the solar panel, we hope to receive a system that will work very long under normal rain/sun.

We need this to be programmed as with the online programming scenario does not allow this.

If someone has any other solution to keep the system running for at leat two to three month, your support is welcome.

Best regards,

Hi Markus,

Your proposal is feasible, you can program the code following the example codes that you will find in our website or in the IDE. If you find any problem doing the code we will help you but we can't do for you all the code from zero. If you need a programming service please contact with your sales agent. We're sorry but the PCS has been made just for standard working mode of the nodes.

Also you should take note that if it's raining for several hours or a couple of days the battery will discharge very fast so you should condition the time to sleep when raining depending of the battery level.

Hope this information helps to you if you have any other question, please feel free to ask.

We have the same problem of too High Power Consumption during the following behaviour that we need for hour monitoring system:
The SA XtremeP&S goes is in power sleep mode every 10 minutes and the GMX-240 is set to on-read-off mode every 10 minutes.
The the P&S is sending data every hour.

From your point of view, how can we solve this problem taking into account that:
- the battery of our P&S goes completely discharged after about 36 hours even if we have sunny days?
- an external solar panel of 7V - 500mA is plugged
- other 2 sensor are also plugged, namely Leaf wetness Phytos 31 and Vapor pressure, humidity, temperature, and atmospheric pressure in soil and air VP-4

Thanks a lot for your reply.

Is the weather station turned OFF after reading it?

Could you please share the code uploaded to the node with us?
