I think this is especially for the americans😂

Great intractable. I am building something similar, but it is cloud based. Your wifi setup method looks very professional.

It was much faster than the multiplexer i used. I can not remember the exact figures.

I would also like a raspberry pi contest. It was not done this year.

I also hope it will still happen.

1) Could you install the blink sketch on the ESP32 higrow soil sensor?2) It seems like the your ESP32 libraries did not install. Make sure you go through all the steps.3) You should have added the following line in the arduino ide in file>preferences: https://dl.espressif.com/dl/package_esp32_index.json4) Install the ESP32 Libraries from Tools>Board>Boards Manager. Search for esp32 by espressif systems.

What I ment was: “It was passable for to use the arduino ide in windows 7 and 8 to upload the sketch to the ESP32. Can you upload the blink appDid you add the additional boards manager url (step 1)Did you install the esp32 librariesDid you select the correct boardTry to run the example in file>examples>examples for wemos wifi&bluetooth battery>SD(esp32). They use the FS.h library.FS.h was supposed to be installed with the esp32 libraries.

I could upload the sketch from windows 7 and 8.

Is it possible to load any other ESP32 sketch like blink?

I will suggest capacitive soil moisture sensors. DFrobot and a few companies produce them. Higrow attached one two an ESP32. Capacitive sensors have no metal in contact with soil.

Raspberry PIRepurposing electronics: Use electronics, circuits, sensors etc for things that they were not originally attended for.

I like the way a humidity sensor is used to measure soil moisture. All this cheap resistive probes corrode and destroy themselfs with electrolysis.

You are welcome to do it. I do not have any NB-IoT experience. What I do know is that it should be passable to connect a gprs module to the ESP32 and send data to the internet. I could not do it for know because I do not have a GPRS module and time . This is only my hobby and I do not do contract work. Adding a GPRS module may solve many of the power consumption the device currently have. If you build this instructable, please upload photos. I will apreciate.

Hi, replace the resistive soil moisture sensor with a capacitive soil moisture sensor. These resistive soil moisture sensors suffer from electrolysis.

I like the fact that you build your own sensor. The other entries in the sensor contest only show how other sensors is used.

Useful project. Tnx for the project.

Tnx for the share. I like the mini bell siphon. I designed a 3d printed bell siphon for an IoT rain gauge. It works 99% of the time, but some times the bell siphon leaks. By leaking I mean one drop enter the siphon, and then one drop is siphoned out, where all is supposed to be siphoned. Any advice may help. My project is at https://www.instructables.com/Bell-Siphon-Rain-Gauge/

Hi, the image on instructables preview is rendered incorrect. The file is however correct. Download it and see how it appears in you printing software. I am still working on improvements. I now use ABS glue (juice) instead of super glue to stick all together and waterproof/airtight the complete assembled item.

This can be very handy. It is really practical

Hi Andrew,Nice project complete projectThe RG 11 rain sensor is in my mind for a long time.
